1J/ψ-J/ψ scattering cross sections of quadratic and Cornell potentials显示文摘We study the scattering of J/ψ - J/ψ mesons using quadratic and Cornell potentials in our tetraquark(cccc)system.The system’s wavefunction in the restricted gluonic basis,which is written by utilizing the adiabatic approximation and Hamiltonian,is used via a quark potential model.The resonating group technique is used to obtain the integral equations,which are solved to obtain the unknown inter-cluster dependence of the total wavefunction of our tetraquark system.T-Matrix elements are calculated from the solutions,and eventually,the scattering cross sections are obtained using the two potentials.We compare these cross sections and find that the magnitudes of scattering cross sections of quadratic potential are higher than the Cornell potential.M.Imran Jamil SM.Sohail Gilani Ahmad Wasif Abdul Sattar Khan Ahmad Awan 2021Chinese Physics C2021,45,2:0
2D^0D^^0*(D^0D^0*) system in QCD-improved many body potential显示文摘For a system of current interest(composed of charm, anticharm and a pair of light quarks), we show trends in phenomenological implications of QCD-based improvements to a simple quark model treatment. We employ a resonating group method to render this difficult four-body problem manageable. We use a quadratic confinement so as to be able to improve beyond the Born approximation. We report the position of the pole corresponding to the D^0D^(0*) molecule for the best fit of a model parameter to the relevant QCD simulations. We point out the interesting possibility that the pole can be shifted to 3872 Me V by introducing another parameter I_0 that changes the strength of the interaction in this one component of X(3872). The revised value of this second parameter can guide future trends in modeling of the full exotic meson X(3872). We also report the changes with I_0 in the S-wave spin averaged cross sections for D^0D^(0*)-→ωJ/ψ and D^0D^(0*)-→ρJ/ψ. These cross sections are important regarding the study of QGP(quark gluon plasma).M.Imran Jamil Bilal Masud Faisal Akram S.M.Sohail Gilani 2017Chinese Physics C2017,41,1:0
