Content
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.
