I will review the calculation of the SUSY-QCD two-loop corrections to the strange and bottom Yukawa couplings in the MSSM. They include the resummation of the dominant corrections for large values of tan(beta), as well as the subleading terms induced by the trilinear Higgs couplings A_b,s. The phenomenological impact of the calculation will also be discussed.
We calculate quark and gluon jet fraction in multi-jet final states at the LHC, which is based on perturbative QCD at next-to-double logarithmic accuracy. We find a measurable scaling pattern of the fraction. This is related to a performance of new physics searches using quark-gluon jet discrimination in multi-jet final states, and would be useful for more understanding of QCD and tuning of...
We present the renormalization of the munuSSM and its application to higher-order corrections in the scalar sector. We show the phenomenological relevance of these higher-order calculations and compare with the corresponding results in the NMSSM.
Although deep learning might appear as a magic black box one only needs to throw data at to receive a solution, the practical reality is always different and often difficult. This talk shall guide through an example for the process of constructing an AI for predicting a physical quantity, namely the pMSSM-19 NLO electroweakino production cross-section at the LHC for 13 TeV. Naively, one could...
Phenomenological studies of SUSY models typically imply the sampling of multidimensional parameter spaces. Each parameter point needs to be checked against the available theoretical and experimental limits from indirect and direct SUSY searches. The constraints from electroweakino searches are particularly challenging due to the computational resources needed to calculate their production...
We make use of the recently released threshold-resummation improved PDF sets to consistently calculate theoretical predictions for slepton pair production and electroweakinos associated production at NLO+NLL accuracy. The updated cross sections have been carried out for the ongoing Run-II of the LHC and for the relevant processes that are considered in experimental searches. We study the cases...
In this talk, the status of the predictions for the partial decay widths of different more or less exotic Higgs bosons, i.e. SM-like Higgs bosons in extensions of the Standard Model as well as additional neutral or charged Higgs bosons, will be discussed. I will comment on different possible parameter definitions and the resulting consequences. In particular, I will report on recent results...
I will review recent progress in the calculation of the Higgs masses in various MSSM scenarios with heavy superparticles. I will describe advances in the calculation of the matching conditions for the couplings of the EFT valid below the SUSY scale, in the combination of the resummed logarithmic corrections obtained in the EFT approach with the existing fixed-order calculations of the Higgs...
The discovery of the Higgs boson with a mass of 125.09 GeV significantly constrains the allowed parameter space of the many SUSY models that predict the mass of the lightest Higgs boson to be of the order of the Z mass at tree-level. In these models, among which the MSSM is probably the most studied, large loop corrections are necessary to obtain a light Higgs boson mass compatible with the...
The non-observation of superpartners at the LHC coupled with a measured mass of the Higgs boson of $\sim125$ GeV, which points to relatively heavy spectra, has renewed the interest in the study of SUSY scenarios where most/all superpartners lie significantly above the EW scale. In this context an Effective Field Theory (EFT) approach to the Higgs mass computation is needed, in order to...
SUSY continues to elude direct searches at Run 2 of the LHC. Hence, indirect probes like electroweak precision observables are relevant to explore the parameter space of a model. The mass of W boson is such an observable where the LHC experiments are on their way improve on the uncertainties of the experimental result. The prediction for $M_W$ has been studied in depth in the MSSM and NMSSM....
