# Reweighting for Topology at High Temperatures

#### Reweighting for Topology at High Temperatures

- Event time: 5:00pm
- Event date: 20th January 2021
- Speaker: Prof Guy Moore (Technical University of Darmstadt)
- Location: Online - see below

### Event details

Motivated by its importance for the cosmology of axions (a dark matter candidate), we examine how to compute the topological susceptibility of QCD

nonperturbatively on the lattice at temperatures well above the QCD transition temperature. In this regime topological structures are rare in the QCD

thermal ensemble, and reweighting methods are needed to sample them effectively. We introduce the subject and show how to carry out such

reweighted computations in lattice QCD.

### About Particle Physics Theory seminars

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
