在LHC和ILC上的多粒子SUSY模拟:离壳效应、干扰和辐射修正

Multiparticle SUSY simulations at LHC & ILC: Off-Shell effects, interferences and radiative corrections

Jurgen Reuter

摘要:

LHC和ILC中的超对称模型的有趣但困难的现象学需要相应的复杂性和成熟的模拟工具。这包括多粒子最终状态,可约和不可约背景,自旋相关性,光子和胶子的实际发射,虚拟校正等,其中大部分主题都包含在多粒子蒙特卡罗(MC)事件发生器Madgraph,WHIZARD和夏尔巴。显示了这些代码的比较,特别关注WHIZARD的新版本。我显示的例子,考虑全矩阵元素的必要性与所有的离壳效应和干扰的多粒子的最终状态在超对称模型,并给出了一个正在进行的项目的状态报告,在LHC的超对称过程模拟与这些代码,包括所有上述的更正。

英文摘要:

The interesting but difficult phenomenology of supersymmetric models at the LHC and ILC demands a corresponding complexity and maturity from simulation tools. This includes multi-particle final states, reducible and irreducible backgrounds, spin correlations, real emission of photons and gluons, virtual corrections etc. Most of these topics are included in the multi-particle Monte Carlo (MC) Event generators Madgraph, WHIZARD and Sherpa. A comparison of these codes is shown, with a special focus on the new release of WHIZARD. I show examples for the necessity of considering full matrix elements with all off-shell effects and interferences for multi-particle final states in supersymmetric models and give a status report on ongoing projects for simulations of SUSY processes at the LHC with these codes, including all of the abovementioned corrections.
