First observation of the decay D0 → K−π+μ+μ− in the ρ0–ω region of the dimuon mass spectrum
- Abstract:
-
.A study of the decay D0 → K-π+μ+μ-is performed using data collected by the LHCb detector in proton-proton collisions at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 2.0 fb^-1. Decay candidates with muon pairs that have an invariant mass in the range 675-875 MeV/c2 are considered. This region is dominated by the ρ0 and ω resonances. The branching fraction in this range is measured to B(D0 → K-π+μ+μ-) = (4.17 ± 0.12(stat) ± 0.40(syst))×10^-6. This is the first...

) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
Content may be unavailable for the following four reasons
-
Version unsuitable
-
We have not obtained a suitable full-text for a given research output. See this page for more information.
-
