Machine-Learning Analysis of Radiative Decays to Dark Matter at the LHC

open access: yesJournal of High Energy Physics
The search for weakly interacting matter particles (WIMPs) is one of the main objectives of the High Luminosity Large Hadron Collider (HL-LHC). In this work we use Machine-Learning (ML) techniques to explore WIMP radiative decays into a Dark Matter (DM ...

Search for direct pair production of supersymmetric partners to the $${\uptau }_{}^{}$$ τ lepton in proton–proton collisions at $$\sqrt{s}=13\,\text {TeV} $$ s=13TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
A search is presented for $${\uptau }_{}^{}$$ τ slepton pairs produced in proton–proton collisions at a center-of-mass energy of 13$$\,\text {TeV}$$ TeV . The search is carried out in events containing two $${\uptau }_{}^{}$$ τ leptons in the final state,

NMSSM neutralino dark matter [PDF]

open access: yesAIP Conference Proceedings, 2007
We study the viability of the lightest neutralino as a dark matter candidate in the Next-to-Minimal Supersymmetric Standard Model. Taking into account accelerator constraints as well as bounds on low-energy observables, and imposing consistency with present bounds on the neutralino relic density, we address the prospects for the direct detection of ...

Revisiting a Realistic Intersecting D6-Brane with Modified Soft SUSY Terms

open access: yesUniverse
Because there are a few typos in the supersymmetry-breaking sfermion masses and trilinear soft term, regarding the current Large Hadron Collider (LHC) and dark matter searches, we revisit a three-family Pati–Salam model based on intersecting D6-branes in

The R-parity violating decays of charginos and neutralinos in the B-L MSSM

open access: yesJournal of High Energy Physics, 2019
The B − L MSSM is the MSSM with three right-handed neutrino chiral multiplets and gauged B − L symmetry. The B − L symmetry is broken by the third family right-handed sneutrino acquiring a VEV, thus spontaneously breaking R-parity. Within a natural range

Searching for the Higgsino-Bino sector at the LHC

open access: yesJournal of High Energy Physics, 2020
We study the search for electroweakinos at the 13 TeV LHC in the case of heavy scalar superpartners. We consider both the direct production mode and the one associated with the decay of heavy Higgs bosons, and concentrate on the case of light Higgsinos ...

Search for direct top squark pair production in events with one lepton, jets, and missing transverse momentum at 13 TeV with the CMS experiment

open access: yesJournal of High Energy Physics, 2020
A search for direct top squark pair production is presented. The search is based on proton-proton collision data at a center-of-mass energy of 13 TeV recorded by the CMS experiment at the LHC during 2016, 2017, and 2018, corresponding to an integrated ...

Measurement of radiative neutralino production

open access: yes, 2012
We perform the first experimental study with full detector simulation for the radiative production of neutralinos at the linear collider, at sqrt{s} = 500 GeV and realistic beam polarizations. We consider all relevant backgrounds, like the Standard Model background from radiative neutrino production.

Combination and reinterpretation of LHC SUSY searches

open access: yesJournal of High Energy Physics
To maximise the information obtained from various independent new physics searches conducted at the LHC, it is imperative to consider the combination of multiple analyses.
