ABSTRACT: The axion is a hypothetical elementary particle whose existence would explain the baffling absence of CP violation in the strong interactions. Axions also happen to be a compelling dark-matter candidate. Axions could comprise the overwhelming majority of mass in …

Abstract: The 38th International Conference on High Energy Physics has just concluded in Chicago, US. New results from various areas of high-energy particle physics, as well as neutrino physics, cosmology and theory were presented in front of about 1400 attendees. …

Abstract: I'll briefly review the arguments for and status of particle dark matter searches and then focus on the possibility of looking for a definitive galactic signature. There have been several hints for WIMP dark matter over the years, most …
Abstract: KamLAND is a one-kiloton liquid scintillator-based neutrino detector and is one of the recipients of the 2016 Breakthrough Prize in Fundamental Physics for its 2002 investigation of neutrino oscillations. KamLAND-Zen is the current phase of KamLAND, and it is …

ABSTRACT: Wojtak, Hansen and Hjorth and others have measured the long-predicted gravitational redshift of light escaping from galaxy clusters using Sloan Digital Sky Survey data. The effect is very small, corresponding to a velocity shift of only ~10 km/s in …

Abstract: Much of the exploration of the high-redshift Universe has focussed on first finding sites of ongoing star formation. This can then lead to pointed follow-up of how much cold (molecular) gas there is that feeds this star formation. ALMA …
ABSTRACT: Supernovae remain a central part of dark energy science, complementing the programs with BAO and weak lensing. The LBNL group is active with the nearby supernova search with the SN factory, a role in the intermediate-redshift DES supernova program, …
Abstract: The large-scale structure of our universe (the distribution of galaxies on very large-scales for instance) contains a wealth of information about the origin, evolution, and matter content of the universe. Extracting this information relies crucially on understanding how galaxies …
Abstract: I'll remind us all of the motivation for Supersymmetry searches at the LHC, and provide a general overview of the status of the search. Since, even after results making use of in excess of 10 fb-1 of 13 TeV …
