Measurement of the shape of the Λ0b→Λ+cμ−νμ¯ differential decay rate

Abstract:

A measurement of the shape of the differential decay rate and the associated Isgur-Wise function for the decay Λ0b→Λ+cμ−¯νμ is reported, using data corresponding to 3  fb^−1 collected with the LHCb detector in proton-proton collisions. The Λ+cμ−¯νμ(+anything) final states are reconstructed through the detection of a muon and a Λ+c baryon decaying into pK−π+, and the decays Λ0b→Λ+cπ+π−μ−νμ¯ are used to determine contributions from Λ0b→Λ*+cμ−ν¯ μ decays. The measured dependence of the different...
