Description
It is expected that SU(2) gauge theory with N_f fundamental fermions has an infrared fixed point when N_f is between ~6 and 11. We study the hadron spectrum and scale setting in SU(2) gauge field theory with N_f=2,4,6 using hypercubic stout smeared Wilson-clover (HEX) action. The case N_f=2 is QCD-like, whereas N_f=6 is close to the lower edge of the conformal window. In our study length scales are determined by using gradient flow approach.
