Hi all,

I have commited new version of DPM generator.
Full elastic scattering, Coulomb, interference, hadronic parts are included in the new DPM.

You need to put the minimal angle of scattering -"tetmin"(>0) at DPM running, if you give value of parameter
"Elastic" = 1 (Inelastic with Elastic scatterings)
or = 2 (only Elastic scatterings).

The implementation of full elastic scattering in DPM is
important for Luminosity monitoring and, may be, for estimation of radiation doses in MVD.

Hi,

This change is also propagated to the PndDpmDirect class, i.e:

PndDpmDirect(Double_t Mom, Int_t Mode, Float_t tetmin=0)

The constructor of the PndDpmDirect has now an optional parameter tetmin. In case one choose elastic (Mode=1 or 2) and the theta is not set by user a warning will be printed out and the value is set to zero!

regards

Mohammad

Hi Aida,

thanks for uploading the new DPMGen version!

I have a question regarding the cross sections for the different processes (to my understanding inelastic, strong elastic, coulomb elastic) you implemented.

When I generate a given number of events with DPMGen, requesting elastic and inelastic events at a fixed parameter set, how many of these events will be inelastic, strong elastic, coulomb elastic?

Additionally, I have the same question concerning the previous DPMGen version without coulomb interaction: For a fixed number of events, how many of them will be elastic and how many inelastic?

Best regards,

Marius

Hi Marius,

please, send me your e-mail address,
and I can send you a version of programm codes
to receive information for cross-sections of
Coulomb, Interference and Hadron parts
of elastic scattering. There are some "print" operators
in fortran codes.

If I put corresponding "print"s
of your required values in fortran codes in current version DPM
and commit it,
it will be crushed, because option "lg2c" is removed
from "binmarke_Fortran.mk" file.

So, I can send you the needed files separately and explain how
to use them.

best regards, Aida

Hi Aida,

thanks a lot! You should have received an email from me via the forum system in the meantime. If it didn't work for some reason, please let me know.
