can not run any nlo qcd examples

[hesam.kaveh@gmail.com]

Hi,when I try to run LHC_ZJETS example I get the follwing error: what is wrong with my installation? Please HELP!

Sherpa: Single_Virtual_Correction::SelectLoopProcess throws not implemented:

Couldn't find virtual ME for this process.

Exception_Handler::GenerateStackTrace(..): Generating stack trace {

0x7f37a766b8d0 in 'ATOOLS::Terminate()' (Exception_Handler.C:135) 0x4028e6 in 'main' (Main.C:71)

}

[anonymous]

and I continually get:

Library_Loader::LoadLibrary(): Failed to load library 'libProc_P2_2_2_6_24_16_5_0.so'.

and I have tried : export LD_PRELOAD=<prefix>/lib/SHERPA-MC/libSherpaMain.so but no progress!

Hi Hesam,

although Sherpa has a small library of simple one-loop processes, it cannot provide these one-loop amplitudes for arbitrary processes. For this purpose it has to be linked to an external dedicated one-loop code like BlackHat, OpenLoops or GoSam. Of those BlackHat and GoSam are publically available already and OpenLoops will be available soon. Looking into the documentation for these examples, e.g. http://sherpa.hepforge.org/doc/SHERPA-MC-2.1.0.html#LHC_005fZJets, you will find the switch Loop_Generator, with which the one-loop provider can be set process by process.

Once Sherpa is linked against one of these one-loop codes and the resepctive switch is set, Sherpa is run the following way:

1) Sherpa -f Run.dat

The process libraries are generated, code is written to disk

2) ./makelibs

The code is compiled into shared libraries

3) Sherpa -f Run.dat

Cross section integration starts and, once integrated, event generation starts.

For more information either have a look into the manual, http://sherpa.hepforge.org/doc/SHERPA-MC-2.1.0.html#Getting-started (linked from the download page or to be found in the Manual subirectory of your Sherpa installation), or if this does not help, please ask again.

Hope this helps, Marek

Tnx a lot but now I cant compile blackhat with this error: mv -f .deps/cut_Darren.Tpo .deps/cut_Darren.Plo
