An alternative formulation of infra-red counterterms
I. Jack
We present an alternative procedure for defining infra-red counterterms within dimensional regularisation for use in the procedure. The counterterms are given by simple close…

No- schemes for multi-coupling theories
Ian Jack
We show that even -functions may be removed from the -functions of general multi-coupling theories up to high loop order by means of coupling redefinitions. For theories whos…
