Indications for infrared conformal behaviour of SU(2) gauge theory with $N_f=3/2$ flavours of adjoint fermions
May 29, 2019
We present the results of a numerical investigation of SU(2) gauge theory with $N_f=3/2$ flavours of fermions, corresponding to 3 Majorana fermions, which transform in the adjoint representation of the gauge group. At two values of the gauge coupling, the masses of bound states are considered as a function of the PCAC quark mass. The scaling of bound states masses indicates an infrared conformal behaviour of the theory. We obtain estimates for the fixed-point value of the mass anomalous dimension γ* from the scaling of masses and from the scaling of the mode number of the Wilson-Dirac operator.
