Using detector simulation tool

Asked by SAUMYEN KUNDU on 2019-07-12

Hi,

I wanted to run the realistic detector simulation like in Tevatron after showering with Pythia8. Now I have Delphes installed inside MG5 with the command 'install Delphes'. Now I can see Delphes doesn't support Tevatron simulation. The cards are all related to LHC. Though I noticed a card for Tevatron simulation with pgs (i.e., the 'pgs_card_TEV.dat').
Now can you suggest some way out? I mean how can I use the pgs package or alternatively how can I run the simulation with Delphes itself.

Regards
Saumyen

Hi,

PGS is so old (and not maintained for so many years) that I'm really reluctant to tell you how to use it.
This code was a tool created by a theoretician (as far as I know) and therefore it is not consider by experimentalist as "realistic".
So my advise is to not use it anymore. This being said you can TRY (0 guarantee that it will work) to install it via the command
install pythia-pgs. Note that the version of PGS4 installed in that way will not be the latest one (this one is from 2006 while the latest is 2012).

Concerning Delphes, my only suggestion would be to contact the authors of that tools directly to ask them if they have such cards (or know where to find those).

Cheers,

Olivier

Thanks, Olivier.

Yeah, I saw that I can still install pythia-pgs in MG5. But I stopped myself knowing that it's not supported.

For the Delphes simulation of Tevatron, let me reach the authors.

But another query that I have is this. When I choose to simulate detector with Delphes, how do I know what card is being used, I mean CMS or ATLAS or LHCb etc. I tried looking for it but couldn't find. Might be, though, I missed something somewhere. I am asking this because I ran the simulation for my process with Tevatron-like kinematic variables and also got some distributions with MA5. But, you know that can't be Tevatron simulation.

Thanks again,
Saumyen

The default card for delphes is their default one which is lhc like (I.e. a mix between atLas and cms

Cheers
