Sound waves in hadronic matter

  title={Sound waves in hadronic matter},
  author={Grzegorz Wilk and Zbigniew Włodarczyk},
We argue that recent high energy CERN LHC experiments on transverse momenta distributions of produced particles provide us new, so far unnoticed and not fully appreciated, information on the underlying production processes. To this end we concentrate on the small (but persistent) log-periodic oscillations decorating the observed p T spectra and visible in the measured ratios R = σ data (p T ) / σ fit (p T ) . Because such spectra are described by quasi-power-like formulas characterised by two…

System size dependence of the log-periodic oscillations of transverse momentum spectra

Recently the inclusive transverse momentum distributions of primary charged particles were measured for different centralities in Pb + Pb collisions. A strong suppression of the nuclear modification

Tsallis Distribution Decorated with Log-Periodic Oscillation

It is argued that such a factor can originate from allowing for a complex nonextensivity parameter $q$ and the possible information conveyed by such an approach will be discussed.

Multiplicity and transverse momentum fluctuations in inelastic proton–proton interactions at the CERN Super Proton Synchrotron

Measurements of multiplicity and transverse momentum fluctuations of charged particles were performed in inelastic p+p interactions at 20, 31, 40, 80, and 158 $$\text{ GeV }\!/\!c$$GeV/c beam

Hot strong matter

The recent results on relativistic heavy-ion collisions are discussed. The most convincing quark-gluon plasma signatures at the LHC and the top RHIC energies are presented. Moreover, the possible

A ‘soft + hard’ model for heavy-ion collisions

We describe the spectra of neutral pions stemming from AuAu collisions at s=200 AGeV in a ‘soft + hard’ model. The model is based on the assumptions that hadrons stemming from hard processes are

Onset of deconfinement in nucleus-nucleus collisions: Review for pedestrians and experts

Evidence for the energy threshold of creating the quark-gluon plasma in nucleusnucleus collisions, the so-called onset of deconnement, has been found by the energy scan program of the NA49 experiment

Statistical Mechanics:

AbstractPROF. R. H. FOWLER'S monumental work on statistical mechanics has, in this the second edition, in his own modest words, been rearranged and brought more up to date. But the new volume is much
