The data used in this measurement correspond to an integrated luminosity of 1.7 $fb^{-1}$, recorded by the LHCb experiment during 2016. The ratio of the $\mathit{\Xi}_{cc}^{++}$ production cross-section times the branching fraction of the $\mathit{\Xi_{cc}^{++} \to \Lambda_{c}^{+} K^- \pi^+ \pi^+}$ decay relative to the prompt $\mathit{\Lambda_c^{+}}$ production cross-section is found to be $(2.22\pm 0.27 \pm 0.29)\times 10^{-4}$, assuming the central value of the measured $\mathit{\Xi_{cc}^{++}}$ lifetime, where the first uncertainty is statistical and the second systematic.12 p.application/pdfengcc-by (c) Aaij, R. et al., 2019http://creativecommons.org/licenses/by/3.0/es/Col·lisions (Física)BarionsQuarksCollisions (Physics)BaryonsQuarksinfo:eu-repo/semantics/article7062232021-03-03info:eu-repo/semantics/openAccess
