Rafal Maciula, Roman Pasechnik, Antoni Szczurek

摘要:

计算了质子-质子和质子-反质子碰撞中双衍射(EDD)产生开粲的微分截面。EDD的贡献约占开放魅力产生的总截面的1%。一些微分分布示出和讨论。EDD的贡献下降更快的$c$夸克/反夸克的横动量和$c \bar c$不变质量比在包容的情况下。

英文摘要:

We calculate differential cross sections for exclusive double diffractive (EDD) production of open charm in proton-proton and proton-antiproton collisions. Sizeable cross sections are found. The EDD contribution constitutes about 1 % of the total inclusive cross section for open charm production. A few differential distributions are shown and discussed. The EDD contribution falls faster both with transverse momentum of the $c$ quark/antiquark and the $c \bar c$ invariant mass than in the inclusive case.
