Transversal theory approach towards new physics The aim of WP1 is to explore novel ideas that address naturalness by studying their phenomenological implications in the context of the studies performed in the WP2, WP3, WP4, WP5. We plan to scrutinize existing theoretical proposals such as neutral naturalness, Mirror worlds, Clockwork, Relaxion, etc., as well as… Continue reading WP1

Higgs coupling determination and interpretation in the SMEFT   WP2 aims at bringing our current understanding of the H interactions to a new level by following a two-prong TH/EXP driven approach. On the one hand we will make cutting edge (differential) measurements of selected processes involving a Higgs (or HH) in the final state using… Continue reading WP2

New scalar resonances In this work package we aim to search for these extra (pseudo)scalars in a few key channels, H′ → VV, ZA, H′ → HH. A close collaboration between theory and experiment is foreseen for determining and simulating the expected signals and backgrounds, takinginto account interference and higher order effects; interpreting the results… Continue reading WP3

Hidden Sectors through the Higgs and kinematic portals A real singlet scalar DM particle coupled to the SM through the Higgs portal is the most minimal model of a hidden sector. The stability of the DM requires an ad hoc discrete symmetry. The absolute stability of DM might be guaranteed by a gauge symmetry, which… Continue reading WP4

Neutrino puzzle via the LH portal Since the SM predicts massless neutrinos, neutrino masses are, as of today, the only totally convincing laboratory evidence for the existence of physics beyond the SM. Unraveling the origin and mass generation mechanism for the neutrinos calls for a broad and rich experimental program, to which Belgium has remarkable… Continue reading WP5

Transversal developments on prompt and displaced objects The searches proposed in WP4 and WP5 share the presence of new particles decaying in the CMS detector with macroscopic displacement from the collision vertex into b-quarks, tau leptons, as well as electrons and muons. To efficiently identify these objects, dedicated experimental tools for reconstruction and identification must… Continue reading WP6
