The study of the Quark-Gluon Plasma created in ultrarelativistic heavy-ion collisions at the CERN-LHC is complemented by reference measurements in proton-lead (p--Pb) and proton-proton (pp) collisions, where the effects of multiple-parton interactions and hadronization beyond independent string fragmentation can be investigated.

In this poster, we present a Bayesian unfolding procedure
to reconstruct the correlation between transverse momentum ($p_{\mathrm{T}} $) spectra of charged particles and the corresponding charged particle multiplicities $N_{\mathrm{ch}}$.
The unfolded spectra are presented in single multiplicity ($\Delta N_{\mathrm{ch}}$ = 1) bins and are used to derive moments of the $p_{\mathrm{T}} $ distributions.

We illustrate the unfolding procedure of the $p_{\mathrm{T}} $ spectra
with MC simulations for pp collisions and compare the resulting $\langle p_{\mathrm{T}}\rangle $ of different systems (pp, p--Pb, Pb--Pb) and collision energies.
