Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

The preponderance of matter over antimatter in the early universe, the dynamics of the
supernovae that produced the heavy elements necessary for life, and whether protons …

We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

Abstract The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a
variety of physics topics. The high-intensity proton beams provide a large neutrino flux …

The European Particle Physics Strategy Update (EPPSU) process takes a bottom-up
approach, whereby the community is first invited to submit proposals (also called inputs) for …

We have conducted a new search for the diffuse supernova neutrino background (DSNB)
flux at Super-Kamiokande (SK), with a 22.5× 2970-kton· day exposure from its fourth …

At the dawn of a new decade, particle physics faces the challenge of explaining the mystery
of dark matter, the origin of matter over antimatter in the Universe, the apparent fine-tuning of …

A bstract We make a comparative study of the neutrinoless double beta decay constraints on
heavy sterile neutrinos versus other direct and indirect constraints from both lepton number …
