Contribution

First exploratory study presenting spectroscopy and anomalous dimension estimates for SU(2) with one adjoint Dirac fermion, indicating near-conformal dynamics.

Findings

Theory appears conformal or near-conformal.

Anomalous dimension of the chiral condensate is around one.

Results have implications for walking technicolor scenarios.

Abstract

We present a first exploratory study of SU(2) gauge theory with one Dirac flavour in the adjoint representation. We provide initial results for the spectroscopy and the anomalous dimension for the chiral condensate. Our investigation indicates that the theory is conformal or near-conformal, with an anomalous dimension of order one. A discussion of the relevance of these findings in relation to walking technicolor scenarios is also presented.
