$I ¨ ^{6}$ at $6$ (and some $8$ ) loops in $3 d$

Ian Jack, Hugh Osborn

We recalculate the contributions of individual six loop graphs to the $I^^{2}$ -function for a three dimensional scalar theory with an arbitrary sextic scalar potential. Previously this…

Asymptotic PadÃ© Predictions up to Six Loops in QCD and Eight Loops in $I^» I ¨ ^{4}$

J. A. Gracey, I. Jack, D. R. T. Jones

We assess the accuracy of our previous Asymptotic PadÃ© predictions of the five-loop QCD $I^^{2}$ -function and quark mass anomalous dimension in the light of subsequent exact results.…

Explorations in Scalar Fermion Theories: $I^^{2}$ -functions, Supersymmetry and Fixed Points

Ian Jack, Hugh Osborn, Tom Steudtner

Results for $I^^{2}$ -functions and anomalous dimensions in general scalar fermion theories are presented to three loops. Various constraints on the individual coefficients for each dia…

Anomalous dimensions for $I ¨ ^{n}$ in scale invariant $d = 3$ theory

I. Jack, D. R. T. Jones

Recently it was shown that the scaling dimension of the operator $I ¨ ^{n}$ in scale-invariant $d = 3$ theory may be computed semiclassically, and this was verified to leading order (two…
