Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

Abstract The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to
accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from …

We show that the recent detection of a gravitational wave (GW) background reported by
various pulsar timing array (PTA) collaborations including NANOGrav-15 yr, PPTA …

New physics in the neutrino sector might be necessary to address anomalies between
different neutrino oscillation experiments. Intriguingly, it also offers a possible solution to the …

The nuclear matrix elements that govern the rate of neutrinoless double beta decay must be
accurately calculated if experiments are to reach their full potential. Theorists have been …

The Majorana nature of neutrinos is strongly motivated from the theoretical and
phenomenological point of view. A plethora of neutrino mass models, known collectively as …

Abstract We present new Big Bang Nucleosynthesis (BBN) limits on the cosmic expansion
rate or relativistic energy density, quantified via the number N ν of equivalent neutrino …

Neutrinos are copiously produced at particle colliders, but no collider neutrino has ever
been detected. Colliders produce both neutrinos and anti-neutrinos of all flavors at very high …

Abstract Neutrinos are the Standard Model (SM) particles which we understand the least,
often due to how weakly they interact with the other SM particles. Beyond this, very little is …
