gSeaGen: The KM3NeT GENIE-based code for neutrino telescopes

The gSeaGen code is a GENIE-based application developed to efficiently generate high statistics samples of events, induced by neutrino interactions, detectable in a neutrino telescope. The gSeaGen code is able to generate events induced by all neutrino flavours, considering topological differences between track-type and shower-like events. Neutrino interactions are simulated taking into account the density and the composition of the media surrounding the detector. The main features of gSeaGen are presented together with some examples of its application within the KM3NeT project.gSeaGen代码是一款基于GENIE的应用程序，旨在高效生成可在中微子望远镜中探测到的、由中微子相互作用诱发的高统计量事件样本。该代码可生成由所有中微子味诱发的事件，并兼顾径迹型与簇射型事件的拓扑差异。模拟中微子相互作用时，会充分考虑探测器周围介质的密度与组分。本文介绍了gSeaGen的主要特性，并展示了其在KM3NeT项目中的若干应用实例。
