High-Precision Calculations of the Higgs Boson Mass
Particles, 2022 In this paper, we review the status of the computations of the perturbative quantum corrections to the Higgs boson mass in the Standard Model and in its supersymmetric extensions. In particular, supersymmetric theories require a very accurate computation

Vojnotehnički Glasnik, 2023 Introduction/purpose: Supersymmetry is a symmetry of the Lagrangian that goes beyond Lie groups. It allows the exchange of bosons and fermions. The most important model is the Minimal Supersymmetric Standard Model, or MSSM.

Restrictions on the parameters of the Minimal Supersymmetric Standard Model with CP-violation [PDF]
EPJ Web of Conferences, 2019 The minimal supersymmetric extension of the standard model with CP-violation is considered in this paper. The main area of the model parameters, which is attractive for researchers, corresponds to small values of the tangent mixing angle of two doublets ...

Universe, 2022 Supersymmetry is a well-motivated theory for physics beyond the Standard Model. In particular, supersymmetric models can naturally possess dark matter candidates that can give rise to the measured dark matter content of the universe.

Standard model from a supergravity model with a naturally small cosmological constant
Journal of High Energy Physics, 2021 Guided by the naturalness criterion for an exponentially small cosmological constant, we present a string theory motivated 4-dimensional N $$ \mathcal{N} $$ = 1 non-linear supergravity model (or its linear version with a nilpotent superfield) with ...

The Higgs boson mass as fundamental parameter of the minimal supersymmetric standard model
European Physical Journal C: Particles and Fields, 2022 In the Minimal Supersymmetric Standard Model (MSSM) the mass of the lightest neutral Higgs boson is determined by the supersymmetric parameters. In the $$m_h$$ m h MSSM the precisely measured Higgs boson replaces the trilinear coupling $$A_t$$ A t as ...

A Concise Review on Some Higgs-Related New Physics Models in Light of Current Experiments
Universe, 2023 The Higgs boson may serve as a portal to new physics beyond the standard model (BSM), which is implied by the theoretical naturalness or experimental anomalies. This review aims to briefly survey some typical Higgs-related BSM models.

Resurgence of a de Sitter Glauber‐Sudarshan State: Nodal Diagrams and Borel Resummation
Fortschritte der Physik, Volume 71, Issue 12, December 2023., 2023 Abstract It is shown in this article that an explicit construction of a four‐dimensional de Sitter space may be performed using a diagrammatic approach via nodal diagrams emanating from the path integral representation of the Glauber‐Sudarshan state. Sum of these diagrams typically leads to an asymptotic series of Gevrey kind which can then be Borel ...

Explaining (g − 2) μ with multi-TeV sleptons
Journal of High Energy Physics, 2021 We present a supersymmetric extension of the Standard Model in which the new physics contributions to the anomalous magnetic moment of the muon can be more than an order of magnitude larger than in the minimal supersymmetric Standard Model.
