The matrix element method is widely considered the ultimate LHC inference tool for small event numbers, but computationally expensive. We show how a combination of two conditional generative neural networks encodes the QCD radiation and detector effects without any simplifying assumptions, and allows us to efficiently compute likelihoods for individual events. We illustrate our approach for...
Neutrinoless double-beta decay (0$\nu\beta\beta$) is a key process to address some of the major outstanding issues in particle physics, such as the lepton number conservation and the Majorana nature of the neutrino. Several efforts have taken place in the last decades in order to reach higher and higher sensitivity on its half-life. The next-generation of experiments aims at covering the...
A multi-TeV muon collider is one of the best candidates under investigation for the future development of high energy particle physics. Since the discovery of the Higgs boson at the LHC in 2012, a great effort has been made in order to probe its properties. Nevertheless, almost all the Higgs boson couplings to second and third generation fermions and self couplings are still out of reach and,...
The SABRE (Sodium iodide with Active Background REjection) experiment aims to detect an annual rate modulation from dark matter interactions in ultra-high purity NaI(Tl) crystals in order to provide a model independent test of the signal observed by DAMA/LIBRA. It is made up of two separate detectors; SABRE South located at the Stawell Underground Physics Laboratory (SUPL), in regional...
The result presents the search for dark matter produced in association with Higgs boson decaying into a pair of τ leptons performed in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector at CERN LHC. The data used in the study has been collected during Run-2 of CMS running and corresponds to an integrated luminosity of 137 fb − 1 . The results are interpreted in...
