Sherpa 2.0.b2+Delphes fails

[Wojciech.Kotlarski@fuw.edu.pl]

Dear Sherpa authors,

Sherpa fails to compile with Delphes 3.0.10 support with the attached error. It seems that the structure of directories in Delphes has changed. Needed header files are indeed present but in different directories.

cheers, Wojciech

Dear Wojciech,

thanks for the report. I have tried to compile the interface with the new Delphes version, but the class structure seems to have changed. Unfortunately Delphes does not provide easy means to detect this, and neither does it provide a standardized include path. However, it may not be necessary to have a dedicated Delphes interface for version >3, because Delphes seems to contain converters which take HepMC2 as an input. You can write HepMC2 output with Sherpa quite easily, see http://sherpa.hepforge.org/doc/SHERPA-MC-2.0.beta2.html#Event-output-formats

Best Stefan

Dear Stefan,

You are of course right. The standard HepMC output is accepted by Delphes without any problems. The only reason for this inquiry is that manual says that the Delphes ROOT output is half the size of gziped hepmc. But this is not really important.

best, Wojciech
