A bstract The Minimal R-symmetric Supersymmetric Standard Model (MRSSM) is a well motivated BSM model which can accommodate the observed 125 GeV Higgs boson in agreement with electroweak precision observables, particular W mass and T parameter. In 2016 paper we showed that SM-like state be also realised as second-to-lightest scalar of MRSSM, leaving room for another sub-100 state. Motivated by recent ATLAS CMS observation di-photon excess at around 95 investigate possibility whether this...

In a recent paper we showed that the Minimal R-symmetric Supersymmetric Standard Model (MRSSM) can accommodate observed 125 GeV Higgs boson as lightest scalar of model in agreement with electroweak precision observables, particular W mass and T parameter. Here explore scenario light singlet (and bino-singlino) state which second-lightest takes role SM-like close to GeV. such case gets pushed up via mixing already at tree-level thereby reducing required loop correction. Unlike NMSSM, is...
The framework of trans-Planckian asymptotic safety has been shown to generate phenomenological predictions in the Standard Model and some its simple new physics extensions. A heuristic approach is often adopted, which bypasses functional renormalization group by relying on a parametric description quantum gravity with universal coefficients that are eventually obtained from low-energy observations. Within this few simplifying approximations typically introduced, including computation matter...

We perform threshold resummation soft gluon corrections to total cross sections squark-(anti)squark pairs framework. carried...

In view of lack the direct experimental evidence for a Beyond Standard Model (BSM) physics, accommodating SM-like Higgs boson is on most important constraints that BSM model must fulfill. Already some time FlexibleSUSY spectrum generator allowed reliable prediction masses and decay patterns in large class user defined supersymmetric non-supersymmetric models. However, no easy way to compare those predictions with data existed. To end we present here an interface between HiggsTools, computer...
