First observation of a baryonic Bc+ decay.
A baryonic decay of the B(c)(+) meson, B(c)(+) → J/ψppπ(+), is observed for the first time, with a significance of 7.3 standard deviations, in pp collision data collected with the LHCb detector and corresponding to an integrated luminosity of 3.0 fb(-1) taken at center-of-mass energies of 7 and 8 TeV. With the B(c)(+) → J/ψπ(+) decay as the normalization channel, the ratio of branching fraction...
متن کاملFirst observation of the decay Ds+-->pn.
Using e+e--->Ds*-Ds+ data collected near the peak Ds production energy, Ecm=4170 MeV, with the CLEO-c detector, we present the first observation of the decay Ds+-->pn. We measure a branching fraction B(Ds+-->pn)=(1.30+/-0.36(-0.16)+0.12)x10(-3). This is the first observation of a charmed meson decaying into a baryon-antibaryon final state.
متن کاملFirst Observation of the Decay τ − → φK − ν τ
We present the first observation of τ lepton decays to hadronic final states with a φ-meson. This analysis is based on 401 fb of data accumulated at the Belle experiment. The branching fraction obtained is B(τ− → φK−ντ ) = (4.05 ± 0.25 ± 0.26) × 10.
متن کاملFirst observation of ground state dineutron decay: 16Be.
We report on the first observation of dineutron emission in the decay of 16Be. A single-proton knockout reaction from a 53 MeV/u 17B beam was used to populate the ground state of 16Be. 16Be is bound with respect to the emission of one neutron and unbound to two-neutron emission. The dineutron character of the decay is evidenced by a small emission angle between the two neutrons. The two-neutro...
