Abstract

We propose a simple empirical model for evaluating the quasielastic neutrino- and antineutrino-nucleus cross sections, based on the conventional relativistic Fermi-gas model and the notion of running (dipole) axial-vector mass of the nucleon driven by two adjustable parameters (one of which is the ordinary axial mass of the nucleon). The suggested approach provides reasonable agreement with available consistent accelerator data on total, differential, and double differential quasielastic and quasielastic-like cross sections for different nuclear targets.

中微子和反中微子与核的准弹性相互作用的统一经验模型

摘要

我们基于传统的相对论费米气体模型和由两个可调参数驱动的核子运行（偶极）轴向矢量质量的概念，提出了一个简单的经验模型来评估准弹性中微子和反中微子核的截面其中是核子的普通轴向质量）。所建议的方法与可用的一致加速器数据在不同核目标的总，微分和双微分准弹性和类弹性横截面上具有合理的一致性。
