Informal Seminar: Ed Bennett (Swansea University): First results for SU(2) Yang-Mills with one adjoint Dirac Fermion

We will have a seminar by Ed Bennett (Swansea University), who will be visiting the KMI for a week from Sept. 9th. The seminar starts from 4:00 p.m. on Tuesday, Sept. 10th. We expect it to be rather informal so that we can freely have discussions during the talk. We welcome anyone who is interested in the topic.

Speaker: Ed Bennett (Swansea University)

Place: ES621

Time: 4:00 p.m., September 10th

Title: First results for SU(2) Yang-Mills with one adjoint Dirac Fermion

Abstract: We present the first exploratory results for the SU(2) gauge theory with one Dirac flavour in the adjoint representation. We provide initial results for the spectroscopy, static potential and the anomalous dimension for the fermionic condensate. We also look at topological observables (the topological susceptibility and the instanton size distribution) in comparison with the two-flavour theory (Minimal Walking Technicolor) and the pure gauge theory. Our results indicate that the theory is conformal or near-conformal with a fermionic anomalous dimension of order ~O(1). These findings are relevant for walking technicolor scenarios.
