# Temperature oscillations and sound waves in hadronic matter

## TL;DR

This paper suggests that observed log-periodic oscillations in particle momentum distributions at CERN LHC may indicate the presence of sound waves in the high-density matter produced during collisions, offering new insights into the production process.

## Contribution

It introduces the idea that small oscillations in particle distribution ratios can reveal sound wave phenomena in hadronic matter.

## Key findings

- Log-periodic oscillations observed in data
- Potential interpretation as sound waves in produced matter
- New method to probe collision dynamics

## 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.
