摘要
研究了LHCPbPb过程CMS能量为6300AGeV条件下的光生J/ψ及Υ.结果表明,硬光生过程可以用于检验很多重要问题:如核中的股子分布;胶子和重夸克的J/ψ碎裂等。除此之外。
Hard photoproduction of J/ψ and Υ at LHC Pb-Pb collisions with CMS energy 6 300A GeV,is disscussed.It turns out that the hard photoproduction processes can be used to testing several important problems such as the gluon distribution in the nucleus,gluon and heavy quark fragmentation of J/ψ,et al..In addition the process also provide a new way of testing the EMC effects.
