In a certain (non-commutative) version of large-N SU(N) Yang-Mills theory there are special Wilson loops, called twistor Wilson loops for geometrical reasons, whose v.e.v. is independent on the param...

We present the calculation of the one-loop Yukawa coupling beta function to order Yg2 in a general a gauge, where Y and g are Yukawa and gauge couplings. We show explicitly how the gauge parameter a c...
