Observation of orbitally excited (L=1) B mesons

This webpage summarizes the blessed results for the observation of the orbitally excited (L = 1) B mesons in the fully reconstructed decays B+ -> J/ψ K+ (J/ψ -> μ+ μ- ) and B+ -> D0 π+ (D0 -> K+ π- ). Those have been produced for the fall conferences 2005 and have been blessed in the B Physcis Meeting on Thursday October 13, 2005.


The resulting mass measurements of this analysis are:

m(B1) = 5734 +/- 3 (stat) +/- 2 (syst) MeV/c2
m(B*2) = 5738 +/- 5 (stat) +/- 1 (syst) MeV/c2

A public note is available as: note 7938.
