线性对撞机上双电荷Higgsinos粒子的单次产生

Single Production of Doubly Charged Higgsinos at linear e-e- colliders

Mariana Frank, Katri Huitu, Santosh Kumar Rai

摘要:

几个扩展的超对称模型,无论是由大统一,或中微子质量产生的动机,预测轻双电荷希格斯玻色子。本文研究了在国际直线对撞机(ILC)e-e-模式下,单个双电荷希格西诺的产生及其衰变通道。我们分析了e-e->波浪线{Delta}^{--}_{L,R} chi ^{0 - 1}的产生截面随不同运动学变量的变化,以及双电荷希格希格希我们包括标准模型的背景,并讨论如何运动削减可以有效地用于限制这种背景。这些奇异物质的单独产生可以为一种新的潜在对称性和超越最小超对称标准模型的物理学提供一个壮观的信号。

英文摘要:

Several extended supersymmetric models, motivated by either grand unification, or by neutrino mass generation, predict light doubly charged higgsinos. We study the production of a single doubly charged higgsino and its decay channels at the International Linear Collider (ILC) operating in the e-e- mode. We analyze the production cross section for e-e- --> tilde{Delta}^{--}_{L,R} chi^0_1 as a function of different kinematic variables, followed by the decay, through several channels, of the doubly charged higgsino into a final state of two leptons plus missing energy. We include the standard model background and discuss how kinematic cuts could be used effectively to limit this background. Single production of these exotics could provide a spectacular signal for a new underlying symmetry and for physics beyond the minimal supersymmetric standard model.
