LC extensions and examples for SGV


Geometry description.

To run SGV for the LC, use the the TESLA example geometry that comes with SGV, with the name sgv_geo2_ex.tit on the $SGV_PAM area. An alternative file, put together by Volker Adler, can be found here, and a more detailed description of the VD, from Pawel Luzniak, can be found here.

Example of an analysis job

The pam-file lc.car. contains a small example of an analysis job. I can be used as a template for further ellaboration. Note that it is ready to handle multiple detector-layouts in the same run.

The cradle lc_sgv23.cra. will correctly assemble the program, if You use cresgvexe.ksh (or .com), see the SGV User's Guide. It is identical to the cradle created by cresgvexe.ksh ( with argumets 'crecra lc_sgv23'). (For VMS, use cradle lc_sgv23_vms.cra. ) Note that the same cradle can be used for any of the intefaced event-generartors, by switching +USE cards. (For interfacing with SUSYGEN, see the User's Guide).

The script sgvass_sgv23.ksh or the com-file sgvass_sgv23.com can be used to make the correct assignments. They differ from the ones on $SGV_PAM in that they also take the input gemetry and steering file names as aruments, and that the output hbook-file is on the directory specified as argument 2 and with the name specified by argument 1.

The kumac-file lc_sgv23.kumac. can be used to create the histogram and ntuple file. It includes a non-trivial juggling with sub-directories, such that each detector-layout will have identical histograms and ntuples, but on different subdirectories. Note that, contrarry to the example on $SGV_PAM, it takes one argument, the name of the hbook-file.

Finally, as an example, the title-file lc_pythia6_tt_sgv23.tit contains the steering-cards for SGV and PYTHIA6 (pythia 6.136) for ttbar events at 500 GeV. This only differs form the sample on $SGV_PAM in the selected process and the beam-energy.
