Cross Section
- The B meson cross section is determined using
- Where:
- N is the number of B mesons from a unbinned likelihood fit
- ?pT is the width of the pT bin
- L? is the corrected integrated luminosity
- A is the MC acceptance which included the trigger efficiency.
- ? is the reconstruction efficiency
- B=BR(B+ ? J/?K+) ? BR(J/? ? ?+?-)=(5.88?0.60) ?10-5
