ABSTRACT: Neutrino oscillation experiments such as NOvA and T2K search for the disappearance and appearance of muon and electron flavor neutrinos in a predominately muon-type beam. These experiments are currently measuring the oscillation parameters to greater precision but will not …
ABSTRACT: Theories beyond the Standard Model of particle physics often predict new, light, feebly interacting particles whose discovery requires novel search strategies. A light particle, the QCD axion, elegantly solves the outstanding strong-CP problem of the Standard Model; cousins of …

ABSTRACT: Neutrino oscillation is a well-established phenomenon. Over the past two decades, nearly all of the parameters governing these oscillations have been measured experimentally, using neutrinos from the atmosphere, the sun, nuclear reactors, and particle accelerators. The remaining unknowns have …
Abstract: The Mu2e experiment will search for the charged lepton flavor violating (CLFV) neutrino-less conversion of a negative muon into an electron in the field of a nucleus, reaching a 90% C.L. limit of 8x10^-17 on the conversion rate. This …
Abstract: The ability of current and next generation accelerator based neutrino oscillation measurements to reach their desired sensitivity requires a high-level of understanding of the neutrino-nucleus interactions. These include precise estimation of the relevant cross sections and the reconstruction of …

ABSTRACT: The Gaia mission has provided distance and velocity measurements of over a billion stars in the Milky Way, making it the largest stellar catalog at hand. Simultaneously, recent developments in cosmological simulations have made it possible to track stars …

Abstract: The three Nambu-Goldstone bosons in the longitudinal modes of the W and Z together with the Higgs boson span a 4-dimensional manifold. The geometry of this manifold, invariant under field re-parametrization, encodes the scalar dynamics which are vastly unexplored …

Abstract: The American Physical Society’s Division of Particles and Fields is gearing up for its next community planning process (for historical reasons, called Snowmass). This process will occur over the next year and culminate in a 10 year plan (with …
Abstract: Measurements of the universe's present-day expansion rate, or the Hubble constant (H0), that use a Cepheid variable star calibration of Type Ia supernovae (SNe Ia) are in >4σ disagreement with values predicted by the standard, Lambda cold dark matter …
