Search potential for $\tilde{b}_{1} \rightarrow t W \tildeχ_{1}^{0}$ via $\tildeχ^{\pm}_{1}$ at the LHC and HL-LHC, with multi-lepton signatures Open
The search potential for sbottom pair production in an R-parity conserving scenario is explored in multi-lepton final states at LHC Run-3 and the HL-LHC. In this model, the sbottom decays via a chargino, $\tilde{b}_1 \to t \tildeχ_1^\pm$, …

Experimental search potential for sbottom via χ1± decays at the LHC Run-3 and HL-LHC, in final states with same-sign leptons and multiple jets Open
This paper explores the experimental search potential for sbottom pair production in an R-parity conserving scenario at the LHC Run-3 and HL-LHC. The sbottom decays with a 100% BR via a chargino, [Formula: see text], which subsequently dec…

Originally motivated for the generation of (Majorana) neutrino masses, the Type 2 Seesaw Model has also a rich extended Higgs sector with, if accessible at the LHC, a distinctive phenomenology of neutral, charged and doubly-charged states.…

ATLAS searches for higgsinos with <i>R</i>-parity violating couplings in events with leptons Open
This paper presents two searches for supersymmetry through the direct production of pairs of higgsinos decaying into final states with leptons and (b-) jets. The analyses are performed using 139[Formula: see text]fb[Formula: see text] of t…

Performance of charged-particle reconstruction within energetic jets in ATLAS for Run 3 data taking Open
For LHC Run 3 data taking the track reconstruction algorithm used for the ATLAS Inner Detector has been optimized with a particular focus on minimizing the number of erroneous and low-quality (fake) tracks processed by rejecting them as ea…

Search for supersymmetry in final states with two same-sign or three leptons and jets using 13 TeV ATLAS data Open
A search for strongly produced supersymmetric particles using signatures involving multiple energetic jets and either two isolated same-sign leptons (e or µ), or at least three isolated leptons, is presented. The analysis relies on the ide…

Inclusive searches for squarks and gluinos in final states with no leptons with the ATLAS detector Open
Despite the absence of experimental evidence, weak scale supersymmetry remains one of the best motivated and studied Standard Model extensions. This document summarises recent ATLAS results on inclusive searches for supersymmetric squarks …

Search for new physics in events with same sign leptons and missing energy with ATLAS at LHC Open
The Standard Model of particle physics describes the phenomena in the infinitesimal with great success. However, it suffers from several inadequacies~: it can not explain the neutrino masses, it has no candidate for the dark matter and it …
