Observation of Baryons in $B$ Meson Decay

The CLEO collaboration Alam, M.S. ; Csorna, S.E. ; Garren, L. ; et al.
Phys.Rev.Lett. 51 (1983) 1143, 1983.
Inspire Record 190324 DOI 10.17182/hepdata.20526

In a sample of B mesons from the decay of the ϒ(4S) produced in e+e− collisions at the Cornell Electron Storage Ring, inclusive protons, antiprotons, lambdas, and antilambdas have been observed. Lower limits to the B-to-baryon branching ratios are derived.

Inclusive electron Production in e+ e- Annihilation at 29-GeV

Nelson, M.E. ; Blondel, A. ; Trilling, G. ; et al.
Phys.Rev.Lett. 50 (1983) 1542, 1983.
Inspire Record 188964 DOI 10.17182/hepdata.38161

The total momentum and transverse momentum spectra of electrons in e+e− annihilation at 29 GeV have been measured. The inclusive cross section is determined to be 14.4±1.6±5.2 pb for momenta greater than 2 GeV/c. The average semielectronic branching ratios of charm and bottom quarks are measured to be (6.3±1.2±2.1)% and (11.6±2.1±1.7)%, respectively. The fragmentation function for bottom quarks is determined to be peaked at high z, with 〈z〉b=0.75±0.05±0.04.

DECAY OF B MESONS INTO CHARGED AND NEUTRAL KAONS

The CLEO collaboration Brody, A. ; Chen, A. ; Goldberg, M. ; et al.
Phys.Rev.Lett. 48 (1982) 1070-1074, 1982.
Inspire Record 180612 DOI 10.17182/hepdata.27749

Data on inclusive kaon production in e+e− annihilations at energies in the vicinity of the ϒ(4S) resonance are presented. A clear excess of kaons is observed on the ϒ(4S) compared to the continuum. Under the assumption that the ϒ(4S) decays into BB¯, a total of 3.38±0.34±0.68 kaons per ϒ(4S) decay is found. In the context of the standard B-decay model this leads to a value for (b→c)(b→all) of 1.09±0.33±0.13.
