Abstract: The Cosmology Large Angular Scale Surveyor (CLASS) aims to characterize the primordial gravitational waves at the level of tensor-to-scalar ratio of 0.01, and make a cosmic-variance-limited measurement of the optical depth to reionization. CLASS is an array of four …
Abstract: The Higgs boson mass determines its couplings to every other known particle - and it is a free parameter of the Standard Model of Particle Physics. Understanding the Higgs' connections with the rest of the universe requires measuring its mass experimentally. This talk presents the …
Abstract: Despite of the discovery of a Higgs-like particle in 2012, there are still many unanswered questions. Studying events with the same-sign dilepton and multilepton (SSML) may help to gain insight into those questions. In this presentation, I will give …

Abstract: Long-standing anomalies in short-baseline neutrino oscillation experiments suggest the existence of a new particle: the sterile neutrino. Unlike other neutrinos, sterile neutrinos do not interact via the weak nuclear force. Global fits to experimental data find a significant preference …

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 …
