MadGraph5_aMC@NLO中的非对称碰撞

Asymmetric collisions in MadGraph5_aMC@NLO

Laboni Manna, Anton Safronov, Carlo Flore, Daniel Kikola, Jean-Philippe Lansberg, Olivier Mattelaer

AI总结:

为支撑美国电子离子对撞机(EIC)的轻子-强子碰撞研究、精准控制辐射修正,研究团队扩展了MadGraph5_aMC@NLO框架的固定阶光生功能,使其可适配电子-强子、质子-核及核-核三类非对称碰撞场景。

摘要:

未来几年,美国电子离子对撞机(EIC)的轻子-强子碰撞研究将让我们以前所未有的高精度深入了解原子核的内部结构。要充分发挥EIC的作用、从各类测量中提取有价值信息,必须良好控制辐射修正。我们介绍了对MadGraph5_aMC@NLO(一款广泛用于大型强子对撞机(LHC)(次)领头阶计算的框架)中固定阶光生过程的扩展工作。该扩展既适用于准实光子来自电子的电子-强子碰撞,也适用于质子-原子核与原子核-原子核碰撞。

英文摘要:

We will gain unprecedented, high-accuracy insights into the internal structure of the atomic nucleus thanks to lepton-hadron collision studies in the coming years at the Electron-Ion-Collider (EIC) in the United States. A good control of radiative corrections is necessary for the EIC to be fully exploited and to extract valuable information from various measurements. We present our extension of photoproduction at fixed order in MadGraph5_aMC@NLO, a widely used framework for (next-to-)leading order calculations at the Large Hadron Collider (LHC). It applies to electron-hadron collisions, in which the quasi-real photon comes from an electron as well as to proton-nucleus and nucleus-nucleus collisions.
