高能核子的GPD和弹性散射

GPDs of the nucleons and elastic scattering at high energies

O. V. Selyugin

摘要:

考虑到电磁和引力形状因子,从一组新的$t $相关的GPD计算,一个新的模型建立。强子振幅的实部只能通过复$s$确定。在这个模型的框架下,仅用$3$拟合高能参数,就可以定量描述$52.8 \leq \sqrt{s} \leq 1960 \ $ GeV的所有现有实验数据,包括库仑射程和大动量转移($0.0008 \leq |t| \leq 9.75 \ $ GeV $^2$).与TOTEM合作组在$7$ TeV能量下的初步数据进行了比较。

英文摘要:

Taking into account the electromagnetic and gravitational form factors, calculated from a new set of $t $-dependent GPDs, a new model is built. The real part of the hadronic amplitude is determined only through complex $s$. In the framework of this model the quantitative description of all existing experimental data at $52.8 \leq \sqrt{s} \leq 1960 \ $GeV, including the Coulomb range and large momentum transfers ($0.0008 \leq |t| \leq 9.75 \ $GeV$^2$), is obtained with only $3$ fitting high energy parameters. The comparison with the preliminary data of the TOTEM Collaboration at an energy of $7$ TeV is made.
