标题： Topological heavy-flavor tagging and intrinsic bottom at the Electron-Ion Collider

摘要： 重味强子产生，特别是底强子产生，在深度非弹性散射（DIS）实验中难以研究，这是由于产生率和分支比都很小。 为了克服这些限制，提出了一种基于事件顶点结构的识别重味DIS事件的方法。 基于为LHCb实验开发的重味喷注标记策略，该算法使用位移顶点来识别重味强子的衰变。 通过模拟展示了该算法在电子-离子对撞机上的性能，并表明它能够发现质子中非微扰内在底夸克的发现潜力。 显示英文摘要

摘要： Heavy-flavor hadron production, in particular bottom hadron production, is difficult to study in deep-inelastic scattering (DIS) experiments due to small production rates and branching fractions. To overcome these limitations, a method for identifying heavy-flavor DIS events based on event topology is proposed. Based on a heavy-flavor jet tagging strategy developed for the LHCb experiment, this algorithm uses displaced vertices to identify decays of heavy-flavor hadrons. The algorithm's performance at the Electron-Ion Collider is demonstrated using simulation, and it is shown to provide discovery potential for non-perturbative intrinsic bottom quarks in the proton.
