Heavy neutral fermions at the high-luminosity LHC
Journal of High Energy Physics, 2018 Long-lived light particles (LLLPs) appear in many extensions of the standard model. LLLPs are usually motivated by the observed small neutrino masses, by dark matter or both. Typical examples for fermionic LLLPs (a.k.a.

Gluino-SUGRA scenarios in light of FNAL muon g – 2 anomaly
Journal of High Energy Physics, 2021 Gluino-SUGRA ( g ~ $$ \overset{\sim }{g} $$ SUGRA), which is an economical extension of the predictive mSUGRA, adopts much heavier gluino mass parameter than other gauginos mass parameters and universal scalar mass parameter at the unification scale.

Open String Renormalization Group Flow as a Field Theory
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract This article shows that the integral flow‐lines of the RG‐flow of open string theory can be interpreted as the solitons of a Hořova–Lifshitz sigma‐model of open membranes. The authors argue that the effective background description of this model implies the g‐theorem of open string theory.

Threshold Corrections in the Exceptional Supersymmetric Standard Model [PDF]
, 2012 We calculate threshold corrections to the running gauge and Yukawa couplings in the Exceptional Supersymmetric Standard Model (E6SSM) and analyse the more precise and reliable mass spectra in a constrained model (CE6SSM).

Supersymmetric D-term Twin Higgs
Journal of High Energy Physics, 2017 We propose a new type of supersymmetric Twin Higgs model where the SU(4) invariant quartic term is provided by a D-term potential of a new U(1) gauge symmetry.

de Sitter State in Heterotic String Theory
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Supersymmetric Higgs singlet effects on FCNC observables
, 2008 Higgs singlet superfields, usually present in extensions of the Minimal Supersymmetric Standard Model (MSSM) which address the $\mu$-problem, such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and the Minimal Nonminimal Supersymmetric ...

Fixed points in supersymmetric extensions of the standard model
European Physical Journal C: Particles and Fields, 2022 We search for weakly interacting fixed points in extensions of the minimally supersymmetric standard model (MSSM). Necessary conditions lead to three distinct classes of anomaly-free extensions involving either new quark singlets, new quark doublets, or ...

Wegner estimate and upper bound on the eigenvalue condition number of non‐Hermitian random matrices
Communications on Pure and Applied Mathematics, Volume 77, Issue 9, Page 3785-3840, September 2024.Abstract We consider N×N$N\times N$ non‐Hermitian random matrices of the form X+A$X+A$, where A$A$ is a general deterministic matrix and NX$\sqrt {N}X$ consists of independent entries with zero mean, unit variance, and bounded densities. For this ensemble, we prove (i) a Wegner estimate, that is, that the local density of eigenvalues is bounded by N1+o(

b -> s gamma in the left-right supersymmetric model
, 2002 The rare decay $b \to s \gamma$ is studied in the left-right supersymmetric model. We give explicit expressions for all the amplitudes associated with the supersymmetric contributions coming from gluinos, charginos and neutralinos in the model to one ...
