    ρJ∕ψ Scattering in QCD using the Linear plus Columbic potential for tetra-quarks
    (UMT, Lahore, 2017) AWAIS AHMAD
    In this thesis the cross-sections for the process D^0 D ̅^0→ρ J/Ψ are calculated in the center of mass frame of reference. In this study we calculate the cross sections by taking four quark gluonic overlap factor f=1. Cornell potential for pairing interaction is used in this analysis. Resonating group method has been applied and kinetic energy, potential energy and overlap matrices have been written to construct the two coupled integral equations. Moreover, few approximations like Born approximation and adiabatic approximation have been employed to simplify the calculations. Total spin averaged cross sections are plotted versus total center of mass energies of the two incoming mesons for the given process.
