Abstract: Quantum fluctuations in inflation provide the seeds for the large scale distribution of matter today. According to the standard paradigm, these fluctuations induce density perturbations that are Gaussian distributed. In this limit, all the information is contained within the …

Abstract:  This seminar will present recent results of a search for long-lived heavy neutral leptons (HNLs) in proton-protoncollisions at the Large Hadron Collider (LHC). The Standard Model (SM) of particle physics is an extremely successful theory and its major predictions have …

Abstract: The existence of long-lived particles (LLPs) is a common feature in many theories beyond the Standard Model. For example, models with small couplings (i.e. R-parity-violating supersymmetry) and models with compressed mass spectra (i.e. co-annihilating dark matter) predict the presence …
