Error in tW [QCD] in loop_sm-no_b_mass
Hello everyone,
I am trying to generate an tW events at QCD NLO. The syntax I am using is,
import model loop_sm-no_b_mass
define p = 21 2 4 1 3 -2 -4 -1 -3 5 -5 # pass to 5 flavors
define j = p
define p = p b b~
generate p p > t w- > mu+ vm b e- ve~ [QCD]

are taken from the param_card.
Do NOT set these widths to zero in the param_card.
