摘要

我们非常简要地描述了中微子核子反应中产生一个介子的“HNV”模型的主要成分，包括最新的修正。我们给出了在介子-核子质心测量的总横截面和介子角分布的结果。后者表明，在某些蒙特卡罗发生器中所做的取各向同性分布的近似在微观计算中是不支持的。在考虑相应介质效应的情况下，将该模型应用于一个核内介子的产生，并给出了一些初步结果。

One pion production in neutrino nucleon and neutrino nucleus interaction

We very briefly describe the main ingredients, including the latest modifications, of the ``HNV'' model for one pion production in neutrino nucleon reactions. We present results for total cross sections as well as pion angular distributions with respect to the pion polar angles measured in the pion-nucleon center of mass. The latter show that the approximation of taking an isotropic distribution, as done in some Monte Carlo generators, is not supported by microscopic calculations. With the corresponding medium effects taken into account, the model is applied to one pion production in nuclei for which we show some preliminary results.
