10. Exploring the ultraviolet from neutrino oscillations and Neff in the EFT framework

Yong Du (ITP)

15/04/2021, 23:00

Since the discovery of the Higgs particle in 2012 at the LHC, the null observation from various experiments has gradually changed our strategy in searching for new physics from a model-dependent pattern into the EFT approach. In this talk, I will discuss our most recent work in this direction. The first part of my talk will mainly focus on constraining the ultraviolet physics within SMEFT by...

abstracts

We compute the leading-logarithm correction to the neutrino mass matrix in the Standard Model effective field theory to dimension seven. In the limit of negligible Yukawa couplings, the neutrino mass matrix receives contributions from the Weinberg operator as well as from ten dimension-six and four dimension-seven independent interactions. We discuss the conditions under which the derived...

14. Running in the ALPs

Mr Guilherme Guedes (University of Granada)

15/04/2021, 23:48

In this talk I will present the complete anomalous dimension matrix at 1 loop of the Standard Model effective field theory extended with an axion-like particle (ALP) up to dimension 5. The ALP couplings are probed by different experiments across a huge range of energy scales and as such, a consistent analysis of the corresponding constraints requires the use of the renormalization group...

2. Effective Field Theory of Dark Matter Direct Detection With Collective Excitations

Zhengkang Zhang (C)

16/04/2021, 00:12

I will present a framework for computing dark matter direct detection rates via phonon and magnon excitations in crystal targets for general dark matter models. It consists of parameterizing dark matter interactions by a nonrelativistic EFT, and computing material responses to the EFT operators. Our work extends previous calculations that focused on simple models such as standard...
