We present a search for a new neutral vector boson ($Z^\prime$) produced in association with dark states that do not interact via the Standard Model interactions. The search is performed using proton-proton collisions at $\sqrt{s}=13~$TeV corresponding to an integrated luminosity of $140~$fb$^{-1}$ recorded by the ATLAS detector at the Large Hadron Collider. The $Z^\prime$ boson is assumed to...
Supersymmetry is one of the best-motivated proposals for physics beyond the Standard Model. One of the primary motivations for the supersymmetry rests on the observation that the LSP (lightest supersymmetric particle) in R-parity conserving models is massive, naturally neutral and stable. This synergy of properties casts the LSP as an excellent candidate for the dark matter (DM). The stau...
In this paper, we propose two sets of different CP-sensitive observables inspired by the Higgs production in association with the top quark. We employ a Dark Matter simplified model that couples a scalar particle with three generation fermions with a mass equal to that of the top quark. The reconstruction of the kinematic variables is presented at NLO accuracy for events associated with this...
In the wake of the recent computation of bound state formation cross-section for minimal dark matter quintuplet that introduces a new signal for indirect detection, we go through 15-year Fermi-LAT data looking for this new line. We examine Fermi-LAT data from the galactic center to assess its capability to detect or rule out a potential line arising from bound-state formation. Our findings...
The NA62 experiment at CERN took data in 2016–2018 with the main goal of measuring the $K^+ \rightarrow \pi^+ \nu \bar\nu$ decay. In this talk we report on the search for visible decays of exotic mediators from data taken in "beam-dump" mode with the NA62 experiment. NA62 can be run as a "beam-dump" experiment by removing the kaon production target and moving the upstream collimators into a...
Gravitational waves could be used as a novel probe of dark matter. In compact binary mergers with extreme mass-ratios, the gravitational interaction between the secondary object and its dark matter environment can speed up the inspiral, leaving an imprint on the gravitational waveform. With the recently approved LISA space interferometer, many extreme mass ratio signals will become detectable....
Prompt emissions from TeV blazars pair produce on the extragalactic background light and the resulting electrons and positrons then undergo inverse Compton scattering, giving rise to secondary gamma-rays. The non-observation of such reprocessed emission implies a suppression of cascades from TeV blazars. In addition to the deflection of the electron-positron pairs off the line of sight by the...
