are the parameters in this file different from the default value in the model, we always suggest people use "customized card" which includes only the modified parameter

I have not modified any of the numbers in the section QUANTUM NUMBERS OF NEW STATE(S) (NON SM PDG CODE). Are you suggesting to remove them if they are standard?

Since my understanding is that leaving things as they were here shouldn't be a problem, I haven't touched this part.

Hi, my question is that there is parameter card in model MSSM_SLHA2, which parameter in your card is different from the defaults in the model. We always recommend to use 'customized card' to include the modified parameters different from the defaults

The only parameters that are different from the default are the neutralino masses. Shall I just leave those in the param_card and delete all the rest?

please use a customized card with this modified parameter only, and delete parameter card

I've made the requested changes and added a bash script to template the cards |
I am working on a search for SUSY particles (sleptons, sneutrinos) with cascade decays into electroweakinos that subsequently decay into the LSP and SM particles. Such processes have never been produced centrally at CMS, as far as I'm aware. I have created a request to produce them within the SUSY MC group and was asked to have the cards approved by GEN first, via a PR to this repository.
Could you please let me know if the material I have committed is sufficient for a review and if things look good?
Thanks.
