The Contribution Of The Decomposition Photon Process To The Production Of X_c,b（1⁺） Mesons From The Gluon Melting

Based on the theory of perturbation quantum chromodynamics,the contribution of decomposition photon process to the generation of x_c,b（1^＋）meson coming from gluon melting are calculated under the LHC（Large Hadron Collider）energy level of relativis-tic heavy ion collisions.The calculations include the direct gluon-gluon melting pro-cess（LO）during the early time of relativistic heavy ion collision,semi-elastic decompo-sition photon process and inelastic decomposition photon process.In the decomposition process of photons,the high-energy photons emitted by the incident nuclei（charged par-tons in the nucleus）fluctuates out the gluon which with the other gluon into the nucleus produces x_c,b（1^＋） meson through the gluon-gluon melting interaction.The numerical results show that,the calculated results of xc with s^1/2=7TeV p-p collision conform to the experiment data given by the ATALS Collaboration.Additionally,the contribution of the inelastic decomposition photon process to the generation of x meson is greater than that of the semi-elastic process,the photogenic process is in a secondary position compared to the direct melting of gluon,however,the contribution of decomposition photon process to the generation ofx meson is significant.
