Supersymmetric naturalness beyond MSSM

open access: yesJournal of High Energy Physics, 2019
The experiments at the Large Hadron Collider (LHC) have pushed the limits on masses of supersymmetric particles beyond the ∼TeV scale. This compromises naturalness of the simplest supersymmetric extension of the Standard Model, the minimal supersymmetric

Anomaly induced inflation in the minimal quartic extension of Einstein’s gravity

open access: yesEuropean Physical Journal C: Particles and Fields
A particular extension of Einstein’s General Relativity up to and including quartic terms in the curvature tensor is minimal in the sense that it has a unique maximally symmetric vacuum and only a massless spin-2 excitation in its spectrum around the ...

Reduction of the parameters in MSSM

open access: yesJournal of High Energy Physics, 2018
In the present work we search for renormalization group invariant relations among the various massless and massive parameters of the Minimal Supersymmetric Standard Model.

Restrictions on Parameters of Minimal Supersymmetric Standard Model

open access: yesContemporary Mathematics. Fundamental Directions, 2018
Higgs boson with mass mh = 126 GeV was discovered at Large Hadron Collider in 2012. Its mass corresponds both to Standard Model of elementary-particles physics and to the mass of the most lightweight Higgs boson in the minimal supersymmetric Standard Model.

Statistical analysis of supersymmetric dark matter in the minimal supersymmetric standard model after WMAP

open access: yes, 2004
We study supersymmetric dark matter in the general flavor diagonal minimal supersymmetric standard model by means of an extensive random scan of its parameter space.

Implications of a stop sector signal at the LHC

open access: yesJournal of High Energy Physics, 2018
Naturalness arguments suggest that the stop sector is within reach of the Large Hadron Collider (LHC). We investigate how the observation of a third generation squark signal could predict masses and discovery modes of other supersymmetric particles, or ...

Squark production with R-symmetry beyond NLO at the LHC

open access: yesJournal of High Energy Physics
The Minimal R-symmetric Supersymmetric Standard Model (MRSSM) provides a realisation of supersymmetry in which the parameter space is less constrained by the current LHC data than in the simplest supersymmetric scenarios.

THE NEXT-TO-MINIMAL SUPERSYMMETRIC EXTENSION OF THE STANDARD MODEL REVIEWED [PDF]

open access: yesInternational Journal of Modern Physics A, 2010
The next-to-minimal supersymmetric extension of the Standard Model (NMSSM) is one of the most favored supersymmetric models. After an introduction to the model, the Higgs sector and the neutralino sector are discussed in detail. Theoretical, experimental, and cosmological constraints are studied.

SM and MSSM Higgs Boson Production: Spectra at large transverse Momentum

open access: yes, 2006
Strategies for Higgs boson searches require the knowledge of the total production cross section and the transverse momentum spectrum. The large transverse momentum spectrum of the Higgs boson produced in gluon fusion can be quite different in the ...

Seeking a coherent explanation of LHC excesses for compressed spectra

open access: yesEuropean Physical Journal C: Particles and Fields
The most recent searches by the ATLAS and CMS Collaborations in final states with soft leptons and missing transverse energy show mild excesses predominantly associated with dilepton invariant masses of about $$10{-}20$$ 10 - 20  GeV, which can result ...
