	Title	Semileptonic transition of Sigma(b) to Sigma in light cone QCD sum rules			Type	Journal Article
	Year	2012	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	85	Issue	1	Pages	016002 - 8pp
	Keywords
	Abstract	We use distribution amplitudes of the light Sigma baryon and the most general form of the interpolating current for heavy Sigma(b) baryon to investigate the semileptonic Sigma(b) -> Sigma l(+)l(-) transition in light cone QCD sum rules. We calculate all 12 form factors responsible for this transition and use them to evaluate the branching ratio of the considered channel. The order of branching fraction shows that this channel can be detected at LHC.

	Title	*Prediction of D-multi-rho states**			Type	Journal Article
	Year	2012	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	86	Issue	9	Pages	094019 - 10pp
	Keywords
	Abstract	We present a study of the many-body interaction between a D* and multi-rho. We use an extrapolation to SU(4) of the hidden gauge formalism, which produced dynamically the resonances f(2)(1270) in the rho rho interaction and D-2* (2460) in the rho D* interaction. We then let a third particle, rho, D, or a resonance, collide with them, evaluating the scattering amplitudes in terms of the fixed center approximation of the Faddeev equations. We find several clear resonant structures above 2800 MeV in the multibody scattering amplitudes. They would correspond to new charmed resonances, D-3, D-4, D-5, and D-6, which are not yet listed in the Particle Data Group, which would be analogous to the rho(3)(1690), f(4)(2050), rho(5)(2350), f(6)(2510) and K-3(1780), K-4(2045), K-5(2380) described before as multi-rho and K*-multi-rho states, respectively.

	Title	*Prediction of an I=1 D(D)over-bar state and relationship to the claimed Z(c)(3900), Z(c)(3885)**			Type	Journal Article
	Year	2014	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	90	Issue	1	Pages	016003 - 13pp
	Keywords
	Abstract	We study here the interaction of D (D) over bar* in the isospin I = 1 channel in light of recent theoretical advances that allow us to combine elements of the local hidden gauge approach with heavy quark spin symmetry. We find that the exchange of light q (q) over bar is Okubo-Zweig-Iizuka (OZI) suppressed and thus we concentrate on the exchange of heavy vectors and of two pion exchange. The latter is found to be small compared to the exchange of heavy vectors, which then determines the strength of the interaction. A barely D (D) over bar* bound state decaying into eta(c)rho and pi J/psi is found. At the same time we reanalyze the data of the BESIII experiment on e(+)e(-) -> pi(+/-)(D (D) over bar)(-/+), from where a Z(c)(3885) state was claimed, associated to a peak in the (D (D) over bar)(-/+) invariant mass distribution close to threshold, and we find the data compatible with a resonance with mass around 3875 MeV and width around 30 MeV. We discuss the possibility that this and the Z(c)(3900) state found at BESIII, reconfirmed at 3894 MeV at Belle, or 3885 MeV at CLEO, could all be the same state and correspond to the one that we find theoretically.

	Title	B-0 and B-s(0) decays into J/psi plus a scalar or vector meson			Type	Journal Article
	Year	2014	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	90	Issue	11	Pages	114004 - 9pp
	Keywords
	Abstract	We extend a recent approach to describe the B-0 and B-s(0) decays into J/psi f(0)(500) and J/psi f(0)(980), relating it to the B-0 and B-s(0) decays into J/psi and a vector meson, phi, rho, K. In addition, the B-0 and B-s(0) decays into J/psi and kappa(800) are evaluated and compared to the K vector production. The rates obtained are in agreement with the available experiment while predictions are made for the J/psi plus kappa(800) decay.

	Title	*Ds0(2317)(+) in the decay of Bc into J/Psi DK**			Type	Journal Article
	Year	2016	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	93	Issue	5	Pages	054028 - 9pp
	Keywords
	Abstract	In this paper we study the relationship between the D-s0(2317)(+) resonance and the decay of the B-c meson into J/Psi DK. In this process, the B-c meson decays first into J/Psi and the quark pair c (s) over bar, and then the quark pair hadronizes into DK or D-s eta components, which undergo final state interaction. This final state interaction, generating the D-s0(2317)(+) resonance, is described by the chiral unitary approach. With the parameters which allow us to match the pole position of the D-s0(2317)(+), we obtain the DK invariant mass distribution of the decay B-c -> J/Psi DK, and also the rate for B-c -> J/Psi D-s0(2317). The ratio of these two magnitudes is then predicted.

	Title	Discussion on triangle singularities in the Lambda(b) -> J/psi K(-)p reaction			Type	Journal Article
	Year	2016	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	94	Issue	7	Pages	074039 - 10pp
	Keywords
	Abstract	We have analyzed the singularities of a triangle loop integral in detail and derived a formula for an easy evaluation of the triangle singularity on the physical boundary. It is applied to the Lambda(b) -> J/psi K(-)p process via Lambda-charmonium-proton intermediate states. Although the evaluation of absolute rates is not possible, we identify the chi(c1) and the psi(2S)as the relatively most relevant states among all possible charmonia up to the psi(2S). The Lambda(1890)chi(c1)p loop is very special, as its normal threshold and triangle singularities merge at about 4.45 GeV, generating a narrow and prominent peak in the amplitude in the case that the chi(c1)p is in an S wave. We also see that loops with the same charmonium and other Lambda hyperons produce less dramatic peaks from the threshold singularity alone. For the case of chi(c1)p -> J/psi p and quantum numbers 3/2(-) or 5/2(+), one needs P and D waves, respectively, in the chi(c1)p, which drastically reduce the strength of the contribution and smooth the threshold peak. In this case, we conclude that the singularities cannot account for the observed narrow peak. In the case of 1/2(+), 3/2(-) quantum numbers, where chi(c1)p -> J/psi p can proceed in an S wave, the Lambda(1890)chi(c1)p triangle diagram could play an important role, though neither can assert their strength without further input from experiments and lattice QCD calculations.

	Title	*Line shape and D-(())(D)over-bar(()()) probabilities of psi(3770) from the e(+) e(-) -> D(D)over-bar reaction*			Type	Journal Article
	Year	2019	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	99	Issue	7	Pages	076002 - 17pp
	Keywords
	Abstract	We have performed a calculation of the D (D) over bar, D (D) over bar, D(D) over bar, D(D) over bar components in the wave function of the psi(3770). For this we make use of the P-3(0) model to find the coupling of psi(3770) to these components, that with an elaborate angular momentum algebra can be obtained with only one parameter. Then we use data for the e(+)e(-) -> D (D) over bar reaction, from where we determine a form factor needed in the theoretical framework, as well as other parameters needed to evaluate the meson-meson self-energy of the psi(3770). Once this is done we determine the Z probability to still have a vector core and the probability to have the different meson components. We find Z about 80%-85%, and the individual meson-meson components are rather small, providing new empirical information to support the largely q (q) over bar component of vector mesons, and the psi(3770) in particular. A discussion is done of the meaning of the terms obtained for the case of the open channels where the concept of probability cannot be strictly used.

	Title	*Molecular states of DDKbar nature**			Type	Journal Article
	Year	2023	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	107	Issue	3	Pages	034006 - 12pp
	Keywords
	Abstract	We study the interaction of two D* and a over bar K* by using the fixed center approximation to the Faddeev equations to search for bound states of the three-body system. Since the DD interaction is attractive and gives a bound state, and so is the case of the D* over bar K* interaction, where the JP = 0+ bound state is identified with the X0(2900), the DD over bar K* system leads to manifestly exotic bound states with ccs open quarks. We obtain bound states of isospin I = 1=2, negative parity and total spin J = 0, 1, 2. For J = 0 we obtain one state, and for J = 1, 2 we obtain two states in each case. The binding energies range from 56 to 152 MeV and the widths from 80 to 100 MeV.

	Title	X(3960) seen in Ds plus Ds- as the X(3930) state seen in D plus D			Type	Journal Article
	Year	2023	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	107	Issue	3	Pages	034007 - 5pp
	Keywords
	Abstract	We perform a calculation of the interaction of the D over bar D, Ds over bar Ds coupled channels and find two bound states, one coupling to DD over bar and another one at higher energies coupling mostly to D+s D-s . We identify this latter state with the X0(3930) seen in the D+D- mass distribution in the B+ -D+D-K+ decay, and also show that it produces an enhancement of the D+s D-s mass distribution close to threshold which is compatible with the recent LHCb observation in the B+ -D+s D-s K+ decay which has been identified as a new state, X0(3960).

	Title	a(0)(980) – f(0)(980) mixing in chi(c1) -> pi(0)f(0)(980) -> pi(0)pi(+)pi(-) and chi(c1) -> pi(0) a(0)(980) -> pi(0)pi(0)eta			Type	Journal Article
	Year	2017	Publication	Physics Letters B	Abbreviated Journal	Phys. Lett. B
	Volume	775	Issue		Pages	94-99
	Keywords	Isospin-breaking; a(0)(980) – f(0)(980) mixing; Charmonium decays; Scalar meson states
	Abstract	We study the isospin breaking in the reactions chi(c1) -> pi(0)pi(+)pi(-) and chi(c1) -> pi(0)pi(0)eta and its relation to the a(0)(980) – f(0)(980) mixing, which was measured by the BESIII Collaboration. We show that the same theoretical model previously developed to study the chi(c1) -> eta pi(+)pi(-) reaction (also measured by BESIII), and further explored in the predictions to the eta(c) -> eta pi(+)pi(-), can be successfully employed in the present study. We assume that the chi(c1) behaves as an SU(3) singlet to find the weight in which trios of pseudoscalars are created, followed by the final state interaction of pairs of mesons to describe how the a(0)(980) and f(0)(980) are dynamically generated, using the chiral unitary approach in coupled channels. The isospin violation is introduced through the use of different masses for the charged and neutral kaons, either in the propagators of pairs of mesons created in the chi(c1) decay, or in the propagators inside the T matrix, constructed through the unitarization of the scattering and transition amplitudes of pairs of pseudoscalar mesons. We find that violating isospin inside the T matrix makes the pi(0)eta -> pi(+)pi(-) amplitude nonzero, which gives an important contribution and also enhances the effect of the K (K) over bar term. We also find that the most important effect in the total amplitude is the isospin breaking inside the T matrix, due to the constructive sum of pi(0)eta -> pi(+)pi(-) and K (K) over bar -> pi(+)pi(-), which is essential to get a good agreement with the experimental measurement of the mixing.
