## Geometrical scaling in hadronic collisions

### Abstract

We show that the p_T spectra measured in pp collisions at the LHC exhibit geometrical scaling introduced earlier in the context of deep inelastic scattering. We also argue that the onset of geometrical scaling can be seen in nucleus-nucleus collisions at lower RHIC energies.Comment: 10 pages, 5 figures, based on a talk presented at Cracow Epiphany Conference "On the First Year of the LHC", Krakow, January 10-12, 2011.
