3 questions with regards to a new PR(#3629)

Dear experts,

we have 3 questions with regards to a new PR (#3629) for our analysis TTtoSStt and are very much hoping you can help us:

1. We are using a new pair production VLQ model for CMS, eVLQ_v8.1.tar.gz, found at https://feynrules.irmp.ucl.ac.be/wiki/NLOModels, designed by Luca Panizzi, and already used by ATLAS. What steps do you recommend we follow, or whom should we contact to ensure the new model can be approved and used for our MC simulations?
2. Here is the link to our repository for generating the samples given the gridpack: https://github.com/mroguljic/generateCMS/tree/TPrimePair/one_step. And here is the link to the fragment we are using: https://github.com/mroguljic/generateCMS/blob/TPrimePair/one_step/inputs/B2G-RunIISummer20UL16wmLHEGEN-02702-fragment.py. How do we go about getting this fragment approved for our analysis?
3. We followed the steps in https://twiki.cern.ch/twiki/bin/view/CMS/B2GRun2MCGridpackProductionForVLQ for VLQ Pair Production. However our analysis is a 2d mass bump search and requires a 2d mass grid instead of the 1d mass file masspoints.txt as provided in the recipe. What is the recipe for 2d mass points instead?

Thank you for your help!

1. you just have to contact gen convneners to upload the model in cms database
2. your group mc contacts will be able to help you with it
3. not sure what the question is, if your analysis has two BSM particles (X and Y) masses to scan (20 mass points for X and 30 mass points for Y), you just create 20x30=600 gridpacks that correspond to the masses
