A search for Ξ++cc→ D+pK−π+ decays

Journal of High Energy Physics. 2019. Vol. 124. P. 1-20.

A search for the Ξ++𝑐𝑐 baryon through the Ξ++𝑐𝑐→ D+pKπ+ decay is performed with a data sample corresponding to an integrated luminosity of 1.7 fb1 recorded by the LHCb experiment in pp collisions at a centre-of-mass energy of 13 TeV. No significant signal is observed in the mass range from the kinematic threshold of the decay to 3800 MeV/c2. An upper limit is set on the ratio of branching fractions =(Ξ++𝑐𝑐𝐷+𝑝𝐾𝜋+)(Ξ++𝑐𝑐→Λ+𝑐𝐾𝜋+𝜋+) with ℛ < 1.7 (2.1) × 102 at the 90% (95%) confidence level at the known mass of the Ξ++𝑐𝑐 state.
