Measurement of the spectroscopy of orbitally excited B mesons at LEP

Abstract: We measure the masses, decay widths and relative production rate of orbitally excited B mesons using 1.25 million hadronic Z decays recorded by the L3 detector.

“…This provides a plausible interpretation of the recently measured D * s (2860) [21] as the orthogonal partner of the mixture of conventional P wave quark-antiquark states and four-quark components describing the D * sJ (2317) [22]. In the L3 Collaboration results [9] the masses of the B * 0 and B 1 mesons, although not explicitly given, are constrained by heavy quark effective theory relations [23]…”

“…Only the ground 0 − and the excited 1 − states are well established in the PDG [8]. There are some experimental data by the L3 Collaboration [9] reporting the first measurement of the B ′ 1 and B * 2 masses, 5670±10 ± 13 MeV and 5768±5 ± 6 MeV, respectively. Recently, D0 and CDF Collaborations have reported results on the spectroscopy of orbitally excited bottom mesons [10].…”

“…Still, parts of the fit are inherently unstable, and the systematic errors are large. Furthermore, similar fits by ALEPH [8] and L3 [9] lead to different conclusions on the masses of the broad B …”
