Muon g − 2 vs LHC Run 2 in supersymmetric models

open access: yesJournal of High Energy Physics, 2020
Supersymmetric models with sub-TeV charginos and sleptons have been a candidate for the origin of the long-standing discrepancy in the muon anomalous magnetic moment (g − 2). By gathering all the available LHC Run 2 results, we investigate the latest LHC

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

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-sneutrino production in electron-photon collisions [PDF]

open access: yesPhysical Review D, 1997
We study the production of charginos and sneutrinos in electron-photon collisions within the minimal supersymmetric standard model (MSSM). The high energy photons can be generated by Compton backscattering of intense laser pulses off one of the beams of the Next Linear Collider (NLC).

Search for disappearing tracks in proton-proton collisions at s=13TeV

open access: yesPhysics Letters B, 2020
A search is presented for long-lived charged particles that decay within the volume of the silicon tracker of the CMS experiment. Such particles can produce events with an isolated track that is missing hits in the outermost layers of the silicon tracker,

Search for Chargino and Neutralino Production at sqrt(s) = 192-209 GeV at LEP [PDF]

open access: yes, 2002
Approximately 438 pb-1 of e+e- data from the OPAL detector, taken with the LEP collider running at centre-of-mass energies of 192-209 Gev, are analyzed to search for evidence of chargino pair production, e+e- -> tilde chi^+_1 tilde chi^-_1, or neutralino

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).

Muon anomalous magnetic dipole moment in supersymmetric theories [PDF]

open access: yes, 2001
We study the muon anomalous magnetic dipole moment in supersymmetric theories. The impact of the recent Brookhaven E821 experimental measurement on both model-independent and model-dependent supersymmetric parameter spaces is discussed in detail. We find

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 ...

Combined search for electroweak production of charginos and neutralinos in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented. All searches use proton-proton collision data at s = 13 $$ \sqrt{s}=13 $$ TeV, recorded with the CMS detector at the LHC in 2016 and ...
