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: Creating, manipulating and detecting coherent, entangled quantum states and isolating quantum systems from decoherence is at the heart of future quantum information science technologies. With the rise of novel instruments in quantum electronics, the coherent emission and control of …
ABSTRACT: The motions of galaxies on top of the Hubble expansion, peculiar velocities, are a probe of clustering and the growth of structure in the Universe. For distance indicators, peculiar velocities manifest themselves as residuals on the Hubble diagram. Ongoing …
Abstract: 40 years ago, Caves, Thorne, and their collaborators asked the question: what are the fundamental quantum limits on the measurement of a small position displacement? The answers to these conceptual questions led to the first direct detection of a …

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 …
