Temperature oscillations and sound waves in hadronic matter

Abstract

Recent high energy CERN LHC experiments on transverse momenta distributions of produced particles seem to show the existence of some (small but persistent) log-periodic oscillation in the ratios $R={\sigma }_{data}\left(p_T\right)/{\sigma }_{fit}\left(p_T\right)$. We argue that they can provide us with so far unnoticed information on the production process, which can be interpreted as the presence of some kind of sound waves formed during the collision process in the bulk of the produced high density matter.
