Three ways to weigh a quark

Recent years have seen order of magnitude improvement in knowledge of quark mass parameters — these advances have been due largely to theoretical and computational advances in lattice QCD simulations. Present day calculations are able to obtain percent-level uncertainties; reducing these even further will be important for precision Higgs studies and BSM searches. I will... More »

Cosmological Parameter Constraints from the Dark Energy Survey Supernova Program Three Year Spectroscopic Sample

Dillon Brout, U Penn
Type Ia Supernovae remain a crucial probe in the race to measure properties of Dark Energy as they trace a wide range of the expansion history of the universe and provide complementary constraints on cosmological parameters to those of the cosmic microwave background, weak lensing, baryon acoustic oscillations, and galaxy clustering. The Dark Energy Survey... More »

(Rel)-axions and SM hierarchies

I will discuss two scenarios which connects the strong CP problem to other hierarchies of the Standard Models. In the “axiflavon”, solving the flavor problem with a global abelian flavor symmetry naturally leads to an axion that solves the strong CP problem and constitutes a viable Dark Matter candidate. In the less tuned window for Dark Matter... More »
