用OPERA探测器研究带电中微子-铅相互作用中的带电强子多重数

Study of charged hadron multiplicities in charged-current neutrino-lead interactions in the OPERA detector

OPERA Collaboration

摘要:

OPERA实验旨在通过直接观测CNGS中微子束中的τ中微子来寻找出现模式下的$ν_μ \rightarrow ν_τ$振荡。本文研究了铅中带电中微子相互作用产生的带电粒子多重数。给出了带电强子平均多重数及其色散,并研究了不同运动学区域的KNO标度。结果中详细的表格,可用于验证的中微子-铅相互作用的蒙特卡罗发电机的形式。

英文摘要:

The OPERA experiment was designed to search for $ν_μ \rightarrow ν_τ$ oscillations in appearance mode through the direct observation of tau neutrinos in the CNGS neutrino beam. In this paper, we report a study of the multiplicity of charged particles produced in charged-current neutrino interactions in lead. We present charged hadron average multiplicities, their dispersion and investigate the KNO scaling in different kinematical regions. The results are presented in detail in the form of tables that can be used in the validation of Monte Carlo generators of neutrino-lead interactions.
