	Title	Baryon states with hidden charm in the extended local hidden gauge approach			Type	Journal Article
	Year	2016	Publication	European Physical Journal A	Abbreviated Journal	Eur. Phys. J. A
	Volume	52	Issue	3	Pages	43 - 16pp
	Keywords
	Abstract	The s-wave interaction of (D) over bar Lambda(c), (D) over bar Sigma(c),(D) over barLambda(c), (D) over barSigma(c) and (D) over bar Sigma(c), (D) over barSigma(c), is studied within a unitary coupled channels scheme with the extended local hidden gauge approach. In addition to the Weinberg-Tomozawa term, several additional diagrams via the pion exchange are also taken into account as box potentials. Furthermore, in order to implement the full coupled channels calculation, some of the box potentials which mix the vector-baryon and pseudoscalar-baryon sectors are extended to construct the effective transition potentials. As a result, we have observed six possible states in several angular momenta. Four of them correspond to two pairs of admixture states, two of (D) over bar Sigma(c) – (D) over barSigma(c) with J – 1/2, and two of (D) over bar Sigma(c)* – (D) over barSigma(c) with J = 3/2. Moreover, we find a (D) over barSigma(c) resonance which couples to the (D) over bar Lambda(c) channel and one spin degenerated bound state of (D) over barSigma(c)* with J = 1/2, 5/2.

	Title	*The K(K)over-bar pi decay of the f(1) (1285) and its nature as a K(K)over-bar – cc molecule**			Type	Journal Article
	Year	2015	Publication	Physics Letters B	Abbreviated Journal	Phys. Lett. B
	Volume	750	Issue		Pages	609-614
	Keywords
	Abstract	We investigate the decay of f(1) (1285) > pi K (K) over bar with the assumption that the f(1) (1285) is dynamically generated from the K(K) over bar – cc interaction. In addition to the tree level diagrams that proceed via f(1)(1285) -> K(K) over bar – cc -> pi K (K) over bar, we take into account also the final state interactions of K (K) over bar -> K (K) over bar and pi K -> pi K. The partial decay width and mass distributions of f(1) (1285) -> pi K (K) over bar are evaluated. We get a value for the partial decay width which, within errors, is in fair agreement with the experimental result. The contribution from the tree level diagrams is dominant, but the final state interactions have effects in the mass distributions. The predicted mass distributions are significantly different from phase space and tied to the K*(K) over bar – cc nature of the f(1) (1285) state.

	Title	Investigating the nature of light scalar mesons with semileptonic decays of D mesons			Type	Journal Article
	Year	2015	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	92	Issue	5	Pages	054038 - 17pp
	Keywords
	Abstract	We study the semileptonic decays of D-s(+), D+, and D-0 mesons into the light scalar mesons [f(0)(500), K-0()(800), f(0)(980), and a(0)(980)] and the light vector mesons [rho(770), omega(782), K-(892), and phi(1020)]. With the help of a chiral unitarity approach in coupled channels, we compute the branching fractions for scalar meson processes of the semileptonic D decays in a simple way. Using current known values of the branching fractions, we make predictions for the branching fractions of the semileptonic decay modes with other scalar and vector mesons. Furthermore, we calculate the pi(+)pi(-), pi eta, pi K, and K+K- invariant mass distributions in the semileptonic decays of D mesons, which will help us clarify the nature of the light scalar mesons.

	Title	*LHCb pentaquark as a (D)over-barSigma(c) – (D)over-barSigma(c) molecular state**			Type	Journal Article
	Year	2015	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	92	Issue	9	Pages	094003 - 6pp
	Keywords
	Abstract	We perform a theoretical analysis of the Lambda(b) -> J/psi K(-)p reaction from where a recent LHCb experiment extracts a Lambda(1405) contribution in the K(-)p spectrum close to threshold and two baryon states of hidden charm in the J/psi p spectrum. We recall that baryon states of this type have been theoretically predicted matching the mass, width and J(P) of the experiment; concretely some states built up from the J/psi N, (D) over barLambda(c), (D) over barSigma(c), (D) over bar Sigma(c)* and (D) over barSigma(c) coupled channels. We assume that the observed narrow state around 4450 MeV has this nature and we are able to describe simultaneously the shapes and relative strength of the the K(-)p mass distribution close to threshold and the peak of the J/psi p distribution, with values of the J/psi p coupling to the resonance in line with the theoretical ones. The nontrivial matching of many properties gives support to a J(P) = 3/2(-) assignment to this state and to its nature as a molecular state mostly made of (D) over barSigma(c) and (D) over barSigma(c)*.

	Title	Lambda(b) -> J/psi K Xi decay and the higher order chiral terms of the meson baryon interaction			Type	Journal Article
	Year	2015	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	92	Issue	7	Pages	076015 - 10pp
	Keywords
	Abstract	We study the weak decay of the Lambda(b) into J/psi K Xi. and J/psi eta Lambda states, and relate these processes to the Lambda(b) -> J/psi(K) over barN decay mode. The elementary weak transition at the quark level proceeds via the creation of a J/psi meson and an excited sud system with I = 0, which upon hadronization leads to (K) over barN or eta Lambda pairs. These states undergo final-state interaction in coupled channels and produce a final meson-baryon pair. The K. state only occurs via rescattering, hence making the Lambda(b) -> J/psi K Xi process very sensitive to the details of the meson-baryon interaction in strangeness S = -1 and isospin I = 0. We show that the corresponding invariant mass distribution is dominated by the next-to-leading-order terms of the chiral interaction. The I = 0 selectivity of this decay, and its large sensitivity to the higher-order terms, makes its measurement very useful and complementary to the K- p -> K Xi cross section data. The rates of the Lambda(b) -> J/psi K Xi and Lambda(b) -> J/psi eta Lambda invariant mass distributions are sizable compared to those of the Lambda(b) -> J/psi(K) over barN decay, which is measured experimentally, and thus, we provide arguments for an experimental determination of these decay modes that will help us understand better the chiral dynamics at higher energies.

	Title	*The rho(omega) B(B) interaction and states of J=0, 1, 2**			Type	Journal Article
	Year	2016	Publication	European Physical Journal C	Abbreviated Journal	Eur. Phys. J. C
	Volume	76	Issue	2	Pages	82 - 12pp
	Keywords
	Abstract	In this work, we study systems composed of a rho/omega and B* meson pair. We find three bound states in isospin, spin-parity channels (1/2, 0(+)), (1/2, 1(+)), and (1/2, 2(+)). The state with J = 2 can be a good candidate for the B-2*(5747). We also study the rho B system, and a bound state with mass 5728 MeV and width around 20 MeV is obtained, which can be identified with the B-1(5721) resonance. In the case of I = 3/2, one obtains repulsion and, thus, no exotic (molecular) mesons in this sector are generated in the approach.

	Title	Weak decay of Lambda(+)(c) for the study of Lambda(1405) and Lambda(1670)			Type	Journal Article
	Year	2015	Publication	Physical Review C	Abbreviated Journal	Phys. Rev. C
	Volume	92	Issue	5	Pages	055204 - 8pp
	Keywords
	Abstract	We study the Lambda(c) decay process to pi(+) and the meson-baryon final state for the analysis of Lambda resonances. Considering the Cabibbo-Kobayashi-Maskawamatrix, color suppression, diquark correlation, and the kinematical condition, we show that the final meson-baryon state should be in a pure I = 0 combination, when the meson-baryon invariantmass is small. Because the I = 1 contamination usually makes it difficult to analyze Lambda resonances directly from experiments, the Lambda(c) decay is an ideal process to study Lambda resonances. Calculating the final-state interaction by chiral unitary approaches, we find that the pi Sigma invariant mass distributions have the same peak structure in the all charge combination of the pi Sigma states related to the higher pole of the two poles of the Lambda(1405). Furthermore, we obtain a clear Lambda(1670) peak structure in the (K) over bar N and eta Lambda spectra.

	Title	chi(c0)(1P) decay into (Sigma)over-bar Sigma pi search of an I=1, 1/2(-) baryon state around (K)over-barN threshold			Type	Journal Article
	Year	2016	Publication	Physics Letters B	Abbreviated Journal	Phys. Lett. B
	Volume	753	Issue		Pages	526-532
	Keywords
	Abstract	We present the theoretical study of the process chi(c0)(1P) -> (Sigma) over bar Sigma pi decay, by taking into account the pi Sigma and pi(Sigma) over bar final state interactions of the final meson-baryon pair based on the chiral unitary approach. We show that the process filters the isospin I = 1 in the pi Sigma channel and offers a reaction to test the existence of an I = 1 state with strangeness S = -1 and spin-parity J(p) = 1/2(-) around the (K) over barN threshold predicted by some theories and supported by some experiments.

	Title	*Photoproduction of the f(2)'(1525), a(2)(1320), and K-2() (1430)**			Type	Journal Article
	Year	2016	Publication	Physical Review C	Abbreviated Journal	Phys. Rev. C
	Volume	93	Issue	2	Pages	025202 - 8pp
	Keywords
	Abstract	Assuming that the f(2)'(1525), a(2)(1320), and K-2() (1430) resonances are dynamically generated states from vector-meson-vector-meson interactions in the s-wave with spin S = 2, we study the gamma p -> f(2)'(1525)p, gamma p -> a(2)(0)(1320)p, and gamma p -> K-2()(1430)Lambda(Sigma) reactions. These reactions proceed in the following way: the incoming photon first mutates into a rho(0), omega, or phi meson via vector-meson dominance, which then interacts with the rho(0), omega, or K* emitted by the incoming proton to form the tensor mesons f(2)(')(1525), a(2)(1320), and K-2(*)(1430). The picture is simple and has no free parameters, as all the parameters of the mechanism have been fixed in previous studies. We predict the differential and total cross sections of these reactions. The results can be tested in future experiments and therefore offer new clues about the nature of these tensor states.

	Title	*Role of the f(1)(1285) state in the J/ psi -> phi(K)over-barK and J/psi -> phi f(1) (1285) decays**			Type	Journal Article
	Year	2016	Publication	Physics Letters B	Abbreviated Journal	Phys. Lett. B
	Volume	753	Issue		Pages	591-594
	Keywords
	Abstract	We study the role of the f(1)(1285) resonance in the decays of J/psi -> phi(K) over barK* and J/psi -> f(1) (1285). The theoretical approach is based on the results of chiral unitary theory where the f1(1285) resonance is dynamically generated from the K* (K) over bar -c.c. interaction. In order to further test the dynamical nature of the f(1)(1285) state, we investigate the J/psi -> phi(K) over barK* decay close to the (K) over barK* threshold and make predictions for the ratio of the invariant mass distributions of the J/psi -> phi(K) over barK* decay and the J/psi -> phi f(1)(1285) partial decay width with all the parameters of the mechanism fixed in previous studies. The results can be tested in future experiments and therefore offer new clues on the nature of the f(1) (1285) state.
