MadGraph5_aMC@NLO

Reweighting error for lepton collider (Info file not found for PDF set...)

Asked by Alfredo Glioti

Hello,

I'm trying to generate a simple process at LO
   mu+ mu- > Z h
with the SMEFTatNLO model trying to reweight on some of the new physics parameter, but I keep getting errors during the reweighting step.

It seems like it's trying to read some PDF files but then it gets stuck since in my process I'm not using any.

Please tell me if you need more informations,
Alfredo

Here is the debug log of one of the failed runs:

# 2) It is (in general) dangerous/wrong to change parameters by a large

#
# Example of (standard) code for the computation of two weights:
#
# launch ! tag to start the computation of the first weight
# set BLOCKNAME ID VALUE ! rule to modify the current param_card
# set BLOCKNAME ID VALUE ! rule to modify the current param_card
# launch ! start to compute a second weight
# /home/Cards/param_card_2.dat ! you can also enter a path to a valid card
#
# Note: The command to specify the parameter are AFTER the associated "launch"
#
# Possible options:
# You can enter one of the following lines to customize the reweighting
# procedure. These need to be given before the 'launch' command.
#
# change model NAME : use another model for the matrix-elements to reweight
# with. In this case you need to provide the path to a correct
# param_card for the new model; you cannot modify the original one
# with the 'set' command.
# change process DEF [--add]: change the process by which you reweight.
# The initial and final state particles of the new process should
# be exactly identical to the ones in the original process.
# change helicity False: perform the reweighting by helicity summed
# matrix-elements even if the events have been written with a
# single helicity state.
# change mode XXX: change the type of reweighting performed.
# allowed values: LO, NLO, LO+NLO
# - This command has no effect for reweighting an .lhe event file with LO accuracy.
# In that case LO mode is always used (whatever entry is set).
# - When the .lhe file reweighted is at NLO accuracy, then all modes are allowed.
# * "LO" is an approximate leading order method
# * "NLO" is the NLO accurate method
# * "LO+NLO" runs both
# - "NLO" and "LO+NLO" modes requires 'store_rwgt_info' equals True (run_card.dat)
# If the reweighting is done at generation level this parameter will
# automatically be set on True.
