We report on the measurement of two-pion correlation functions from pp collisions at sqrt(s)=900 GeV performed by the ALICE experiment at the Large Hadron Collider. Our analysis shows an increase of theHanbury Brown–Twiss radius with increasing event multiplicity, in line with other measurements done inparticle- and nuclear collisions. Conversely, the strong decrease of the radius with increasing transversemomentum, as observed at the Relativistic Heavy Ion Collider and at Tevatron, is not manifest in our data.

Abstract
We report on the measurement of two-pion correlation functions from pp collisions at sqrt(s)=900 GeV performed by the ALICE experiment at the Large Hadron Collider. Our analysis shows an increase of theHanbury Brown–Twiss radius with increasing event multiplicity, in line with other measurements done inparticle- and nuclear collisions. Conversely, the strong decrease of the radius with increasing transversemomentum, as observed at the Relativistic Heavy Ion Collider and at Tevatron, is not manifest in our data.File in questo prodotto:
