Aim of work

— Studying the possibilty of installing new RPC in the

high eta region 1.6 <η < 2.4 through studying the physics process: Bs µµ

Activity Done

• 1. Started to learn about Delphes ,install it ,how to

process it ,trying to understand the configuration files and doing exercise provided in Delphes.

• 2. Started with producing some plots for Z to

dielectron as a beginning the next slide represents an example for one of the plots that produced

3

Z to ee

4

Eta region

• No. of events

PT

• No. of events

Activity Done

After that I started to process hepmc file that contains Bs to mu mu events ,and according to the following plots(examples

• f the plots produced) we’ve small fraction of mu mu events

so we need to generate large sample.

5

Bs to mu mu

6

Eta region

• No. of events
• No. of events

PT

Activity Done

— Therefore,I needed to learn how to generate such

processes using Madgrph5,unfortunately Bs is not implemented in madgraph ,but can be added,so I started with producing Z to mu mu sample.

— Meanwhile time implemented for muons (just initial

step) by Michele Selvaggi (member of Delphes team thanks to him)

7

To Be done

— Trying to understand the plots produced after time

implemented and discussing them with Delphes experts.

— Study how to generate Bs to mu mu with large

sample using Madgraph or Pythia to start Triggering and reconstruction studies for high Eta region.
