Search for supersymmetry using Higgs boson to diphoton decays at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2019
A search for supersymmetry (SUSY) is presented where at least one Higgs boson is produced and decays to two photons in the decay chains of pair-produced SUSY particles.

Search for Pair Production of Supersymmetric Top Quarks Mimicking Standard Model Top Event Signatures at CDF [PDF]

open access: yes, 2008
We present results of the search for the super-symmetric partner of the top quark, the stop quark, decaying to a b-quark and chargino with the subsequent chargino decay into a neutralino, lepton and neutrino.

CP violation at one loop in the polarization-independent chargino production in e+e- collisions

open access: yes, 2007
Recently Osland and Vereshagin noticed, based on sample calculations of some box diagrams, that in unpolarised e+e- collisions CP-odd effects in the non-diagonal chargino-pair production process are generated at one-loop.

Dark Matter: A Primer

open access: yesAdvances in Astronomy, Volume 2011, Issue 1, 2011., 2011
Dark matter is one of the greatest unsolved mysteries in cosmology at the present time. About 80% of the Universe′s gravitating matter is nonluminous, and its nature and distribution are for the most part unknown. In this paper, we will outline the history, astrophysical evidence, candidates, and detection methods of dark matter, with the goal to give ...

Probing heavy charged fermions at e + e − collider using the optimal observable technique

open access: yesJournal of High Energy Physics, 2022
In this work we study the production of color-neutral and singly-charged heavy leptons at the proposed International Linear Collider. We use the optimal observable technique to determine the statistical accuracy to which the coupling of such fermions to ...

Muon g−2 in MSSM gauge mediation revisited

open access: yesPhysics Letters B, 2017
The Higgs boson of 125 GeV requires large stop masses, leading to the large μ-parameter in most cases of gauge mediation. On the other hand, the explanation for the muon g−2 anomaly needs small slepton and neutralino/chargino masses.

SUSY Decays of Higgs Particles [PDF]

open access: yes, 1996
Among the possible decay modes of Higgs particles into supersymmetric states, neutralino and chargino decays play a prominent r\^ole. The experimental opportunities of observing such decay modes at LEP2 and at future e+e- linear colliders are analyzed ...

Search for supersymmetry in events with a τ lepton pair and missing transverse momentum in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search for the electroweak production of supersymmetric particles in proton-proton collisions at a center-of-mass energy of 13 TeV is presented in final states with a τ lepton pair.

New Precision Electroweak Tests in Supergravity Models [PDF]

open access: yes, 1997
We update the analysis of the precision electroweak tests in terms of 4 epsilon parameters, $\epsilon_{1,2,3,b}$, to obtain more accurate experimental values of them by taking into account the new LEP data released at the 28th ICHEP (1996, Poland).
