SUSY暗物质和LHC

SUSY dark matter and the LHC

Howard Baer

摘要:

弱尺度超对称性是标准模型的一个非常有意义的扩展,它有很强的数据支持。它提供了几个可行的暗物质候选者:最轻的中性伴子(WIMP),引力伴子和轴子/轴伴子超多重态。LHC即将启动在大型强子对撞机上发现的超对称性将大大有助于建立暗物质的性质。我提出的论点,为什么主要是轴子冷暗物质是一个更好的适合超对称模型比neutralinos。我还认为,基于SO(10)和混合轴子/轴子冷暗物质的汤川统一超对称大统一理论是非常令人信服的,并提出了在大型强子对撞机上产生胶子对的独特特征。

英文摘要:

Weak scale supersymmetry is a highly motivated extension of the Standard Model that has a strong degree of support from data. It provides several viable dark matter candidates: the lightest neutralino (a WIMP), the gravitino, and the axion/axino supermultiplet. The LHC turn-on is imminent. The discovery of supersymmetry at the LHC will go a long way towards establishing the nature of dark matter. I present arguments why mainly axion cold dark matter is a better fit for supersymmetric models than neutralinos. I also argue that Yukawa-unified SUSY GUT theories based on SO(10) with mixed axion/axino cold dark matter are extremely compelling, and present distinctive signatures for gluino pair production at the LHC.
