伽马 * 伽马 * 碰撞中的NLO BFKL

NLO BFKL in gamma* gamma* collisions

F. Caporale, D. Yu. Ivanov, A. Papa

摘要:

本文用BFKL方法研究了两个虚光子碰撞的强子总截面,其能量在LEP 2和未来直线对撞机的范围内。在BFKL格林函数中,BFKL重正化是在次前导阶进行的;光子影响因子是在前导阶进行的,但是包含了重正化尺度和BFKL尺度$s_0$变化下的不变性所需的子前导项。我们比较我们的结果与以前的估计基于类似的近似。

英文摘要:

We study in the BFKL approach the total hadronic cross section for the collision of two virtual photons for energies in the range of LEP2 and of future linear colliders. The BFKL resummation is done at the next-to-leading order in the BFKL Green's function; photon impact factors are taken instead at the leading order, but with the inclusion of the subleading terms required by invariance under changes of the renormalization scale and of the BFKL scale $s_0$. We compare our results with previous estimations based on a similar kind of approximation.
