LHCb束气成像结果

LHCb Beam-Gas Imaging Results

P. Hopchev

摘要:

LHCb顶点探测器的高分辨率使得能够对束-气体和束-束相互作用的顶点进行精确测量,并允许确定位置、角度和宽度等束参数。利用直接测量的束流特性,将束气成像方法应用于LHCb绝对光度测量。在这篇文章中,我们简要介绍了方法和2010年5月的数据获得的初步结果。

英文摘要:

The high resolution of the LHCb vertex detector makes it possible to perform precise measurements of vertices of beam-gas and beam-beam interactions and allows beam parameters such as positions, angles and widths to be determined. Using the directly measured beam properties the novel beam-gas imaging method is applied in LHCb for absolute luminosity determination. In this contribution we briefly describe the method and the preliminary results obtained with May 2010 data.
