高尺度超对称性中$R$ -宇称破坏的极限

Limits on $R$-parity Violation in High Scale Supersymmetry

摘要:

我们重新讨论了最小超对称标准模型中$R$ -宇称破坏的极限。特别是,我们专注于高尺度的超对称性的情况下,所有的超粒子都超过约$10^{13}$ GeV的暴胀规模,因此没有超粒子进入热平衡。在这种情况下,宇宙学的极限,源于保存重子的不对称性,以前已被应用于弱尺度超对称性,现在放松。我们认为,即使当sparticles从来没有在平衡,PDMATHAMM-宇称违反仍然是通过中微子和核子实验和/或坚持非零的$B-L$不对称性的保存通过高维运营商的约束。

英文摘要:

We revisit the limits on $R$-parity violation in the minimal supersymmetric standard model. In particular, we focus on the high-scale supersymmetry scenario in which all the sparticles are in excess of the inflationary scale of approximately $10^{13}$ GeV, and thus no sparticles ever come into thermal equilibrium. In this case the cosmological limits, stemming from the preservation of the baryon asymmetry that have been previously applied for weak scale supersymmetry, are now relaxed. We argue that even when sparticles are never in equilibrium, $R$-parity violation is still constrained via higher dimensional operators by neutrino and nucleon experiments and/or insisting on the preservation of a non-zero $B-L$ asymmetry.
