The talk will cover the latest searches for DM at LHC, with particular emphasis on the benchmark models used in the ongoing searches,
including Higgs portal models, simplified models with s and t-channel mediators and models with extended Higgs and gauge sectors.
Prospects for DM searches in Run-3 will also be discussed.
The proposed LUXE experiment (LASER Und XFEL Experiment) at DESY, Hamburg, using the electron beam from the European XFEL, aims to probe QED in the non-perturbative regime created in collisions between high-intensity laser pulses and high-energy electron or photon beams. This setup also provides a unique opportunity to probe physics beyond the standard model. In this talk we show that by...
Evidence for Dark Matter particles arising from direct searches has proven to be extremely elusive. An alternative approach to probing the dark sector is to search for new force carriers which can interact with Standard Model particles. A theoretically well-motivated model has proposed the presence of a new U(1) gauge boson, the heavy photon A', which might be a mediator between light thermal...
HUNTER (Heavy Unseen Neutrinos from Total Energy-momentum Reconstruction) is a future experiment that will search for additional “sterile” neutrinos beyond the Standard Model (BSM) using an instrument for radioactive atom trapping and high-resolution decay product spectrometry. HUNTER will be a concise experimental test for the existence of a sterile neutrino with masses between a 10-100 keV...
Particle physics today faces the challenge of explaining the mystery of dark matter, the
origin of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent fine-tuning of the electro-weak scale, and many other aspects of fundamental physics. Perhaps the most striking frontier to emerge in the search for answers involves new physics at mass scales comparable to...
Searches in CMS for dark matter in final states with invisible particles recoiling against visible states are presented. Various topologies and kinematic variables are explored, including jet substructure as a means of tagging heavy bosons. In this talk, we focus on the recent results obtained using the full Run-II dataset collected at the LHC.
New physics may have gone unseen so far at the LHC due to it being hidden in a dark sector. This may result in a rich phenomenology which we can access through portal interactions. In this talk, we present recent results from dark-sector searches in CMS using the full Run-II data-set of the LHC. The analyses are based on proton-proton collision data corresponding to an integrated luminosity of...
Collider searches for dark matter (DM) so far have mostly focussed on scenarios where DM particles are produced in association with heavy standard model (SM) particles or jets. However, no deviations from SM predictions have been observed. Several recent phenomenology papers have proposed models that explore the possibility of accessing the strongly coupled dark sector, giving rise to unusual...
The presence of a non-baryonic Dark Matter (DM) component in the Universe is inferred from the observation of its gravitational interaction. If Dark Matter interacts weakly with the Standard Model (SM) it could be produced at the LHC. The ATLAS Collaboration has developed a broad search program for DM candidates in final states with large missing transverse momentum produced in association...
