Angular analysis for $B_s^0 \rightarrow \phi \mu^+\mu^-$ at 13 TeV

Introduction

This is a dedicated Twiki page for the BPH-**-*** analysis: Angular analysis for $B_s^0 \rightarrow \phi \mu\mu$ decay with the CMS experiment in pp collisions at sqrt(s) = 13 TeV. Analysis note can be found at AN-18-068

Guidelines

This table serves as to-do list and to collect all material (links to it) in one place.
Rows hopefully proceed from sign up to do it to ongoing to done.
Names in parentheses indicate persons who have expressed interest in a topic, but not with top priority. So if you feel like doing one of these, just do it even if somebody else's parenthetical name is present.

  • The below table shows the unique sequence in the file names for each year. This will help you find the correct file name along with the path.
  • If multiple files present containing the same sequence then they are to be added to TChain
  • RECO level events available in TTree named tree
  • GEN level events for official MC samples are in same files within the TTree named gentree
