摘要

以前曾提出过一个 "运行轴质量"（MArun）现象学模型，用于计算中微子和反中微子在原子核上的准弹性散射截面。它可以很容易地在中微子发生器中实现，而且只有两个自由参数，这两个参数是根据（反）中微子在各种核目标上的准弹性散射的总截面和微分截面的实验数据进行全局拟合得到的。在这项工作中，将 NOvA 近探测器关于μ介子中微子散射的总截面和微分截面的数据与使用 GENIE 中微子蒙特卡洛发生器（v.3.4.0）进行的模拟进行了比较，该发生器可选择使用 MArun 模型。

Test of the Model of “Running Axial Mass” Using NOvA Near Detector Data on Muon Neutrino Scattering on Nuclei

A phenomenological model of a “running axial mass” (MArun) was previously proposed to calculate cross sections for the quasielastic scattering of neutrinos and antineutrinos on nuclei. It can be easily implemented in neutrino generators and has only two free parameters, which are obtained from the global fit to the experimental data on the total and differential cross sections for the quasielastic scattering of (anti)neutrinos on various nuclear targets. In this work, the NOvA near detector data on the total and differential cross sections for the scattering of muon neutrinos, are compared to the simulation performed using the GENIE neutrino Monte Carlo generator (v.3.4.0), which optionally allows for using the MArun model.
