摘要:

在这些会议中,提出了一种新的方法来处理亮度测量中的光束诱导效应。基于Bhabha过程碰撞系的相对论运动学,束-束相关的不确定性可以降低到千分之一的水平,而与已知束参数的精度无关。具体的事件选择结合我们介绍的校正方法,导致系统的不确定性,从束流诱导效应是在几个千分之一的水平,在ILC的标称质心能量的80%以上的峰值区域。

英文摘要:

In these proceedings a novel approach to deal with the beam-induced effects in luminosity measurement is presented. Based on the relativistic kinematics of the collision frame of the Bhabha process, the beam-beam related uncertainties can be reduced to the permille level independently of a precision with which the beam parameters are known. Specific event selection combined with the corrective methods we introduce, leads to the systematic uncertainty from the beam-induced effects to be at a few permille level in the peak region above the 80% of the nominal centre-of-mass energies at ILC.
