ABSTRACT: In this talk, I explore the impact of stellar kinematics on understanding the particle nature of Dark Matter in three separate locations: the solar neighborhood, the Galactic center, and dwarf galaxies. I first discuss the implications of the different stellar components on direct detection experiments. To do so, I show how I can use the velocity distribution of stars … Read More
ABSTRACT: Functional methods, in particular efficient reorganization of the one-loop effective action, have in recent years made a reappearance in simplifying the problem of computing matching and running effects in Lorentz-invariant EFTs such as the SMEFT. This has lead to the appearance of universal one-loop effective actions, where many such effects are now known in closed form for arbitrary field-content. … Read More
Julio Parra-Martinez from UCLA Renormalization in (SM)EFT from an on-shell perspective Abstract: The Standard Model Effective Field Theory (SMEFT) provides a bottom-up, systematic way to quantify and explore the effects of physics beyond the Standard Model. In this context, my talk will describe how modern on-shell methods can aid the calculation of anomalous dimensions in EFTs with higher-dimension operators. Instead … Read More
