Measurement of the W boson decay branching fraction ratio $\mathcal{B}$(W $\to$ cq) / $\mathcal{B}$(W $\to$ $\mathrm{q}{\bar{\mathrm{q}}}^{\prime }$) in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

The most precise measurement to date of the W boson hadronic decay branching fraction ratio $R_{\mathrm{c}}^{\mathrm{W}}$ = $\mathcal{B}$(W $\to$ cq) / $\mathcal{B}$(W $\to$ $\mathrm{q…
