      abstract     = {A search for the standard model Higgs boson decaying to a
                      charm quark-antiquark pair, H $\to \mathrm{c\bar{c}}$,
                      produced in association with a leptonically decaying V (W or
                      Z) boson is presented. The search is performed with
                      proton-proton collisions at $\sqrt{s}$ = 13 TeV collected by
                      the CMS experiment, corresponding to an integrated
                      luminosity of 138 fb$^{-1}$. Novel charm jet identification
                      and analysis methods using machine learning techniques are
                      employed. The analysis is validated by searching for Z $\to
                      \mathrm{c\bar{c}}$ in VZ events, leading to its first
                      observation at a hadron collider with a significance of 5.7
                      standard deviations. The observed (expected) upper limit on
                      $\sigma$(VH)$\mathcal{B}$(H$\to \mathrm{c\bar{c}}$) is 0.94
                      (0.50$^{+0.22}_{-0.15}$) pb at 95\% confidence level (CL),
                      corresponding to 14 (7.6$^{+3.4}_{-2.3}$) times the standard
                      model prediction. For the Higgs-charm Yukawa coupling
                      modifier, $\kappa_\mathrm{c}$, the observed (expected) 95\%
                      CL interval is 1.1 $\lt\vert\kappa_\mathrm{C}\vert \lt$ 5.5
                      ($\vert\kappa_\mathrm{c}\vert\lt$ 3.4), the most stringent
                      constraint to date.},
