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.
