No shower/hadronization option even after installing mg5amc_py8_interface

Asked by Isaac Wang on 2024-03-19

I'm using MG5 v3.5.3. I have manually installed pythia8 somewhere else and input the path in the configuration file. Then successfully installed the mg5amc_py8_interface.

Then I tried to generate some random process, e.g. p p > t t~. Then output, then launch. There is no shower/hadronization option.

Some output during the launching process:

INFO: load configuration from /Users/quarkquartet/Work/DM-enc/tt-coupling/bkg_tt/Cards/me5_configuration.txt
INFO: load configuration from /Users/quarkquartet/Work/MG5_aMC_v3_5_3/input/mg5_configuration.txt
INFO: load configuration from /Users/quarkquartet/Work/DM-enc/tt-coupling/bkg_tt/Cards/me5_configuration.txt
generate_events run_01
The following switches determine which programs are run:
/=================== Description ===================|============= values ==============|======== other options ========\
| 1. Choose the shower/hadronization program | shower = Not Avail. | Please install module |
| 2. Choose the detector simulation program | detector = Not Avail. | Please install module |
| 3. Choose an analysis package (plot/convert) | analysis = Not Avail. | Please install module |
| 4. Decay onshell particles | madspin = OFF | ON|onshell|full |
| 5. Add weights to events for new hypp. | reweight = OFF | ON |
\=======================================================================================================================/

I notice that the configuration file in the output directory is 'me5_configuration', is this a typo?

The configuration file in the output directory, however, is indeed 'me5_configuration.txt'. I can find it. But the pythia8 path and mg5amc_py8_interface path are both not properly configured. However those are properly configured in the MG5path/input/mg5_configuration.txt file.

Is there a bug in this output?

Update: I tried to manually write the correct mg5am_py8_interface and pythia8 path into the configuration file in the event/cards path. Does not work.

I noticed that when I start MG5, it reports that lhapdf and fastjet is loaded from the configuration file, but did not mention pythia8. However, the pythia8 configuration code is indeed there. The output for login mg5 is the following:

set lhapdf to /Users/quarkquartet/Work/local/lhapdf6-nopy/bin/lhapdf-config

Hi,

pythia8_path = /Users/quarkquartet/Work/DM-enc/tt-coupling/bkg_tt/None #

is likely an invalid path ...

Hi,

I do not know why I copied this line. But I reopened this file and the corresponding lines are

#! If using a relative path, that starts from the mg5 directory
pythia8_path = /Users/quarkquartet/Work/local/pythia8/bin/pythia8-config #

Then I re-run MG5, same result.

I got the origin of the problem. It's because the pythia8_path should refer to the pythia8 installation directory, instead of the `pythia8-config` file location.
