Search for disappearing tracks as a signature of new long-lived particles in proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. A disappearing track is an isolated track with missing hits in the outer layers of the silicon tracker, little or

Muon $$\mathbf {g-2}$$ g - 2 , neutralino dark matter and stau NLSP

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We explore the implications of resolving the muon $$g-2$$ g - 2 anomaly in a $$SU(4)_c \times SU(2)_L \times SU(2)_R$$ S U ( 4 ) c × S U ( 2 ) L × S U ( 2 ) R model, where the soft supersymmetry breaking scalar and gaugino masses break the left-right (LR)

Search for the lightest chargino at GeV [PDF]

open access: yesPhysics Letters B, 1996
A search for pair production of the lightest chargino at root-s = 130.4 and 136.3 GeV has been carried out using the data sample corresponding to the 5.92 pb(-1) recorded by the DELPHI detector dur ...

Supersymmetry spectroscopy in stop-chargino production at CERN LHC [PDF]

open access: yesPhysical Review D, 2006
We consider the process of associated stop-chargino production in the MSSM at LHC and show that, at the simplest Born level, the production rate is dramatically sensitive to the choice of the benchmark points, oscillating from potentially "visible" maxima of the picobarn size to much smaller, hardly "visible", values.

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 direct top squark pair production in final states with one isolated lepton using 21 fb−1 of data collected with the ATLAS detector

open access: yesEPJ Web of Conferences, 2014
Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the third generation quarks with masses not too far from those of their Standard Model counterparts. Top or bottom scalar quarks (or squarks) with masses less than a few

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in 21 fb−1 of pp collisions at √(s) = 8 TeV with the ATLAS detector

open access: yesEPJ Web of Conferences, 2013
A search for direct chargino and neutralino production processes is presented in a final state with exactly 3 leptons (electrons or muons). No excess over the Standard Model has been observed. The analysis presented is based on 20.7 fb−1 of proton-proton

Chargino and neutralino production at $$e^+e^-$$ e + e - colliders in the complex MSSM: a full one-loop analysis

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
For the search for charginos and neutralinos in the Minimal Supersymmetric Standard Model (MSSM) as well as for future precision analyses of these particles an accurate knowledge of their production and decay properties is mandatory.

Inclusive searches for SUSY from CMS

open access: yesEPJ Web of Conferences, 2014
Many searches for supersymmetry have been performed by the CMS collaboration at the LHC and in this document a selection of results of inclusive searches is presented.
