论文摘要
我们研究了未来电子离子对撞机（EIC）数据对标准模型有效现场理论（SMEFT）中探测四效算子的潜力。在EIC上使用偏振电子和质子束执行测量的能力提供了一种强大的工具，可以使不同的SMEFT操作员的效果分离。我们将EIC的潜在约束与从大型强子对撞机上的Drell-Yan数据获得的限制进行了比较。我们表明，EIC数据起着重要的互补作用，因为它可以通过可用的DRELL-YAN测量值探测Wilson系数的组合。
We study the potential of future Electron-Ion Collider (EIC) data to probe four-fermion operators in the Standard Model Effective Field Theory (SMEFT). The ability to perform measurements with both polarized electron and proton beams at the EIC provides a powerful tool that can disentangle the effects from different SMEFT operators. We compare the potential constraints from an EIC with those obtained from Drell-Yan data at the Large Hadron Collider. We show that EIC data plays an important complementary role since it probes combinations of Wilson coefficients not accessible through available Drell-Yan measurements.
