A 125 GeV Higgs and Its Diphoton Signal in Different SUSY Models: A Mini Review

Advances in High Energy Physics, Volume 2012, Issue 1, 2012., 2012
In this paper we briefly review our recent studies on a 125 GeV Higgs and its diphoton signal rate in different low‐energy supersymmetric models, namely, the minimal supersymmetric standard model (MSSM), the next‐to‐minimal supersymmetric standard model (NMSSM), the nearly minimal supersymmetric standard model (nMSSM), and the constrained MSSM.

Generation mixing of sneutrinos in heavier chargino decay [PDF]

Journal of High Energy Physics, 2006
The heavier chargino decay could yield two charged leptons of different generations, owing to generation mixing of sneutrinos. We discuss the possibility of producing $e$ and $ $ through this process in near future collider experiments. The analyses are made systematically in the supersymmetric extension of the standard model without assuming a ...

Search for direct top squark pair production in final states with one electron or muon using 21 fb−1 of ATLAS data

EPJ Web of Conferences, 2013
This article presents latest results of the search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in √s = 8 TeV pp collisions using L=21 fb−1 of data recorded with the ATLAS detector at the ...

Explanation of electron and muon g − 2 anomalies in the MSSM

Journal of High Energy Physics, 2019
The current experimental values of anomalous magnetic moments of muon and electron deviate from the Standard Model predictions by few standard deviations, which might be a hint of new physics.

Contribution of Neutralino and Chargino to Diagonal Form Factor of Majorana Neutrino in the Minimal Supersymmetric Standard Model

Cumhuriyet Science Journal, 2023
In this study, we have calculated the diagonal form factor and charge radius of Majorana neutrinos in the Minimal Supersymmetry Standard Model (MSSM) using Feynman-'t Hooft gauge and dimensional regularization. From the obtained result of calculations,

Higgs Bosons Near 125 GeV in the NMSSM with Constraints at the GUT Scale

Advances in High Energy Physics, Volume 2012, Issue 1, 2012., 2012
We study the NMSSM with universal Susy breaking terms (besides the Higgs sector) at the GUT scale. Within this constrained parameter space, it is not difficult to find a Higgs boson with a mass of about 125 GeV and an enhanced cross‐section in the diphoton channel.

Supersymmetric interpretation of the muon g – 2 anomaly

Journal of High Energy Physics, 2021
The Fermilab Muon g − 2 collaboration recently announced the first result of measurement of the muon anomalous magnetic moment (g − 2), which confirmed the previous result at the Brookhaven National Laboratory and thus the discrepancy with its Standard ...

CP sensitive observables in chargino production and decay into a W boson

, 2004
We study CP sensitive observables in chargino production in electron-positron collisions with subsequent two-body decay of one chargino into a W boson. We identify the CP odd elements of the W boson density matrix and propose CP sensitive triple-product ...

Higgs Information and NMSSM at the Large Hadron Collider

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
Information theory has proven to be a worthwhile tool for investigating the implications of the Higgs sector in the Next‐to‐Minimal Supersymmetric Standard Model (NMSSM) using Higgs information at the Large Hadron Collider (LHC) assessed through the entropy constructed by means of the branching ratios of decay channels of the Higgs boson.
