      abstract     = {We consider an observable very sensitive to the non-zero
                      intrinsic charm (IC) contribution to the proton density. It
                      is the ratio between the differential cross sections of the
                      photon or $Z$-boson and $c$-jet production in the $pp$
                      collision, $\gamma(Z) + c$, and the $\gamma(Z)$ and the
                      $b$-jet production. It is shown that this ratio can be
                      approximately flat or increasing at large $\gamma(Z)$
                      transverse momenta $p_T$ and their pseudo-rapidities $1.5 <
                      \eta < 2.4$ if the IC contribution is taken into account. On
                      the contrary, in the absence of the IC this ratio decreases
                      as $p_T$ grows. We also present the ratios of the cross
                      sections integrated over $p_T$ as a function of the IC
                      probability $w$. It is shown that these ratios are mostly
                      independent on the theoretical uncertainties, and such
                      predictions could therefore be much more promising for the
                      search for the intrinsic charm signal at the LHC compared to
                      the predictions for $p_T$-spectra, which significantly
                      depend on these uncertainties.},
