论文摘要
未来电子离子对撞机的物理计划的重要组成部分是了解大核中的强环化和能量和物质的运输。深度非弹性散射中的开放风味产生为解决这些关键问题提供了一种新工具。我们通过在EIC的电子核碰撞中进行了首次计算D-Meson和B-Meson横截面，这是通过包括近代领先的QCD校正和冷核物质效应。我们的形式主义采用广义的DGLAP进化来包括中等内顿阵雨的贡献，并基于在软共线有效理论中开发的方法，其glauber胶子描述了与核子和核的反应中的包容性强子产生的方法。此处总结的综合研究使我们能够确定对EIC的能量损失和强发化物理学最敏感的最佳可观测物，质量中心的能量和运动区域。
An important part of the physics program at the future electron-ion collider is to understand the nature of hadronization and the transport of energy and matter in large nuclei. Open heavy flavor production in deep inelastic scattering provides a new tool to address these critical questions. We present the first calculation of D-mesons and B-meson cross sections in electron-nucleus collisions at the EIC by including both next-to-leading order QCD corrections and cold nuclear matter effects. Our formalism employs generalized DGLAP evolution to include the contribution of in-medium parton showers, and is based on methods developed in soft-collinear effective theory with Glauber gluons that describe inclusive hadron production in reactions with nucleons and nuclei. The comprehensive study summarized here allows us to identify the optimal observables, center-of-mass energies, and kinematic regions most sensitive to the physics of energy loss and hadronization at the EIC.
