This paper presents a study on the coherent meson production in 12C–emulsion interactions at 4.5 Gev∙c−1∙nucleon−1 incident momentum. The search for coherence was done through noting the shape of the multiplicity distribution in different narrow rapidity bins and observing whether or not the distribution was according to Poisson; when the fields are completely coherent the multiplicity should have a Poisson distribution. It was observed that the multiplicity distribution was Poisson in nature in two bins of higher rapidity, and consequently the field was coherent in those rapidity bins. The percentage of coherent meson production was estimated to be 48%.

This work involves hard photon rate production from quark -gluon plasma QGP interaction in heavy ion collision. Using a quantum chromodynamic model to investigate and calculation of photons rate in 𝑐𝑔 → 𝑠𝑔𝛾 system due to strength coupling, photons rate, temperature of system, flavor number and critical. The photons rate production computed using the perturbative strength models for QGP interactions. The strength coupling was function of temperature of system, flavor number and critical temperature. Its influenced by force with temperature of system, its increased with decreased the temperature and vice versa. The strength coupling has used to examine the confinement and deconfinement of quarks in QGP properties and influence on the photon rate production. In our approach, we calculate the photons rate depending on the strength coupling, photons rate and temperature of system with other factors. The results plotted as a function of the photons energy. The photons rate was decreased with increased temperature and increased with decreased with strength coupling.

An overview of a hadron resonance gas (HRG) model that includes van der Waals (vdW) interactions between hadrons is presented. Applications of the excluded volume HRG model to heavy-ion collision data and lattice quantum chromodynamics (QCD) equation of state are discussed. A recently developed quantum vdW HRG model is covered as well. Applications of this model in the context of the QCD critical point are elaborated.
