摘要:

本文讨论了多扇区规范介导的NMSSM的电弱对撞机签名。我们专注于生产的中性伴子和charginos级联衰变成标准模型粒子和更轻的超对称粒子,特别强调与多光子的最终状态。一个搜索策略的签名,至少有三个光子,并与目前的排除限制的基础上双光子搜索。我们表明,在许多地区的参数空间,我们的策略比现有的双光子分析这些模型提供了更强的约束。

英文摘要:

This paper discusses electroweak collider signatures of the NMSSM with multiple-sector gauge mediation. We focus on the production of neutralinos and charginos which cascade decay into standard model particles and lighter supersymmetric particles, with special emphasis on final states with multiple photons. A search strategy for signatures with at least three photons is presented and compared with current exclusion limits based on two-photon searches. We show that in many regions of the parameter space our strategy gives stronger constraints than the existing two-photon analysis for these models.
