顶对和重玻色子末态模拟的最新进展

Latest developments in the simulation of final states involving top-pair and heavy bosons

Emanuele Re

摘要:

本文综述了近年来在顶夸克和矢量玻色子对末态模拟方面的进展。首先,我将讨论最近发现的解决方案,需要在NLO+PS精度下模拟完全差分顶对产生($pp\to b\bar{b}$ + 4轻子),精确地保留脱壳效应和干涉效应。在第二部分中,我将回顾MiNLO(多尺度改进的NLO)方法,然后展示最近的应用,即$W^+W^-$和$W^+W^- +$ 1喷流产生的同时NLO+PS描述。

英文摘要:

I give an overview of recent progress in the simulation of final states involving top-quarks and vector bosons pair. First I'll discuss the recently found solutions needed to simulate fully differential top pair production ($pp\to b\bar{b}$ + 4 leptons) at NLO+PS accuracy, retaining off-shellness and interference effects exactly. In the second part, I'll review the MiNLO (Multi-scale Improved NLO) method, and then show a recent application, namely the simultaneous NLO+PS description of $W^+W^-$ and $W^+W^- +$ 1 jet production.
