Ratio of Photoproduction Rates of $\jpsi$ and
J. P. Ma, Jia-Sheng Xu
There are different approaches for diffractive photoproduction of charmonia. Recently, a new approach is proposed, in which charm quarks are taken as heavy quarks and the nonpertur…
Soft Gluon Approach for Diffractive Photoproduction of J/psi
J. P. Ma, J. S. Xu
We study diffractive photoproduction of by taking the charm quark as a heavy quark. A description of nonperturbative effect related to can be made by using NRQCD. In th…
Exclusive Decay of Quarkonia and Meson into a Lepton Pair Combined with Two Pions
J. P. Ma, Jia-Sheng Xu
We study the exclusive decay of , and into a lepton pair combined with two pions in the two kinematic regions. One is specified by the two pions having large momenta…
Exclusive decay of heavy quarkonium into photon and two pions
J. P. Ma, Jia-Sheng Xu
We study the exclusive decay of heavy quarkonium into one photon and two pions in the kinematic region, where the two-pion system has a invariant mass which is much smalle…
Demonstration of the double Q^2-rescaling model
Hong-an Peng, Cong-feng Qiao, Jia-sheng Xu +1
In this paper we have demonstrated the double Q^2-rescaling model (DQ^2RM) of parton distribution functions of nucleon bounded in nucleus. With different x-region of l-A deep inela…
Associated jpsi + gamma diffractive production: the nature of Pomeron and test of hard diffractive factorization
Jia-Sheng Xu, Hong-An Peng
We present a study of diffractive associated jpsi + gamma production at the Fermilab Tevatron and LHC based on the Ingelman-Schlein model for hard diffractive scattering and the fa…
Production of glueball from double diffractive process in high energy collision
Hong-An Peng, Jia-Sheng Xu
Motivated by the recent experimental data about candidates for glueball from different processes, we discuss in this paper the production of 0^{++} glueball from double diffractive…
