关联产生中的重夸克质量效应

Heavy quark mass effects in associated production

Davide Napoletano

摘要:

在关联产生中涉及重夸克的过程,通常用两种因式分解方案来描述:一种是将重夸克视为无限大质量的物体,与QCD演化解耦,另一种是将其与轻夸克相同。这两种方法的不同之处仅在于包含了质量抑制项或重申了某一类矩阵。鉴于最近的结果,在这次演讲中,我们提出了最近的事态发展,扩展的现象学计划,试图将最好的两个世界,\NLO在蒙特卡罗事件生成。

英文摘要:

Processes involving heavy quarks in associated production, are usually described in two factorisation schemes: one in which the heavy quark is treated as an infinitely massive object, decoupled from QCD evolution, and one in which it is treated on the same footing of a light quark. These two approaches only differ by the inclusion of mass suppressed terms or in the resummation of a certain class of logarithms. In view of recent results, in this talk, we present recent developments that extend a phenomenological scheme, that tries to incorporate the best of both worlds, to \NLO in Monte Carlo event generation.
