Measurement of ${\Omega }_{\mathrm{c}}^0$ baryon production and branching-fraction ratio $\mathrm{BR}({\mathrm{\Omega }}_{\mathrm{c}}^0\to {\mathrm{\Omega }}^{-}{\mathrm{e}}^{+}{\nu }_{\mathrm{e}})/\mathrm{BR}({\mathrm{\Omega }}_{\mathrm{c}}^0\to {\mathrm{\Omega }}^{-}{\pi }^{+})$ in pp collisions at $\sqrt{s}$ = 13 TeV

ALICE Collaboration

The inclusive production of the charm-strange baryon ${\Omega }_{\mathrm{c}}^0$ is measured for the first time via its semileptonic decay into ${\Omega }^{-}{\mathrm{e}}^{+}{\nu }_{\mathrm{e}}$ at midrapidity ($|y|<0.8$)…
