论文摘要
我们描述了Nuwro蒙特卡洛中微子事件发生器的扩展，并具有中性电子散射过程。这个新的动态通道包括带电的电流和中性电流交互以及它们的干扰，以$ν_\ ell e $和$ \barν_\ ell e $（$ \ ell = e，μ，μ，τ$）散射，从而产生十个可能的最终状态。我们在几个实例上说明了新功能的性能，包括对T2K $ν_μ\rightArrowν_e$振荡实验中背景的估计。我们表明，由中性电子相互作用引起的背景事件主要占据了相位空间的不同区域，并且很容易被分离。
We describe an extension of the NuWro Monte Carlo neutrino event generator with the neutrino-electron scattering processes. This new dynamical channel includes the charged current and neutral current interactions, together with their interference, for $ν_\ell e$ and $\barν_\ell e$ ($\ell=e,μ,τ$) scatterings, resulting in ten possible final states. We illustrate the performance of the new functionality on few physical examples, including an estimation of the background in the T2K $ν_μ\rightarrowν_e$ oscillation experiment. We show that the background events arising from the neutrino-electron interactions occupy mostly a distinct region of the phase space and can be easily separated.
