Model-independent evidence for J/ψp contributions to Λb0 → J/ψpK- decays.

Abstract:

The data sample of Λb0 → J/ψpK- decays acquired with the LHCb detector from 7 and 8 TeV pp collisions, corresponding to an integrated luminosity of 3  fb^-1, is inspected for the presence of J/ψp or J/ψK- contributions with minimal assumptions about K-p contributions. It is demonstrated at more than nine standard deviations that Λ0b → J/ψpK- decays cannot be described with K-p contributions alone, and that J/ψp contributions play a dominant role in this incompatibility. These model-independen...
