Entropy production in pp and Pb-Pb collisions at energies available at the CERN Large Hadron Collider

Patrick Hanus, Aleksas Mazeliauskas, Klaus Reygers

We use experimentally measured identified particle spectra and Hanbury Brown-Twiss radii to determine the entropy per unit rapidity $dS/dy$ produced in $\sqrt{s}=7$ TeV pp and $\…
