#### The spectrum of QCD with one flavour – A Window for Supersymmetric Dynamics

- Event time: 2:00pm until 3:00pm
- Event date: 1st March 2023
- Speaker: Justus Tobias Tsang (CERN)
- Location: Higgs Centre Seminar Room, Room 4305, James Clerk Maxwell Building (JCMB) (James Clerk Maxwell Building (JCMB)) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

We study QCD with a single quark flavour on the lattice, probing

predictions from effective field theories that are equivalent

to minimal super-symmetric Yang-Mills theory in the large NC limit.

Since lattice simulations with an odd number of Wilson fermions can

give rise to regions of configuration space with a negative fermionic

weight, they can be afflicted by a sign problem. I will present a

detailed analysis of this and report on observed cases of a negative

fermion determinant in our ensembles. Finally, I will outline our plans

to extend this calculation to larger numbers of colours.

### 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..
