Observation of the doubly Cabibbo-suppressed decay Ξ c + → pϕ
- Abstract:
-
The doubly Cabibbo-suppressed decay Ξ c+ → pϕ with ϕ → K + K − is observed for the first time, with a statistical significance of more than fifteen standard deviations. The data sample used in this analysis corresponds to an integrated luminosity of 2 fb −1 recorded with the LHCb detector in pp collisions at a centre-of-mass energy of 8 TeV. The ratio of branching fractions between the decay Ξ c+ → pϕ and the singly Cabibbo-suppressed decay Ξ c+ → pK − π + is measured to beℬ(Ξc+→pϕ)ℬ(Ξc+→pK−π...
