Abstract
A search for the Ξ cc + + $$ {\Xi}_{cc}^{++} $$ baryon through the Ξ cc + + $$ {\Xi}_{cc}^{++} $$ → D+pK−π+ decay is performed with a data sample corresponding to an integrated luminosity of 1.7 fb−1 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 ℛ = ℬ Ξ cc + + → D + pK − π + ℬ Ξ cc + + → Λ c + K − π + π + $$ \mathrm{\mathcal{R}}=\frac{\mathrm{\mathcal{B}}\left({\Xi}_{cc}^{++}\to {D}^{+}{pK}^{-}{\pi}^{+}\right)}{\mathrm{\mathcal{B}}\left({\Xi}_{cc}^{++}\to {\Lambda}_c^{+}{K}^{-}{\pi}^{+}{\pi}^{+}\right)} $$ with ℛ < 1.7 (2.1) × 10−2 at the 90% (95%) confidence level at the known mass of the Ξ cc + + $$ {\Xi}_{cc}^{++} $$ state.
