LHC上p-p碰撞中J/Ψ粒子的产生与胶子分布函数
The production of J/Ψ in high energy collisions and the gluon density
摘要
Abstract
Using color evaporation model and color octet model we calculated the J/φ production cross section with respect to the possibly cms-energy in unpolarized p-p collisions on LHC. The production cross section was calculated respectively with three kinds of PDFs: CTEQ6, GRV98, and NpdfO4 under different production models. Our conclusion indicated that the cross section calculated with three kinds of PDFs are different more or less under high collision energy and the section calculated with different models is different. Compared them with the future LHC experiment data we can get further constraints on the nuclear gluon PDFs, which would be useful for studies of perturbative evolution on hadrons production.关键词
