ABSTRACT: We are now approximately 3 months into the next Snowmass process and a plethora of ideas is starting to surface. Technical maturity of the proposed facilities ranges from shovel ready to those that are still largely conceptual. Developments in …

Abstract: The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) concluded observations of the cosmic distance scale and the growth of structure in February, 2019. The three dimensional clustering in all samples from the Sloan Digital Sky Survey (SDSS) was used to …
Abstract: The prime energy producer in the sun is the fusion of hydrogen to form helium. However, there is more than one way for this fusion to take place: for stars the size of the sun or smaller, the proton-proton …
Abstract: A search for new physics with XENON1T revealed an excess of electronic recoil events in the (1 – 7) keV region, favoring signal over background with significances of 3.5 sigma for solar axions/ALPs, 3.2 sigma for an enhanced neutrino …
Abstract: A remarkable feature of the Standard Model (SM) is that each lepton flavour (electron, muon, tau) is equally likely to interact with a W boson. This is known as Lepton Flavour Universality. In a recent ATLAS measurement, a novel technique …
ABSTRACT: It is now well established that the dominant part of non-relativistic matter in the Universe is some substance which appears to be oblivious to any force but gravity. The nature of this dark matter remains a nagging puzzle, and several …

Abstract: The standard model of cosmology is built upon on a series of propositions on how the early, intermediate, and late epochs of the Universe behave. In particular, it predicts that dark energy and dark matter currently pervades the cosmos. …
Abstract: This seminar presents the search for the rare Higgs boson decay to a pair of muons performed by the CMS experiment at the LHC, based on the full Run 2 dataset. Events are categorized based on the characteristics of …
ABSTRACT Clustering of matter on large scales provides an important source of information on key cosmological parameters. To extract this information we need to understand the relation between the tracers we observe and the underlying matter field. The clustering strength …
