| Abstract |
The production of $varXi _{cc}^ {++}$ baryons in proton-proton collisions at a centre-of-mass energy of $sqrt{s}=13;{rm{TeV}}$ is measured in the transverse-momentum range $4 lt p_{rm{T}} lt 15;{rm{GeV}}/c$ and the rapidity range $2.0 lt y lt 4.5$. The data used in this measurement correspond to an integrated luminosity of $1.7;{rm{fb}}^{-1}$, recorded by the LHCb experiment during 2016. The ratio of the $varXi _{cc}^ {++}$ production cross-section times the branching fraction of the $varXi _{cc}^ {++} to varLambda _c^ + K^-pi^+ pi^+$ decay relative to the prompt $varLambda _c^ + $ production cross-section is found to be $(2.22pm 0.27 pm 0.29)times 10^{-4}$, assuming the central value of the measured $varXi _{cc}^ {++}$ lifetime, where the first uncertainty is statistical and the second systematic. |
