论文摘要
拟议的高光度高能电子离子对撞机（EIC）将探索宽的Bjorken-X（$ x_ {bj} $）和$ q^{2} $相位空间中的质子/核结构。重型风味产物是在初始碰撞中产生的，并受到核培养基的影响。未来EIC的重型强体和喷气测量值将使我们能够更好地限制NPDF，尤其是在受约束较差的高$ x_ {Bj} $区域中，精确地确定了夸克/gluon碎片过程，并直接研究核介质内的夸克/gluon能量。这些测量值可以限制相对论重离子对撞机（RHIC）和大型强子对撞机（LHC）的先前和正在进行的重离子测量的冷核培养基效应。硅顶点/跟踪探测器对于实现EIC的重型风味和喷气测量至关重要。将讨论在未来EIC中对拟议的重风味和可观察到的探测器性能可观察到的可行性研究。
The proposed high luminosity high energy Electron-Ion Collider (EIC) will explore the proton/nuclear structure in a wide Bjorken-x ($x_{BJ}$) and $Q^{2}$ phase space. Heavy flavor products are generated in initial collisions and have their hadronization influenced by the nuclear medium. Heavy flavor hadron and jet measurements at the future EIC will allow us to better constrain the nPDFs especially in the poorly constrained high $x_{BJ}$ region, precisely determine the quark/gluon fragmentation processes and directly study the quark/gluon energy loss within the nuclear medium. These measurements can constrain the cold nuclear medium effects for previous and ongoing heavy ion measurements at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC). Silicon vertex/tracking detectors are essential to realize the heavy flavor and jet measurements at the EIC. Feasibility studies in simulation for proposed heavy flavor and jet observable with evaluated detector performance at the future EIC will be discussed.
