包括可能的R宇称破缺相互作用的μ-τ中微子折射的SUSY辐射修正

SUSY radiative corrections on mu-tau neutrino refraction including possible R-parity breaking interactions

J. Gava, C. -C. Jean-Louis

摘要:

本文研究了超对称模型中中微子折射率的单圈辐射修正。我们考虑了标准模型的次最小超对称扩展(NMSSM),由于理论和实验的原因,它恰好是一个比MSSM更好的超对称候选者。我们扫描相关的超对称性参数,并确定区域的参数空间中产生有趣的值为V_{mu tau}。如果R-宇称被破坏,则MSSM和NMSSM的贡献之间存在显着差异,这与R-宇称守恒的情况相反。最后,对于一个非零的CP破坏阶段,我们分析表明,V_{mu tau}的存在将明确意味着CP破坏效应的超新星电子(反)中微子通量。

英文摘要:

In this paper we investigate the one-loop radiative corrections to the neutrino indices of refraction from supersymmetric models. We consider the Next-to Minimal Supersymmetric extension of the Standard Model (NMSSM) which happens to be a better supersymmetric candidate than the MSSM for both theoretical and experimental reasons. We scan the relevant SUSY parameters and identify regions in the parameter space which yield interesting values for V_{mu tau}. If R-parity is broken there are significant differences between MSSM and NMSSM contributions contrary to the R-parity conserved case. Finally, for a non-zero CP-violating phase, we show analytically that the presence of V_{mu tau} will explicitly imply CP-violation effects on the supernova electron (anti-) neutrino fluxes.
