Abstract: The elemental abundance patterns of stars encode a wealth of information about the history of the Milky Way galaxy and the astrophysical processesthat create atomic nuclei. I will describe some of what we have learned about the origin of …
ABSTRACT: Diverse astrophysical and cosmological observations indicate that most of the matter in the Universe is cold, dark and non-baryonic. Traditionally the most popular dark matter candidates have been new elementary particles, such as WIMPs and axions. However Primordial Black …
ABSTRACT: (This is a Hybrid/ZOOM Meeting) The Daya Bay Reactor Neutrino Experiment was built to measure the smallest neutrino mixing angle, θ₁₃, using the oscillation of electron antineutrinos produced by the Daya Bay nuclear power complex in southern China. Using the …
Abstract: The question of what the identity of dark matter is, presents one of the most fundamental mysteries in physics today. An answer to this question will shed light on a wealth of physics beyond the Standard Model, and will …

Abstract: The explicit breaking of the PQ symmetry by higher dimensional operators can spoil the dynamical relaxation of the strong CP angle to its minimum of zero. One solution to this PQ “quality problem” is to introduce heavy QCD axions. …

ABSTRACT: (This is a Hybrid/ZOOM Meeting) Gravitational waves offer a powerful probe of early Universe phenomena. A particularly well-motivated BSM target for gravitational wave experiments is a first order phase transition in a dark sector, where bubbles of true vacuum nucleate …

In this panel discussion postdocs and students will have the opportunity to ask senior division scientists about how the faculty hiring process typically works and labs and universities, and how to put together a winning faculty application. The panelists will …
Abstract: The Particle Physics Community Planning Exercise (a.k.a. “Snowmass”) is organized by the Division of Particles and Fields (DPF) of the American Physical Society. Snowmass is a scientific study. It provides an opportunity for the entire particle physics community to …

Abstract: Primordial Black Holes are a potential candidate for explaining some, or even all, of the experimentally inferred dark matter abundance. In this talk I will motivate the existence of Primordial Black Holes and discuss their potential role as a …
