Aetiological factors were sought prospectively in 55 babies with extrahepatic biliary atresia, in 105 with neonatal hepatitis, and in 11 with intrahepatic biliary atresia, seen as a result of nearlyâ€¦ (More)

We investigate the one-loop renormalisability of a general N = 1 2 supersymmetric gauge theory coupled to chiral matter, and show the existence of an N =

We calculate the three loop anomalous dimension for a general N = 1 supersymmetric gauge theory. The result is used to probe the possible existence of renormalisation invariant relationships betweenâ€¦ (More)

We explore a more general class of soft supersymmetry-breaking masses and interactions than that usually considered, both in general and in the MSSM context, where our results for the one-loopâ€¦ (More)

We present an elegant exact formula for the gaugino Î²-function in a softly-broken supersymmetric gauge theory, of the form Î² M = O(Î² g /g), where Î² g is the gauge Î² function and O is a simpleâ€¦ (More)

We calculate the two-loop Î²-functions for soft supersymmetry-breaking interactions in a general supersymmetric gauge theory, emphasising the role of the evanescent couplings and masses that areâ€¦ (More)

We present the full three-loop Î²-functions for the MSSM generalised to include additional matter multiplets in 5, 10 representations of SU(5). We analyse the effect of three-loop running on theâ€¦ (More)

We investigate the connection between the NSVZ and the DRED forms of the gauge Î²-function in an N = 1 supersymmetric gauge theory. We construct a coupling constant redefinition that relates the twoâ€¦ (More)

We present an exact formula for the Î²-function for the soft-breaking scalar mass in an N = 1 supersymmetric gauge theory, in the form of an operator acting on the anomalous dimension. In particularâ€¦ (More)
