The problem is that here, if you are not "into the project" (i.e. having read the 5-6 preceding posts and having their content in mind), anything beyond the first paragraph is probably obscure. I cannot summarized the previous episode in more details for the simple reason of the post becoming just too huge.
For this project, simulations matter but they will come later. What we aim, at the end of the day, is to simulate any signal for any theory and check how well (or how bad) the LHC could find them.
Does it make things clearer? :)
