Low-energy lepton observables in the MRSSM

Presented by Dr. Hyejung STOECKINGER-KIM on 1 Jul 2019 from 17:20 to 17:40
Type: oral presentation
Track: Particle Physics Models of New Physics


In this talk we present the comprehensive numerical analyses and the analytic one-loop results for the low-energy observables, $(g-2) _\mu$, $\mu \to e \gamma$, and $\mu \to e$ conversion in the Minimal R-symmetric Supersymmetric Standard Model (MRSSM). The interplay between the three observables is investigated as well as the parameter regions with large $(g−2) _\mu$. A striking difference to the MSSM is the absence of $\tan\beta$ enhancements; however we find smaller enhancements governed by MRSSM-specific R-Higgsino couplings $\lambda _d$ and $\Lambda _d$. As a result we find significant contributions to $(g-2) _\mu$ only in a small parameter space with several SUSY masses below 200 GeV, compressed spectra and large $\lambda _d$, $\Lambda _d$. In this parameter space there is a correlation between all three considered observables. In the parameter region with small $(g-2) _\mu$ the SUSY masses can be larger and the correlation between $\mu \to e \gamma$ and $\mu \to e$ conversion is weak. Therefore already COMET Phase 1 has a promising sensitivity to the MRSSM. Ref.: arXiv:1902.06650 (submitted to JHEP)
