Abstract
An amplitude analysis of the B0→ηc(1S)K+π- decays with ηc(1S)→pp¯ is performed using a sample corresponding to an integrated luminosity of 9fb-1 of pp collision data collected by the LHCb detector at centre-of-mass energies of s = 7, 8 and 13TeV. The data are described with a model including only intermediate contributions from known K∗0 resonances. Evidence for an exotic resonance in the ηc(1S)π- system, reported in a previous analysis of this decay channel, is not confirmed. The inclusive branching fraction of the B0→ηc(1S)K+π- decays is measured to be (Formula presented.) where the first uncertainty is statistical, the second systematic, and the third arises from the limited knowledge of external branching fractions.
