  "abstract": "<p>Multiplicity (${N}_{\\mathrm{ch}}$) distributions and transverse momentum (${p}_{T}$) spectra of inclusive primary charged particles in the kinematic range of $|\\eta |&lt;0.8$ and $0.15\\text{GeV}/c&lt;{p}_{T}&lt;10\\text{GeV}/c$ are reported for pp, p\u2013Pb, Xe\u2013Xe and Pb\u2013Pb collisions at centre-of-mass energies per nucleon pair ranging from $\\sqrt{{s}_{\\mathrm{NN}}\\phantom{\\rule{0.2em}{0ex}}}=2.76\\text{TeV}$ up to 13 TeV. A sequential two-dimensional unfolding procedure is used to extract the correlation between the transverse momentum of primary charged particles and the charged-particle multiplicity of the corresponding collision. This correlation sharply characterises important features of the final state of a collision and, therefore, can be used as a stringent test of theoretical models. The multiplicity distributions as well as the mean and standard deviation derived from the ${p}_{T}$ spectra are compared to state-of-the-art model predictions. Providing these fundamental observables of bulk particle production consistently across a wide range of collision energies and system sizes can serve as an important input for tuning Monte Carlo event generators.</p>",
