We present an extension to the Mathematica package SARAH which allows for Higgs mass calculations at two-loop level in a wide range of supersymmetric models beyond MSSM. These are based on effective potential approach and include all corrections independent electroweak gauge couplings. For numerical evaluation Fortran code SPheno is generated by SARAH. This prediction more complicated SUSY with same precision that most state-of-the-art spectrum generators provide
Abstract Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions Standard Model, where they play crucial role in constraining parameter space. The discovery boson and remarkably precise measurement its mass at LHC have spurred new efforts aimed improving accuracy theoretical predictions models. “ Precision SUSY Mass Calculation Initiative ” (KUTS) was launched 2014 to provide forum discussions between different groups involved these efforts. This report aims...
We discuss the impact of two-loop corrections to Higgs mass in next-to-minimal supersymmetric standard model beyond $O({\ensuremath{\alpha}}_{S}({\ensuremath{\alpha}}_{b}+{\ensuremath{\alpha}}_{t}))$. For this purpose we use combination public tools sarah and SPheno include all contributions stemming from superpotential parameters. show that case a heavy singlet are often MSSM-like reduce predicted SM-like state by about 1 GeV as long $\ensuremath{\lambda}$ is moderately large. larger values...
We calculate the corrections to Higgs mass in general theories restricted case of massless gauge bosons (the gaugeless limit). present analytic expressions for two-loop tadpole diagrams, and corresponding zero-momentum limit self-energies, equivalent second derivative effective potential. describe implementation SARAH, which allows an efficient, accurate rapid evaluation generic theories. In appendix, we provide diagrams massive bosons.
The hints for a new resonance at 750 GeV from ATLAS and CMS have triggered significant amount of attention. Since the simplest extensions standard model cannot accommodate observation, many alternatives been considered to explain excess. Here we focus on several proposed renormalisable weakly-coupled models revisit results given in literature. We point out that physically important subtleties are often missed or neglected. To facilitate study excess created collection 40 files, selected...
Many extensions of the leptonic sector minimal supersymmetric standard model (MSSM) are known, most them leading to observable flavor violating effects. It has recently been shown that 1-loop contributions lepton three-body decays ${l}_{i}\ensuremath{\rightarrow}3{l}_{j}$ involving ${Z}^{0}$ boson may be dominant, is, much more important than usual photonic penguins. Other processes like $\ensuremath{\mu}$-$e$ conversion in nuclei and $\ensuremath{\tau}$ into mesons also enhanced by same...

We present a precise analysis of the Higgs mass corrections stemming from vectorlike top partners in supersymmetric models. reduce theoretical uncertainty compared to previous studies following aspects: (i) including one-loop threshold SM gauge and Yukawa couplings due presence new states obtain $$ \overline{\mathrm{DR}} parameters entering all loop calculations, (ii) full momentum dependence at one-loop, (iii) two-loop but ones involving g1 g2. find that additional are very important can...
The recent measurements of $B_s^0 \to \mu\bar{\mu}$ decay candidates at the LHC consistent with standard model rate, and improving upper limits for $B_d^0 can strongly constrain beyond physics. For example, in supersymmetric models broken R-parity (RpV), they restrict size new couplings. We use combination public software packages SARAH SPheno to derive bounds on several combinations violating improve existing couplings which open tree-level channels state induce loop contributions. This is...
We study the impact of large trilinear R-parity violating couplings on lightest CP-even Higgs boson mass in supersymmetric models. use publicly available computer codes SARAH and SPheno to compute leading two-loop corrections. effective potential approach. For not too heavy third generation squarks (< 1 TeV) close unitarity bound we find positive corrections up a few GeV mass.
Soft supersymmetry-breaking terms provide a wealth of new potential sources flavour violation, which are tightly constrained by precision experiments. This has posed challenge to construct models both explain the structure Standard Model Yukawa couplings and also predict soft-breaking patterns that compatible with these constraints. While such have been studied in great detail, impact violating soft on Higgs mass at two-loop level assumed be small or negligible. In this letter, we show large...
Searches at the Large Hadron Collider (LHC) for neutral, long-lived particles have historically relied on detection of displaced produced by their decay within detector volume. In this paper we study potential complementary signature comprising missing transverse energy (E miss ) signal, traditionally used to look dark matter, e.g., lightest supersymmetric particle (LSP), extend LHC coverage models with (LL) when they outside detector. Using CMS and ATLAS analyses 8 TeV LHC, set an upper...
