Hai Tao Li, Ze Long Liu, Ivan Vitev

摘要:

未来电子-离子对撞机物理计划的一个重要部分是了解强子化的性质以及大核中能量和物质的传输。深度非弹性散射中的开放重味产生为解决这些关键问题提供了新的工具。本文首次计算了电子-核碰撞中D介子和B介子的碰撞截面,同时考虑了次主导阶QCD修正和冷核物质效应。我们的形式主义采用广义DGstrom演化,包括在介质中的部分子阵雨的贡献,是基于软共线有效理论与Glauber胶子,描述包容性的强子生产与核子和原子核的反应中开发的方法。这里总结的综合研究使我们能够确定最佳的可观测量,质心能量和运动学区域最敏感的物理能量损失和强子化在EIC。

英文摘要:

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.
