Title: Hadronic Physics Studies at BaBar

Abstract

A new resonance Y(4260) with a mass of 4259 {+-} 8{sub -6}{sup +2} MeV/c{sup 2} and J{sup PC} = 1{sup --}, discovered by the BaBar experiment shows peculiar behavior in his decay mode. The {Lambda}{sub c}{sup +} baryon mass has been measured, using its decays to {Lambda}K{sub S}{sup 0} K{sup +} and {Sigma}{sup 0}K{sub S}{sup 0}K{sup +}, and its value is 2286.46 {+-} 0.14 MeV/c{sup 2}, the precision is greatly improved w.r.t. PDG value. {Xi}{sub c}{sup 0} and {Omega}{sub c}{sup 0} decays and production have been studied with results greatly improved w.r.t. PDG.

  • We present new results on hadronic B and D decays from the BABAR experiment. The first part of this document presents searches for new channels which may be used for CP measurements. The second part is dedicated to hadronic decays with tests of QCD factorization predictions and other models for B structure and decay mechanisms. A new result on the reference branching ratio D{sub s}{sup +} {yields} {phi}{pi}{sup +} is also reported.
  • We present a selection of recent results from studies of rare hadronic B decays based on a sample of 232 million B{bar B} pairs, corresponding to an integrated luminosity of 211 fb{sup -1}, which were recorded with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage ring.
  • The University of Louisville High Energy Physics group has undertaken a long-term effort in understanding baryon production in elementary particle processes in the 10 GeV energy region. We have contributed significantly to the broad program of the BaBar Collaboration, particularly in support of computing, data visualization, and simulation. We report here on progress in the areas of service to the Collaboration and understanding of baryon production via measurement of inclusive hadronic particle spectra.
  • The University of Louisville High Energy Physics group contributed significantly to the success of the BaBar Experiment at SLAC and the Mu2e Experiment at Fermilab. In particular, they have contributed to understanding hadronic processes in electron-positron annihilation and charged lepton flavor violation in a very rare muon conversion process. Both are high-precision undertakings at the Intensity Frontier of High Energy Physics.
