[Recorded on 05.14.2019] Continuing on with the Pythia6 and Pythia8 track comparisons... Here's the last iteration:

While the last time I took the ratio between Pythia8 and Pythia6 and the ratio between pi0-triggers and hadron-triggers, this time I take the ratio between particle-level and detector-level (and vice versa) for each situation (Pythia6 pi0-triggers, Pythia6 hadron-triggers, etc.). So here are the particle-to-detector ratios:

Now, note how far the Pythia8 ratio is above the Pythia6 ones... This is because I accidentally included neutral particles in the particle-level of Pythia8. So to get an idea of what it should look like with only charged particles, I scaled the particle level by 2/3. Here are the scaled Pythia8 comparisons:

Since we're used to looking at efficiencies, it's a bit easier to compare if we look at detector-to-particle ratios. Here are the comparisons with those ratios:
