Additional information required for recasting and validation: |

| LLP efficiencies mainly applied on GEN objects and their daughters. Usually done through tracing daughters in hepmc or Delphes GEN information. For the Delphes case, including the whole GEN collection leads to extremely large files, and tracing daughters can be tricky (due to radiation and showering). | LLP efficiencies mainly applied on GEN objects and their daughters.

| - | Propose having a module that filters LLPs and their daughters from the Delphes GEN branch and saves them in the Delphes output. Andre has an existing module. Plan to make it available for public use, and further, discuss with the Delphes team the possibility to make it a recognized part of Delphes releases. Disappearing track ADL will be built based on this output. | + | Propose having a module that filters LLPs and their daughters from the Delphes GEN branch and saves them in the Delphes output.
