Reminder of relevant hadrons (I really needed it)
Hadron | Mass [MeV] | Content |
φ | 1020 | ssbar |
η | 548 | uubar+ddbar-2ssbar |
η' | 958 | uubar+ddbar+ssbar |
ρ | 770 | udbar, uubar, ddbar |
ω | 782 | uubar, ddbar |
Data
Data taken in 2017 & 2018 use the BLS stream in addition to the main stream, which writes out events at around 200Hz and reconstructs them on a delayed timeline.

Code
The Gitlab repository for the code I have so far is here:

There are instructions on how to use the cutflow and the plotting code in the respective readme.
