Based on the model of nuclear-collision geometry, the independent N–N collision picture and participant contribution picture are used to describe the transverse-energy distribution in p–A collisions at high energy. In the independent N–N collision picture, the energy loss of leading proton in each p–N collision is considered. The calculated results are in agreement with the experimental data of p–Al, p–Cu, and p–U collisions at 200 GeV/c. PACS Nos.: 13.85-t, 13.85Hd, 25.75-q

We extend to investigate photon production through annihilation with scattering (AWS), and Compton and annihilation processes from a stabilized high energy nuclear collision of quark–gluon plasma (QGP) incorporating finite value of quark mass obtained through a strong coupling value. The production rate is represented in the region of low and intermediate photon energy and it is observed to be a decreasing function with temperature. The calculation is extended to the case of photon spectra with the photon transverse momentum. The current observation shows little enhancement in both processes at the temperature T = 0.25 GeV and it is in conformity with the recent direct photon production of other works at temperature T = 0.30 GeV .

Transverse energy distributions have proved to be useful in the understanding of reaction mechanisms of relativistic heavy ion interactions. The development of the subject is traced from its roots in elementary particle physics. A review and analysis of the data from recent measurements in high energy heavy ion beams at CERN and Brookhaven is presented.

We review the charged particle and photon multiplicities and transverse energy production in heavy-ion collisions starting from few GeV to TeV energies. The experimental results of pseudorapidity distribution of charged particles and photons at different collision energies and centralities are discussed. We also discuss the hypothesis of limiting fragmentation and expansion dynamics using the Landau hydrodynamics and the underlying physics. Meanwhile, we present the estimation of initial energy density multiplied with formation time as a function of different collision energies and centralities. In the end, the transverse energy per charged particle in connection with the chemical freeze-out criteria is discussed. We invoke various models and phenomenological arguments to interpret and characterize the fireball created in heavy-ion collisions. This review overall provides a scope to understand the heavy-ion collision data and a possible formation of a deconfined phase of partons via the global observables like charged particles, photons, and the transverse energy measurement.
