在EIC上的衍射双射流光生

Diffractive dijet photoproduction at the EIC

V. Guzey, M. Klasen

摘要:

我们提出了第一个,详细的研究衍射双射流photoproduction在最近批准的电子离子对撞机(EIC)在BNL。除了建立各种光束类型,能量和运动学切割的运动学范围外,我们还在最重要的运动学变量中对QCD的次领先阶(NLO)进行了精确的预测。我们表明EIC将提供新的和更精确的信息的衍射部分子密度函数(PDF)的坡密子比以前在HERA获得,照亮了仍然有争议的机制,全球与。仅分辨光子因子分解破坏,并提供对全新量的访问,即核衍射PDF。

英文摘要:

We present a first, detailed study of diffractive dijet photoproduction at the recently approved electron-ion collider (EIC) at BNL. Apart from establishing the kinematic reaches for various beam types, energies and kinematic cuts, we make precise predictions at next-to-leading order (NLO) of QCD in the most important kinematic variables. We show that the EIC will provide new and more precise information on the diffractive parton density functions (PDFs) in the pomeron than previously obtained at HERA, illuminate the still disputed mechanism of global vs.\ only resolved-photon factorization breaking, and provide access to a completely new quantity, i.e. nuclear diffractive PDFs.
