H1 F2(x,Q**2)测量的辐射校正

Radiative Corrections for H1 F2(x,Q**2) Measurement

A. A. Akhundov

摘要:

对HERA H1实验低$x$区的QED辐射修正进行了数值研究。用TERAD 91程序计算了质子结构函数$F_2(x,Q^2)$在$x= 10^{-2} - 10^{-4}$和$ 5 GeV^2 < Q^2 < 80 GeV^2$范围内的辐射修正量。结果表明,在混合变量相空间的某些点上,辐射修正可能不小。

英文摘要:

The numerical study of QED radiative corrections in the low $x$ region for the H1 experiment at HERA was performed. The analytical program TERAD91 was used to get the size of the radiative corrections for the measurement of the proton structure function $F_2(x,Q^2)$ in the range $x= 10^{-2} - 10^{-4}$ and $ 5 GeV^2 < Q^2 < 80 GeV^2$. It was found that radiative corrections can be not small in some points of the phase space of the mixed variables.
