Final sample is not complete after pythia and delphes in ep collision
Dear Experts,
I am trying to generate SM below process with MadGraph 2.7.3, pythia8 and Delphes inside the MadGraph:
define p = p b b~
generate e- p > vl j b b~
In the general SM model (import model sm), it crashes. I tried with both:
import model sm-full
In this case I have used False = use_syst and nb_core = 1 to solve some problems especially pythia parallelization issue
second case:
import model sm-no_b_mass
After all, one problem still remained:
Number of data after delphes in the final root file is less than I generated in madgraph. e.g. about 200 event out of 10000.
I would be appreciated for any help.
Thanks,
Reza

Hi,
How many event did you have after MG5aMC? and after Pythia?
Did you contact Delphes author?
I would make sense Delphes has detector acceptance, did you change those to march a DIS type of detector?
Cheers,
Olivier

Dear Olivier,
Thanks for your prompt answer.
I just checked again now.
In the last run, the number of events after MG5aMC level for sm-full is correct (10k), but after Pythia is incorrect (0 event).
for sm-no_b_mass the number of events after both MG5aMC (90 events out of 10k) and Pythia (68 event) are wrong, as you can see below.
I just turned on Delphes in MG5aMC shell, nothing more.

What cut/setup did you use for MG5aMC.
Can you give me your full pythia8_card since i do not know how to setup it for dIS type of production.

! Specify the HEPMC output of the Pythia8 shower. You can set it to:
! auto : MG5aMC will automatically place it the run_<i> directory
! /dev/null : to turn off the HEPMC output.
! <path> : to select where the HEPMC file must written. It will
! therefore not be placed in the run_<i> directory. The
! specified path, if not absolute, will be relative to
! the Event/run_<i> directory of the process output.
! fifo : to have MG5aMC setup the piping of the PY8 output to
! analysis tools such as MadAnalysis5.
! fifo@<fifo_path> :
! Same as 'fifo', but selecting a custom path to create the
! fifo pipe. (useful to select a mounted drive that supports

! The following parameter was forced to be commented out by MG5aMC.
! Merging:TMS = -1.0
! This must be set manually, according to Pythia8 directives.
! An example of possible value is 'pp>LEPTONS,
! Alternatively, from Pythia v8.223 onwards, the value 'guess' can be
! used to instruct Pythia to guess the hard process. The guess would mean
! that all particles apart from light partons will be considered as a part
! of the hard process. This guess is prone to errors if the desired hard
! process is complicated (i.e. contains light partons). The user should
! then be wary of suspicious error messages in the Pythia log file.

!
! It is possible to run this card manually with:
! LD_LIBRARY_
!
!
! Pythia8 cmd card automatically generated by MadGraph5_aMC@NLO
! For more information on the use of the MG5aMC / Pythia8 interface, visit
! https:/
!
! ==================
! General parameters
! ==================
!
Main:numberOfEvents = -1
!
! -------
! Specify the HEPMC output of the Pythia8 shower. You can set it to:
! auto : MG5aMC will automatically place it the run_<i> directory
! /dev/null : to turn off the HEPMC output.
! <path> : to select where the HEPMC file must written. It will
! therefore not be placed in the run_<i> directory. The
! specified path, if not absolute, will be relative to
! the Event/run_<i> directory of the process output.
! fifo : to have MG5aMC setup the piping of the PY8 output to
! analysis tools such as MadAnalysis5.
! fifo@<fifo_path> :
! Same as 'fifo', but selecting a custom path to create the
! fifo pipe. (useful to select a mounted drive that supports
! fifo). Note that the fifo file extension *must* be '.hepmc.fifo'.
! -------
!
HEPMCoutput:file = tag_1_pythia8_
!
! -------
! Parameters relevant only when performing MLM merging, which can be
! turned on by setting ickkw to '1' in the run_card and chosing a
! positive value for the parameter xqcut.
! For details, see section 'Jet Matching' on the left-hand menu of
! http://
! -------
! If equal to -1.0, MadGraph5_aMC@NLO will set it automatically based
! on the parameter 'xqcut' of the run_card.dat
! The following parameter was forced to be commented out by MG5aMC.
! JetMatching:qCut = -1.0
! Use default kt-MLM to match parton level jets to those produced by the
! shower. But the other Shower-kt scheme is available too with this option.
! The following parameter was forced to be commented out by MG5aMC.
! JetMatching:
! A value of -1 means that it is automatically guessed by MadGraph.
! It is however always safer to explicitly set it.
! The following parameter was forced to be commented out by MG5aMC.
! JetMatching:nJetMax = -1
!
! -------
! Parameters relevant only when performing CKKW-L merging, which can
! be turned on by setting the parameter 'ptlund' *or* 'ktdurham' to
! a positive value.
! For details, see section 'CKKW-L Merging' on the left-hand menu of
! http://
! -------
! Central merging scale values you want to be used.
! If equal to -1.0, then MadGraph5_aMC@NLO will set this automatically
! based on the parameter 'ktdurham' of the run_card.dat
! The following parameter was forced to be commented out by MG5aMC.
! Merging:TMS = -1.0
! This must be set manually, according to Pythia8 directives.
! An example of possible value is 'pp>LEPTONS,
! Alternatively, from Pythia v8.223 onwards, the value 'guess' can be
! used to instruct Pythia to guess the hard process. The guess would mean
! that all particles apart from light partons will be considered as a part
! of the hard process. This guess is prone to errors if the desired hard
! process is complicated (i.e. contains light partons). The user should
! then be wary of suspicious error messages in the Pythia log file.
! The following parameter was forced to be commented out by MG5aMC.
! Merging:Process = <set_by_user>
! A value of -1 means that it is automatically guessed by MadGraph.
! It is however always safer to explicitly set it.
! The following parameter was forced to be commented out by MG5aMC.
! Merging:nJetMax = -1
!
! For all merging schemes, decide whehter you want the merging scale
! variation computed for only the central weights or all other
! PDF and scale variation weights as well
SysCalc:
!
! =======
! User customized parameters
! =======
!
! By default, Pythia8 generates multi-parton interaction events. This is
! often irrelevant for phenomenology and very slow. You can turn this
! feature off by uncommenting the line below if so desired.
!partonlevel:mpi = off
!
! Additional technical parameters set by MG5_aMC.
!
! Tell Pythia8 that an LHEF input is used.
Beams:frameType=4
! Specify one must read inputs from the MadGraph banner.
JetMatching:
JetMatching:
! 1.0 corresponds to HEPMC weight given in [mb]. We choose here the [pb] normalization.
HEPMCoutput:
! Be more forgiving with momentum mismatches.

Hi,
The issue with the sm-no_b_mass is that you do not have any cut on the b quark.
Looks like the maxjetflavour parameter is still 4 in this case. and therefore the "b" quark have their own set of cuts different of the ptj cut (and equivalent for other variable. Consequently you have a singular regime, the cross-section is technically not finite and it is not possible to generate events.
I would see what I can do to change the default value of maxjetflavour for such type of process and such model.
Concerning pythia8, I do not see any flag to have assymetric handling of the beam. I have never tried to use pythia8 for dIS type of collision so I have never learn how to configure pythia8 for such type of collision. I would advise you to read the pythia8 manual to learn that.
Cheers,
Olivier

Dear Olivier,
Thanks a lot for your time and checking the banner files.
I am looking forward to hearing from you about the first issue and I will try to solve the pythia8 problem.
Many thanks,
Reza

Dear Olivier,
Before you would see what you can do to change the default value of maxjetflavour for such type of process and such model,
would you please let me I should change maxjetflavour to 5 because in sm-no_b_mass model, b quark is a light quark ?

Hi,
You have to put cut on the b quark.
One easy way is to set maxjetflavour to 5 such that all default cut for light jet are also applied on b quark.
The second option is to keep maxjetflavour to 4 and add one cut preventing soft singularities and another one preventing collinear singularities.
Cheers,
Olivier

Dear Olivier,
Thanks a lot for your help. Both options solved the issue at the MadGraph level.
I am searching about Pythia8 problem now.

Dear Olivier,
As the problem solved in MadGraph level, now I could not handle Pythia8 and I think you are more familiar with Pythia6, I tried also with Pythia6.
The problem still exists. I would be appreciated if you take a quick look in pythia_card and below part of tag_1_pythia.log file:
Thanks,
Reza

Hi,
I did not run pythia6 since ~10 years so I actually know more about pythia8 than pythia6.
Pythia6 should not be used anymore, it is not supported anymore by the pythia author. So valid reason to use pythia6 today are very limited (reproduction of legacy result or tracking of very old bug).
You should really need to read the pythia8 manual to learn how to setup flag for such type of process.
If something is not clear in their manual, you should then contact the autors of the tool.
Cheers,
Olivier
