QCD中多重软胶子交换的衍射深度非弹性散射

Diffractive deep inelastic scattering from multiple soft gluon exchange in QCD

Roman Pasechnik, Rikard Enberg, Gunnar Ingelman

摘要:

衍射硬散射被解释为新兴的高能夸克和核子的色场之间的软胶子交换的效果,导致整体色单重交换。将多个胶子交换求和到所有阶数导致幂和解析形式的振幅。数值计算再现了精确的HERA数据,并给出了质子胶子密度的新见解。

英文摘要:

Diffractive hard scattering is interpreted as the effect of soft gluon exchanges between the emerging energetic quarks and the nucleon's color field, resulting in an overall color singlet exchange. Summing multiple gluon exchanges to all orders leads to exponentiation and an amplitude in analytic form. Numerical evaluation reproduces the precise HERA data and gives new insights on the density of gluons in the proton.
