The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

We lay out a comprehensive physics case for a future high-energy muon collider, exploring
a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the …

This paper presents results of searches for the electroweak production of supersymmetric
particles in models with compressed mass spectra. The searches use 139 fb-1 of s= 13 TeV …

A search for chargino–neutralino pair production in three-lepton final states with missing
transverse momentum is presented. The study is based on a dataset of s= 13 TeV pp …

A search for long-lived charginos produced either directly or in the cascade decay of heavy
prompt gluino states is presented. The search is based on proton–proton collision data …

A bstract Results of a search for new phenomena in final states with an energetic jet and
large missing transverse momentum are reported. The search uses proton-proton collision …

In this" provocative" book (New York Times), a contrarian physicist argues that her field's
modern obsession with beauty has given us wonderful math but bad science. Whether …

A bstract Results are reported from a search for supersymmetric particles in the final state
with multiple jets and large missing transverse momentum. The search uses a sample of …

A bstract We analyse the possibility of describing quark masses, mixing and CP violation
in\({S} _4^{\prime}\) modular flavour models without flavons. We focus on the case where the …

Half a century after its formulation, the Standard Model (SM) is by now the established theory
of Electro-Weak (EW) and Strong interactions, the discovery of the Higgs boson being the …
