Dear MG experts, I'm trying to generate a loop induced process using the loop_sm_MSbar_yb_yc model (we partially discussed this topic with some of you in an e-mail thread). I would like to generate some gridpacks to use in the CMS workflow but for now I have tried a MadGraph standalone approach. I've tested this setup with MG5_aMC_v2_6_5 and MG5_aMC_v2_9_18, both times without success. The process I'm trying to generate is the following: define lj = g u u~ d d~ s s~ generate g g > h [noborn=QCD] add process lj lj > h lj [noborn=QCD] If I try to generate this using the default loop_sm model the process runs through, while as soon as I add the line: import model loop_sm_MSbar_yb_yc-yc4FS the generation doesn't run through, stopping with the following output: MG5_aMC>import model loop_sm_MSbar_yb_yc-yc4FS INFO: Restrict model loop_sm_MSbar_yb_yc with file models/loop_sm_MSbar_yb_yc/restrict_yc4FS.dat .
