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: Particles produced in high energy collisions that are charged under one of the fundamental forces will radiate proportionally to their charge, such as photon radiation from electrons in quantum electrodynamics. At sufficiently high energies, this radiation pattern is enhanced …

ABSTRACT: Having discovered the Higgs boson without obvious new particles at the Large Hadron Collider, precision study of the Higgs boson at a Higgs factory is the obvious strategy at the energy frontier. I will review basic motivation and various …

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 …
