First measurement of $\mathrm{D_{s1}}(1^{+})(2536)^+$ and $\mathrm{D_{s2}^{*}(2^{+})(2573)^+}$ production in proton-proton collisions at $\sqrt{s} = 13$ TeV at the LHC

$\Dsone/\Ds$ (left) and $\Dstwo/\Ds$ (right) ratio times BR as a function of the average charged-particle multiplicity \avdndeta in pp collisions at $\s= 13 \TeV$ at midrapidity ($|y| 0.5$). The experimental results are compared with the theoretical predictions based on the SHM , the SHMc , PYTHIA 8 , and EPOS4HQ . The statistical and systematic uncertainties on the measured ratios are depicted as vertical lines and boxes, respectively. The theoretical uncertainty on the predicted ratios is depicted as a shaded band for the \Dsone.
