Searching for Dark Matter with the ATLAS Detector
Dark matter’s presence can be inferred from gravitational interactions and astrophysical observations, but its nature is still unknown. If dark...

Searching for pseudo Nambu-Goldstone boson dark matter production in association with top quarks
Pseudo Nambu-Goldstone bosons (pNGBs) are attractive dark matter (DM) candidates, since they couple to the Standard Model (SM) predominantly through...

Search for a scalar partner of the top quark in the all-hadronic \(t{\bar{t}}\) plus missing transverse momentum final state at \(\sqrt{s}=13\) TeV with the ATLAS detector
A search for direct pair production of scalar partners of the top quark (top squarks or scalar third-generation up-type leptoquarks) in the...

On the coverage of neutralino dark matter in coannihilations at the upgraded LHC
In the supersymmetric models, the coannihilation of the neutralino DM with a lighter supersymmetric particle provides a feasible way to accommodate...

Evading Z′ boson mass limits in U(1)′ supersymmetric models
Supersymmetric models augmented by U (1)′ gauge symmetries resolve some of the outstanding problems in MSSM, such as the μ problem. Unfortunately...

Search for electroweak production of charginos and sleptons decaying into final states with two leptons and missing transverse momentum in \(\sqrt{s}=13\) \(\text {TeV}\) pp collisions using the ATLAS detector
A search for the electroweak production of charginos and sleptons decaying into final states with two electrons or muons is presented. The analysis...

A universal framework for t-channel dark matter models
We present the
DMSimpt model implementation in FeynRules , which aims to offer a unique general framework allowing for all simulations relevant for...

Simulation-based inference in the search for CP violation in leptonic WH production
Sources of CP violation beyond the Standard Model (BSM) are required to explain the baryonic asymmetry of the Universe. In this work, we study BSM...

Minimal vectorlike model in supersymmetric unification
Compared to the minimal supersymmetric standard model, an extension by vectorlike fermions is able to explain the Higgs mass while retains the grand...

Topology Classification with Deep Learning to Improve Real-Time Event Selection at the LHC
We show how an event topology classification based on deep learning could be used to improve the purity of data samples selected in real time at the...
