Soft Probes of SU(5) Unification

Ilia Gogoladze, Rizwan Khalid, Nobuchika Okada, Qaisar Shafi

摘要:

我们探讨了SU(5)启发的扩展的约束最小超对称标准模型(CMSSM)的sparticle和Higgs光谱。用m_{\bar 5}和m_{10}代替普适软参数m_0,其中m_{\bar 5}和m_{10}表示与SU(5)的五维和十维表示中的场相关的普适软标量质量。特殊情况m_{\bar 5} m_{10}产生一个相当特征的sparticle光谱,可以在大型强子对撞机上进行测试。我们强调了几个基准点,其中最轻的中性伴子饱和的WMAP约束冷暗物质丰度。

英文摘要:

We explore the sparticle and Higgs spectroscopy of an SU(5) inspired extension of the constrained minimal supersymmetric standard model (CMSSM). The universal soft parameter m_0 is replaced by m_{\bar 5} and m_{10}, where m_{\bar 5} and m_{10} denote universal soft scalar masses associated with fields in the five and ten dimensional representations of SU(5). The special case m_{\bar 5} << m_{10} yields a rather characteristic sparticle spectroscopy which can be tested at the LHC. We highlight a few benchmark points in which the lightest neutralino saturates the WMAP bound on cold dark matter abundance.
