    • Fredholm approximants for potential scattering

      M L Sharma D Bondyopadhyay

      More Details Abstract Fulltext PDF

      An approximate method based on Fredholm approximants is used to solve Lippmann-Schwinger equation fors-andp-wave Yukawa ands-wave exponential potential scattering problems. The method is then applied to a problem ofπ-π scattering i nvolving the use of a well known equivalent potential. The equation for partial wave amplitudes is solved to generate the first threeπ-π resonances,ρ, f0, andg, in a self-consistent manner.

    • Recombination model for hadron production

      More Details Abstract Fulltext PDF

      We calculate baryon distributions in the fragmentation region ofpp collision using Das and Hwa picture of quark recombination. A new estimation of the sea quark distributions in proton is obtained by fitting the pseudoscalar meson data at fixedPT taking account of parton transverse momenta.
