  Title Branching fraction of tau(-) -> pi(-KsKs0)-K-0(pi(0))nu(tau) decays Type Journal Article
  Year 2012 Publication Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 86 Issue (down) 9 Pages 092013 - 9pp  
  Keywords  
  Abstract We present a study of tau(-) -> pi(-KsKs0)-K-0(pi(0))nu(tau) and tau(-) -> (K-KsKs0)-K-0(pi(0))nu(tau) decays using a data set of 430 million tau lepton pairs, corresponding to an integrated luminosity of 468 fb(-1), collected with the BABAR detector at the PEP-II asymmetric energy e(+)e(-) storage rings. We measure branching fractions of (2.31 +/- 0.04 +/- 0.08) x 10(-4) and (1.60 +/- 0.20 +/- 0.22) x 10(-5) for the tau(-) -> pi(-KsKs0)-K-0 nu(tau) and tau(-) -> pi(-KsKs0)-K-0 pi(0)nu(tau) decays, respectively. We find no evidence for tau(-) -> (K-KsKs0)-K-0 nu(tau) and tau(-) -> (K-KsKs0)-K-0 pi(0)nu(tau) decays and place upper limits on the branching fractions of 6.3 x 10(-7) and 4.0 x 10(-7) at the 90% confidence level.

  Title Study of the baryonic B decay B- -> Sigma(++)(c) (p)over-bar pi(-)pi(-) Type Journal Article
  Year 2012 Publication Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 86 Issue (down) 9 Pages 091102 - 8pp  
  Keywords  
  Abstract We report the measurement of the baryonic B decay B- -> Sigma(++)(c)(p) over bar pi(-)pi(-). Using a data sample of 467 x 10(6) B (B) over bar pairs collected with the BABAR detector at the PEP-II storage ring at SLAC, the measured branching fraction is (2.98 +/- 0.16((stat)) +/- 0.15((syst)) +/- 0.77((Ac))) x 10(-4), where the last error is due to the uncertainty in B(A(c)(+) -> pK(-)pi(+)). The data suggest the existence of resonant subchannels B- -> A(c)(2595)(+) (p) over bar pi(-) and, possibly, B- -> Sigma(++)(c) (Delta) over bar (--)pi(-). We see unexplained structures in m(Sigma(++)(c)pi(-)pi(-)) at 3.25 GeV/c(2), 3.8 GeV/c(2), and 4.2 GeV/c(2).

  Title Measurement of the inclusive nu(mu) charged current cross section on carbon in the near detector of the T2K experiment Type Journal Article
  Year 2013 Publication Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 87 Issue (down) 9 Pages 092003 - 20pp  
  Keywords  
  Abstract T2K has performed the first measurement of nu(mu) inclusive charged current interactions on carbon at neutrino energies of similar to 1 GeV where the measurement is reported as a flux-averaged double differential cross section in muon momentum and angle. The flux is predicted by the beam Monte Carlo and external data, including the results from the NA61/SHINE experiment. The data used for this measurement were taken in 2010 and 2011, with a total of 10.8 x 10(19) protons-on-target. The analysis is performed on 4485 inclusive charged current interaction candidates selected in the most upstream fine-grained scintillator detector of the near detector. The flux-averaged total cross section is <sigma(CC)>(phi) = (6.91 +/- 0.13(stat) +/- 0.84(syst)) x 10(-39) cm(2)/nucleon for a mean neutrino energy of 0.85 GeV.

  Title Low-lying even parity meson resonances and spin-flavor symmetry revisited Type Journal Article
  Year 2013 Publication Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 87 Issue (down) 9 Pages 096006 - 18pp  
  Keywords  
  Abstract We review and extend the model derived in Garcia-Recio et al. [Phys. Rev. D 83, 016007 (2011)] to address the dynamics of the low-lying even-parity meson resonances. This model is based on a coupled-channels spin-flavor extension of the chiralWeinberg-Tomozawa Lagrangian. This interaction is then used to study the S-wave meson-meson scattering involving members not only of the pi octet, but also of the rho nonet. In this work, we study in detail the structure of the SU(6)-symmetry-breaking contact terms that respect (or softly break) chiral symmetry. We derive the most general local (without involving derivatives) terms consistent with the chiral-symmetry-breaking pattern of QCD. After introducing sensible simplifications to reduce the large number of possible operators, we carry out a phenomenological discussion of the effects of these terms. We show how the inclusion of these pieces leads to an improvement of the description of the J(P) = 2(+) sector, without spoiling the main features of the predictions obtained in the original model in the JP = 0(+) and J(P) = 1(+) sectors. In particular, we find a significantly better description of the I-G(J(PC)) =0(+)(2(++)), 1(-)(2(++)) and the I(JP)=1/2(2(+)) sectors, which correspond to the f(2)(1270), a(2)(1320), and K-2(*)(1430) quantum numbers, respectively.

  Title Study of the decay (B)over-bar(0) -> Lambda(+)(c) (p)over-bar pi(+) pi(-) and its intermediate states Type Journal Article
  Year 2013 Publication Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 87 Issue (down) 9 Pages 092004 - 17pp  
  Keywords  
  Abstract We study the decay (B) over bar (0) -> Lambda(+)(c) (p) over bar pi(+) pi(-), reconstructing the Lambda(+)(c) baryon in the pK(-) pi(+) mode, using a data sample of 467 X 10(6) B (B) over bar pairs collected with the BABAR detector at the PEP-II storage rings at SLAC. We measure branching fractions for decays with intermediate Sigma(c) baryons to be B[(B) over bar (0) -> Sigma(c)(2455)(++) (p) over bar (-) pi(-)] = (21.3 +/- 1.0 +/- 1.0 +/- 5.5) X 10(-5), B[(B) over bar (0) -> Sigma(c)(2520)(++) (p) over bar (-) pi(-)] = (11.5 +/- 1.0 +/- 0.5 +/- 3.0) X 10(-5), B[(B) over bar (0) -> Sigma(c)(2455)(0) (p) over bar (-) pi(-)] – (9.1 +/- 0.7 +/- 0.4 +/- 2.4) X 10(-5), and B[(B) over bar (0) -> Sigma(c)(2520)(++) (p) over bar (-) pi(-)] – (2.2 +/- 0.7 +/- 0.1 +/- 0.6) X 10(-5), where the uncertainties are statistical, systematic, and due to the uncertainty on the Lambda(+)(c) -> pK(-) pi(+) branching fraction, respectively. For decays without Sigma(c)(2455) or Sigma(c)(2520) resonances, we measure B[(B) over bar (0) -> Lambda(+)(c) (p) over bar pi(+) pi(-)](non-Sigma c) =(79 +/- 4 +/- 4 +/- 20) X 10(-5). The total branching fraction is determined to be B[(B) over bar (0) -> Lambda(+)(c) (p) over bar pi(+) pi(-)](total) = (123 +/- 5 +/- 7 +/- 32) X 10(-5). We examine multibody mass combinations in the resonant three-particle Sigma(c) final states and in the four-particle Lambda(+)(c) (p) over bar pi(+) pi(-) final state, and observe different characteristics for the (p) over bar pi combination in neutral versus doubly charged Sigma(c) decays.
