LM0 sample production Exercise 2009

I produce a private LM0 montecarlo sample using the Tier 2 from bari. This is a Summary page.

LM0 production

The configuration file can be found here LM0 config file to send a production you can use crab, and example of the configuration file I used is here Used Crab config file

The production has several steps, you should be sure that your works correctly before submit it to the grid.

  • Take the configuration file from this page
  • Edit the parameters you need to change
  • Be sure that it works for you in your local area
  • Edit the crab file so that both the CMSSW file and the crab file talk to each other
  • submit to grid
  • Wait a while check

The production I did has 200 pb^{-1} , and it is available from bari at the directory :


I used CMSSW_3_1_4 for the production

LM0 Reconstruction

Once you have completed the production, reconstruction is needed in order to have the RECO and the PF objects. The config file used for the reconstruction is this one

Reconstructed samples in bari are located at :


for the reconstruction CMSSW_3_1_4 was used

PAT production

The Pat tuples used where produced using the SUSY Pat Layer 1 Data V6 instructions. The CMSSW that was used was 3_1_4.

patuples are stored at :


PF2PAT production

For the production of the Particle Flow Patuples we used the recipe of PF2PAT, in this case we used CMSSW_3_3_2 because the jets were better implemented.

samples are located at :


the template for pf2pat production is here.
