complete 1-loop
corrections to the Bhabha cross-section in the Standard Model;
the 1-loop
corrections to the massive Bhabha cross-section in QED and in n space-time
dimensions, including also terms proportional to (n-4).
The latter are needed for a 2-loop calculation.
Results in electroweak model (EWSM).
Notation:
den(a,b)=1/(a-b); in such function argument a contains a
Mandelstam variable (`s'man) and b contains a
mass squared (MM`particle')
dct(a) corresponds to delta as counterterm parameter
T0(2), T3(4,i,j,k) are loop functions B_{0}, D_{i,j,k} as
examples. Arguments given with Looptools notation in accompanying funtion Targ()

activities around the 1-loop corrections, go to the homepages of
