Hi all,
I have added and committed
new files PndUrqmdSmmGenerator.cxx(h) in pgenerators
package. The corresponding changes are made in files
pgenerators/PgenLinkDef.h and pgenerators/Makefile.am.
Due to these, now there is a possibility to work with
out root-files from UrqmdSmmGen as with root-files
from DpmGen. It is enough to replace "Dpm" to "UrqmdSmm".
For testing purposes, I calculated 10000 Events
of pbar+C reaction at momentum 3.1 GeV/c by UrqmdSmmGen.
Output root-file "pbarC_3_1_GeV.root" is disposed in
lxi00X cluster in /d/panda02/urqmd_smm/ .
If somebody has a special request for number of generated
events of pbarA-reactions at defined momentum and
nuclear target, please, send me the corresponding
request. I will calculate them with UrqmdSmm generator.
Best regards, Aida

Hi all,
You can use the next added calculations by UrQMD_SMM model.
pbar+Au at momentum 4.05 GeV/c, two out-root files with 5000
Events, "pbarAu_4_05_GeV_1.root", "pbarAu_4_05_2.root"
pbar+Cu at 3 GeV/c, 10000 Events, out-root file
"pbarCu_3.root"
pbar+C at 3 GeV/c, 10000 Events, out-root file
"pbarC_3.root"
pbar+Pb at 3 GeV/c, two out-root files with 5000 Events,
"pbarPb_3_GeV_1.root", "pbarPb_3_GeV_2.root".
These files are in lxi00X.gsi.de cluster in
/d/panda02/urqmd_smm
Good luck, Aida

Hi Aida,
i know that the standard panda reactions are produce
taking into account the vertex (0,0,0). but i wonder if it is possible to generate with the PndUrqmdSmm, reactions pbarp at 3.0 GeV in (0,0,-76 cm),
( otherwise i can not use it for my purpose ) or at least
to be able to swich the vertex in the running macro
something like PndUrqmdSmm("file.root",X,Y,Z)
if not i will be even happy having a file with the reaction
pbarp at 3.0 GeV in (0,0,-76 cm).
Thanks a lot
Alicia S.

Hi Alicia,
Really, in the out_root_file created by UrQMDSmm or Dpm generators,
the position of vertex is (0.,0.,0.).
But, I think when you use corresponding out_root_file, generated
by Event generator, in your macro for simulation of detector,
you can take the needed coordinate from root_Tree (as leaf of Tree) and
change it, according to the requirement of your task.
In PndJRGen there is possibility directly
to smear vertex in the macros for generation of events.
Vertex.SetXYZT(0,0,0,0); // zero by default
// smearing of the primary vertex (Gauss with the above mean, and this sigma)
//TVector3 VtxRes(.1,.1,.2); // what target smearing do you want???
TVector3 VtxRes(0,0,0);
This can be useful for you.
Good luck,
Aida
