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 …

This review demonstrates the unique role of the neutrino by discussing in detail the physics
of and with neutrinos. We deal with neutrino sources, neutrino oscillations, absolute masses …

Scattering of high energy particles from nucleons probes their structure, as was done in the
experiments that established the non-zero size of the proton using electron beams. The use …

ProtoDUNE-SP ran at CERN in the NP04 beamline from September to November of 2018.
Before that run, several data challenges at high rate validated the data transfer mechanisms …

The Deep Underground Neutrino Experiment (DUNE) is an international, world-class
experiment aimed at exploring fundamental questions about the universe that are at the …

Belle II has reported the first evidence for B+→ K+ ν ν¯ with a branching ratio 2.7 σ higher
than the standard model expectation. We explain this and the MiniBooNE and muon …

We consider a simple extension of the Standard Model (SM) by a complex scalar doublet
and a singlet along with three sterile neutrinos. The sterile neutrinos mix with the SM …

This report summarizes the present status of neutrino non-standard interactions (NSI). After
a brief overview, several aspects of NSIs are discussed, including connection to neutrino …

Heavy neutral leptons (N) below the kaon mass are severely constrained by cosmology and
lab-based searches for their decays in flight. If N interacts via an additional force, N→ ν e+ e …

We show that one of the simplest extensions of the Standard Model, the addition of a second
Higgs doublet, when combined with a dark sector singlet scalar, allows us to i) explain the …
