Production of Bc(1S) heavy meson in the Tevatron Run II and LHC with consideration of quark spin

Abstract

In this research, we have investigated the effect of spin orientation of quarks on the production of the Bc(1S) heavy mesons. We have calculated the fragmentation functions at initial scale µ° .Then we have modified to µ these fragmentation functions by using Altrali-Parisi equation. Also, we have calculated the transverse momentum distributions of the differential cross sections . Our results are in agreement with the experimental data for Tevatron Run II.
