Abstract (data abstract)
CERN-LHC. Measurements of the transverse momenta spectra of identified charged hadrons in proton-proton collisions at centre-of-mass energies of 0.9, 2.76 and 7 TeV using data of respective integrated luminosities 0.227+-0.024 nb-1, 0.143+-0.008 nb-1 and 0.115+-0.005 nb-1. The data cover the PT range 0.1-1.7 GeV with |rapidity| < 1 with particle identification using energy loss in the silicon tracker. Fits are made to the spectra with Tsallis-Pareto-type distributions of the form: d2N/dydpt=(dN/dy).C.pt.(1+(mt-m)/nT)**-n where C=(n-1)(n-2)/(nT(nT+(n-2)m)) Tables of the fitted dN/dy, n and T are given at the end of the record.
