ttbar generation
Asked by
Sebastian Urrutia-Quiroga
Hi all,
I'm generating the SM background for a process of my interest, specifically the t tbar production with semileptonic decay for one top considering only electrons,
generate p p > t t~, (t > w+ b, w+ > j j), (t~ > w- b~, w- > e- ve~)
add process p p > t t~ j, (t > w+ b, w+ > j j), (t~ > w- b~, w- > e- ve~)
using Pythia8 for showering and Delphes for collider simulation.
I generated 10k events before matching, and I got ~4k after matching. What really puzzles me is the fact that my final ROOT file has a significant number of 0-electron events, even bigger than the number of 1-electron events.
Is this normal? If not, could you address me about how to solve the issue?
Thank you in advance,
Sebastian
