problem for h > g g QCD = 2 [QCD]

Asked by Hans Zippert

Hi there,

I am trying to compute the LO decay rate for the loop induced process h > g g via the syntax

generate h > g g QCD=2 [QCD]
output TEST
launch

I get the error message

str : A compilation Error occurs when trying to compile /home/MG5_aMC_v3_1_1/TEST/SubProcesses/PV0_0_1_h_gg.
 The compilation fails with the following output message:
     gfortran -w -fPIC -ffixed-line-length-132 -O3 -c polynomial.f -o polynomial.o -I /home/MG5_aMC_v3_1_1/HEPTools/include
     gfortran -w -fPIC -O -ffixed-line-length-132 -c check_sa.f -o check_sa.o -I /home/MG5_aMC_v3_1_1/HEPTools/include
     check_sa.f:415:38:

       415 | CALL RAMBO(NEXTERNAL-2,ENERGY,PMASS(3),PRAMBO,WGT)
           | 1
     Error: Actual argument contains too few elements for dummy argument ‘xm’ (1/2) at (1)
     make: *** [makefile:95: check_sa.o] Error 1

The following processes have worked perfectly normal:
h > b b~
h > b b~ QCD=2 [QCD]

Is this really an error, or am I simply doing something wrong?

Thanks in advance!

Hi,

This issue has been fixed in the following release.
So you can update your version and that should fix your issue.

Cheers,
