摘要:

高精度HERA数据允许搜索TeV尺度的超越标准模型的贡献,电子夸克散射。在中性和带电电流$ep$散射对应的亮度约1 FB $^{-1}$的包容性深非弹性截面的组合测量已被用于本分析。提出了一种新的方法来超越标准模型分析的包容性$ep$的数据,同时拟合的部分子分布函数的贡献一起“新物理”的过程进行。结果考虑夸克形状因子模型内的夸克的有限半径。得到的95% C. L.有效夸克半径的上限是$0.43\cdot 10^{-16}$ cm。

英文摘要:

The high-precision HERA data allows searches up to TeV scales for Beyond the Standard Model contributions to electron-quark scattering. Combined measurements of the inclusive deep inelastic cross sections in neutral and charged current $ep$ scattering corresponding to a luminosity of around 1 fb$^{-1}$ have been used in this analysis. A new approach to the beyond the Standard Model analysis of the inclusive $ep$ data is presented; simultaneous fits of parton distribution functions together with contributions of "new physics" processes were performed. Results are presented considering a finite radius of quarks within the quark form-factor model. The resulting 95% C.L. upper limit on the effective quark radius is $0.43\cdot 10^{-16}$ cm.
