TTTT Analysis

This Notebook is simply a playground to examine the resulting histograms from the main TTTT analysis executable.

import ROOT
from IPython.display import display, display_markdown
%load_ext autoreload
%autoreload 2

from utils import HistCollection as HC
from utils import clear, show_event, show_value, normalize_columns, CANVAS, PDG

The autoreload extension is already loaded. To reload it, use:
  %reload_ext autoreload

First, we need to load the pre-processed datafiles. These will generally contain a set of histograms of various quantities calculated from data in the input MiniTrees. However, they can also contain things besides histograms. For example, C++ STL containers can be serialized to the ROOT file to save things such as counters or even "raw" event information.

TTW_event = show_event(hists_TTW, event_number)
TTTT_event = show_event(hists_TTTT, event_number)

We can use the show_event function to look at the Generator-Level particles for the event. They are color-coded based on their pt relative to the maximum pt of a particles in the event. Darker is lower, greener/lighter is higher. The following are the particle trees for event #9 in each dataset.

  • TTZ Generator-Level Particles
  • TTW Generator-Level Particles
  • TTTT Generator-Level Particles
