The inclusive charged particle transverse momentum distribution is measured in proton-proton collisions at $\sqrt{s} = 900$ GeV at the LHC using the ALICE detector. The measurement is performed in the central pseudorapidity region $(| η | < 0.8)$ over the transverse momentum range $0.15 < p_{T} < 10$ GeV/ $c$ . The correlation between transverse momentum and particle multiplicity is also studied. Results are presented for inelastic (INEL) and non-single-diffractive (NSD) events. The average transverse momentum for $| η | < 0.8$ is ${⟨ p_{T} ⟩}_{I N E L} = 0.483 \pm 0.001$ (stat.) $\pm 0.007$ (syst.) GeV/ $c$ and ${⟨ p_{T} ⟩}_{N S D} = 0.489 \pm 0.001$ (stat.) $\pm 0.007$ (syst.) GeV/ $c$ , respectively. The data exhibit a slightly larger $⟨ p_{T} ⟩$ than measurements in wider pseudorapidity intervals. The results are compared to simulations with the Monte Carlo event generators PYTHIA and PHOJET.
