Rare decays of heavy-quark hadrons provide a powerful way to probe indirectly for presence of phenomena beyond the Standard Model of particle physics.
At the LHCb experiment several ${b\to s\ell\ell}$ transitions, such as the rare decays $B\to K\ell\ell$ or ${B\to K^{*}\ell\ell}$, have been studied. They show tensions towards the Standard Model predictions in several observables, such as...
The Standard Model (SM) of particle physics is our best description of the fundamental forces and particles in the universe, though there are many observed effects that it does not explain. To explain such phenomena, we require new physics. The top quark, as the heaviest known fundamental particle, offers a window into potential new physics. This talk focuses on measurements of rare top quark...
Measurements of the multiboson production cross sections at the LHC constitute stringent tests of the electroweak sector of the standard model and provide a model-independent means to search for new physics at the TeV scale. These measurements reached a high level of precision with LHC run 1 and run 2 data taking periods. In this presentation, the latest results of diboson (WW, WZ, ZZ, W/Zγ),...
The XENON collaboration is dedicated to understand the nature of dark matter. The XENONnT experiment, located at Laboratori Nazionali del Gran Sasso (LNGS) in italy, is aiming for a direct detection of weakly interacting massive particles (WIMPs) with a ton-scale dual-phase xenon time projection chamber. XENONnT has completed its first science run and is now taking data for the second science...
Experimental research in astroparticle physics is performed using large scale setups and involves accumulation of big data amounts in long-term time scales. A remarkable example of such experiment is KASCADE (KArlsruhe Shower Core and Array DEtector), which took place from 1996 until 2013 at the location which is now KIT university Campus Nord. Fulfillment of the inverstigation goals at every...
