UV and IR Effects in Axion Quality Control
C. P. Burgess, Gongjun Choi, F. Quevedo
Motivated by recent discussions and the absence of exact global symmetries in UV completions of gravity we re-examine the axion quality problem (and naturalness issues more general…
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…
An Integral Formalism for the Construction of Scheme Transformations in Quantum Field Theory
Gongjun Choi, Robert Shrock
We present an integral formalism for constructing scheme transformations in a quantum field theory. We apply this to generate several new useful scheme transformations. A comparati…
Study of the Renormalization-Group Evolution of Supersymmetric Gauge Theories Using Padé Approximants
Gongjun Choi, Robert Shrock
We study asymptotically free SU() gauge theories with supersymmetry, including the purely gluonic theory and theories with copies of a pair of massless chir…
New Scheme Transformations and Application to Study Scheme Dependence of an Infrared Zero of the Beta Function in Gauge Theories
Gongjun Choi, Robert Shrock
We present two new one-parameter families of scheme transformations and apply these to study the scheme dependence of the infrared zero in the beta function of an asymptotically fr…
