Measurement of $π$, K, p transverse momentum spectra with ALICE in proton-proton collisions at $\sqrt{s} =$ 0.9 and 7 TeV

Results of the measurement of the $π$, K, p transverse momentum ($p_{\mathrm{t}}$) spectra at mid-rapidity in proton-proton collisions at $\sqrt{s} = 7$ TeV are presented. Particle identification was performed using the energy loss signal in the Inner Tracking System (ITS) and the Time Projection Chamber (TPC), while information from the Time-of-Flight (TOF) detector was used to identify particles at higher transverse momentum. From the spectra at $\sqrt{s} = 7$ TeV the mean transverse momentum ($ $) and particle ratios were extracted and compared to results obtained for collisions at $\sqrt{s} = 0.9$ TeV and lower energies.
