论文摘要
半可见的喷气机出现在强烈相互作用的黑暗部门中，其中Parton Evolution包括黑暗扇形排放，导致喷气机与缺失的横向动量重叠。半可见喷气机的实现是使用毕达斯隐藏山谷模块来复制QCD扇区淋浴的。在这项工作中，已经检查了几种JET子结构，以比较半可见的喷气机和轻夸克/Gluon喷气机。这些比较是在半通用喷气机（信号）中使用不同的黑暗黑啤酒分数进行的。信号由完全暗的黑龙或可见的黑龙组成的极端情况提供了了解这些比较中使用的特定深色淋浴模型的效果。我们试图将由于固有的半可见射流特性引起的喷气叠加结构可观察到的行为，这是因为仅存在一个仅存在一个暗淋浴模型，如上所述。
Semi-visible jets arise in strongly interacting dark sectors, where parton evolution includes dark sector emissions, resulting in jets overlapping with missing transverse momentum. The implementation of semi-visible jets is done using the Pythia Hidden valley module to duplicate the QCD sector showering. In this work, several jet substructure observables have been examined to compare semi-visible jets and light quark/gluon jets. These comparisons were performed using different dark hadron fraction in the semi-visible jets (signal). The extreme scenarios where signal consists either of entirely dark hadrons or visible hadrons offers a chance to understand the effect of the specific dark shower model employed in these comparisons. We attempt to decouple the behaviour of jet-substructure observables due to inherent semi-visible jet properties, from model dependence owing to the existence of only one dark shower model as mentioned above.
