Measurement of B meson production fraction ratios in proton-proton collisions at $\sqrt{s}$ = 13 TeV using open-charm and charmonium decays

CMS Collaboration

Production fraction ratios of B${}^{+}$, B${}^0$, and B${}_{\mathrm{s}}^0$ mesons are measured in proton-proton collisions at $\sqrt{s}$ = 13 TeV using a special data set recorded in 2018 wi…
