Closing in on the chargino contribution to the muon g − 2 in the MSSM: Current LHC constraints [PDF]

open access: yes, 2017
We revisit the current LHC constraints on the electroweak-ino sector parameters in the minimal supersymmetric standard model (MSSM) that are relevant to explaining the $(g\ensuremath{-}2{)}_{\ensuremath{\mu}}$ anomaly via the dominant chargino and muon ...

Revisiting the exclusion limits from direct chargino-neutralino production at the LHC [PDF]

open access: yes, 2016
We revisit the existing limits on the gaugino masses in various supersymmetric (SUSY) scenarios derived from Run-I data of the LHC. These limits obtained from the various final states rely heavily on the simplified assumptions regarding the masses ...

Searches for pair production of charginos and top squarks in final states with two oppositely charged leptons in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search for pair production of supersymmetric particles in events with two oppositely charged leptons (electrons or muons) and missing transverse momentum is reported. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton

One-loop renormalisation of the NMSSM in SloopS : 1. the neutralino-chargino and sfermion sectors [PDF]

open access: yes, 2016
We have completed the one-loop renormalisation of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) allowing for and comparing between different renormalisation schemes. A special attention is paid to on-shell schemes. We study a variety of these

The Discreet Charm of Higgsino Dark Matter: A Pocket Review

open access: yesAdvances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
We give a brief review of the current constraints and prospects for detection of higgsino dark matter in low‐scale supersymmetry. In the first part we argue, after performing a survey of all potential dark matter particles in the MSSM, that the (nearly) pure higgsino is the only candidate emerging virtually unscathed from the wealth of observational ...

Chargino Production at LEP2 in a Supergravity Model [PDF]

open access: yes, 1996
In the framework of a particular supergravity model which provides a natural solution to the $\mu$--problem we show how the discovery of a chargino at LEP2 and the measurement of its mass and production cross--section, together with the measurement of ...

MSSM Dark Matter in Light of Higgs and LUX Results

open access: yesAdvances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016
The constraints imposed on the Minimal Supersymmetric Standard Model (MSSM) parameter space by the Large Hadron Collider (LHC) Higgs mass limit and gluino mass lower bound are revisited. We also analyze the thermal relic abundance of lightest neutralino, which is the Lightest Supersymmetric Particle (LSP).

Search for Charginos with a Small Mass Difference with the Lightest Supersymmetric Particle at \sqrt{s} = 189 GeV [PDF]

open access: yes, 2000
A search for charginos nearly mass-degenerate with the lightest supersymmetric particle is performed using the 176 pb^-1 of data collected at 189 GeV in 1998 with the L3 detector.

Two Higgs Bosons near 125 GeV in the Complex NMSSM and the LHC Run I Data

open access: yesAdvances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
We analyse the impact of explicit CP‐violation in the Higgs sector of the Next‐to‐Minimal Supersymmetric Standard Model (NMSSM) on its consistency with the Higgs boson data from the Large Hadron Collider (LHC). Through detailed scans of the parameter space of the complex NMSSM for certain fixed values of one of its CP‐violating (CPV) phases, we obtain ...

R--Parity Violating Signals for Chargino Production at LEP II [PDF]

open access: yes, 1998
We study chargino pair production at LEP II in supersymmetric models with spontaneously broken R-parity. We perform signal and background analyses, showing that a large region of the parameter space of these models can be probed through chargino searches
