This thesis reports first measurements of K$^*$(892)$^{\pm}$ produced in pp collisions at $\sqrt{s} = 13$~TeV as function of the event multiplicity. The results include, for each multiplicity class considered, the differential transverse momentum ($p$\textsubscript{T}) spectrum, the mean transverse momentum $\langle p$\textsubscript{T}$\rangle$, the integrated yield (d$N$/d$y$), and the ratio of the K$^*$(892)$^{\pm}$ yield to the K$^0_{\rm S}$ one. The K$^*$(892)$^{\pm}$ has been studied at the same energy and compared with the neutral K$^*$ resonance production, as well as with results from different event generators.
