On the Question of a Possible Infrared Zero in the Beta Function of the Finite- Gross-Neveu Model
Gongjun Choi, Thomas Ryttov, Robert Shrock
We investigate whether the beta function of the finite- Gross-Neveu model, as calculated up to the four-loop level, exhibits evidence for an infrared zero. As part of our analys…
Scheme-Independent Calculation of for an SU(3) Gauge Theory
Thomas A. Ryttov, Robert Shrock
We present a scheme-independent calculation of the infrared value of the anomalous dimension of the fermion bilinear, in an SU(3) gauge theory as a function of the…
Infrared Zero of and Value of for an SU(3) Gauge Theory at the Five-Loop Level
Thomas A. Ryttov, Robert Shrock
We calculate the value of the coupling at the infrared zero of the beta function of an asymptotically free SU(3) gauge theory at the five-loop level as a function of the number of…
Conformal Phase Diagram of Complete Asymptotically Free Theories
Claudio Pica, Thomas A. Ryttov, Francesco Sannino
We investigate the ultraviolet and infrared fixed point structure of gauge-Yukawa theories featuring a single gauge coupling, Yukawa coupling and scalar self coupling. Our investig…
Consistent Perturbative Fixed Point Calculations in QCD and SQCD
Thomas A. Ryttov
We suggest how to consistently calculate the anomalous dimension of the operator in finite order perturbation theory at an infrared fixed point for asymptotically fr…
