Renormalization and Non-perturbative Dynamics in Conformal Quantum Mechanics
Jacob Hafjall, Thomas A. Ryttov
We study conformal quantum mechanics by first considering the perturbative -matrix in various dimensions. The model has two couplings and we study perturbatively the degree of u…
Hadronic Spectrum in the Chiral Large Extension of Quantum Chromodynamics
Axel Halgaard Kristensen, Thomas A. Ryttov
We study Quantum Chromodynamics in the chiral large limit which contains a left-handed Weyl fermion in the fundamental representation, a left-handed Weyl fermion in the two i…
A Comparative Study of Criticality Conditions for Anomalous Dimensions using Exact Results in an Supersymmetric Gauge Theory
Thomas A. Ryttov, Robert Shrock
Two of the conditions that have been suggested to determine the lower boundary of the conformal window in asymptotically free gauge theories are the linear condition, $γ_{\barψψ,IR…
Anomalous Dimensions at an Infrared Fixed Point in an SU() Gauge Theory with Fermions in the Fundamental and Antisymmetric Tensor Representations
Thomas A. Ryttov, Robert Shrock
We present scheme-independent calculations of the anomalous dimensions and of fermion bilinear operators and at an infrared fixed…
Scheme and gauge dependence of QCD fixed points at five loops
J. A. Gracey, R. H. Mason, Thomas A. Ryttov +1
We analyse the fixed points of QCD at high loop order in a variety of renormalization schemes and gauges across the conformal window. We observe that in the minimal momentum subtra…
Effect of Scheme Transformations on a Beta Function with Vanishing One-Loop Term
Thomas A. Ryttov, Robert Shrock
It is commonly stated that because terms in the beta function of a theory at the level of loops and higher are scheme-dependent, it is possible to define scheme transf…
