Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity

open access: yesFortschritte der Physik, Volume 72, Issue 4, April 2024.
Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar

Octonionic Magical Supergravity, Niemeier Lattices, and Exceptional & Hilbert Modular Forms

open access: yesFortschritte der Physik, Volume 72, Issue 2, February 2024.
Abstract The quantum degeneracies of Bogomolny‐Prasad‐Sommerfield (BPS) black holes of octonionic magical supergravity in five dimensions are studied. Quantum degeneracy is defined purely number theoretically as the number of distinct states in charge space with a given set of invariant labels.

IS (Low Energy) SUSY STILL ALIVE?

open access: yes, 2012
Supersymmetry, a new symmetry that relates bosons and fermions in particle physics, still escapes observation. Search for supersymmetry is one of the main aims of the Large Hadron Collider.

Light and compressed gluinos at the LHC via string theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In this article, we show that making global fits of string theory model parameters to data is an interesting mechanism for probing, mapping and forecasting connections of the theory to real world physics.

QCD corrections to the masses of the neutralCP-even Higgs bosons in the minimal supersymmetric standard model

open access: yes, 1998
We perform a diagrammatic calculation of the leading two-loop QCD corrections to the masses of the neutral CP-even Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM). The results are valid for arbitrary values of the parameters of the Higgs

Evolutionary Algorithms for Multi‐Center Solutions

open access: yesFortschritte der Physik, Volume 72, Issue 2, February 2024.
Abstract Large classes of multi‐center supergravity solutions have been constructed in the study of supersymmetric black holes and their microstates. Many smooth multi‐center solutions have the same charges as supersymmetric black holes, with all centers deep inside a long black‐hole‐like throat.

Muon anomalous magnetic moment in SUSY B−L model with inverse seesaw

open access: yesPhysics Letters B, 2016
Motivated by the tension between the Higgs mass and muon g−2 in minimal supersymmetric standard model (MSSM), we analyze the muon g−2 in supersymmetric B−L extension of the standard model (BLSSM) with inverse seesaw mechanism.

Constraining compressed versions of MUED and MSSM using soft tracks at the LHC

open access: yesJournal of High Energy Physics, 2017
A compressed spectrum is an anticipated hideout for many beyond standard model scenarios. Such a spectrum naturally arises in the minimal universal extra dimension framework and also in supersymmetric scenarios.

The SUSY Higgs Mass: the Singlet Saves the Day

open access: yes, 2010
We present a generalization of the Next-to-Minimal Supersymmetric Standard Model (NMSSM), with an explicit mu-term and a supersymmetric mass for the singlet superfield, as a route to alleviating the little hierarchy problem of the Minimal Supersymmetric ...

Triviality bounds in the next to minimal supersymmetric standard model [PDF]

open access: yesPhysical Review D, 1995
We study the implications of the triviality problem for the Higgs masses and other relevant parameters in the Next to Minimal Supersymmetric Standard Model (NMSSM). By means of triviality, a new way to constrain parameters is proposed, and therefore we are able to derive triviality bounds on the heaviest-Higgs mass, the lightest-Higgs mass, the soft ...
