N2 - A measurement of the $ {\varXi}_{cc}^{++} $ mass is performed using data collected by the LHCb experiment between 2016 and 2018 in pp collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.6 fb$^{−1}$. The $ {\varXi}_{cc}^{++} $ candidates are reconstructed via the decay modes $ {\varXi}_{cc}^{++}\to {\varLambda}_c^{+}{K}^{-}{\pi}^{+}{\pi}^{+} $ and $ {\varXi}_{cc}^{++}\to {\varXi}_c^{+}{\pi}^{+} $. The result, 3621.55 ± 0.23 (stat) ± 0.30 (syst) MeV/c$^{2}$, is the most precise measurement of the $ {\varXi}_{cc}^{++} $ mass to date.[graphic not available: see fulltext]
