Adiabatic expansion, local equilibrium and extended Maxwell distribution for fire-ball to describe multiple particle production (II)

Akinori Ohsawa

The model of multiple particle production in [A. Ohsawa, Int. J. Mod. Phys. A (2023) 2350166.] assumes a fire-ball of a gas, consisting of grains, with the adiabatic and one-dimensional expansion, local equilibrium at the final state and the extended Maxwell distribution …

Adiabatic expansion, local equilibrium and extended Maxwell distribution for fire-ball to describe multiple particle production

Akinori Ohsawa

We propose a model for multiple particle production of [Formula: see text] and [Formula: see text] collisions at high energies. Most of the processes in the model are reasonable physically and/or with reasoning. A fire-ball of a gas, made of grains, is …

Adiabatic expansion of nuclear matter gas to describe violation of Feynman scaling law in multiple particle production

Akinori Ohsawa, Edison Hiroyuki Shibuya, M. Tamada

The main features of the rapidity density distribution of the produced hadrons in multiple particle production in nucleon collisions are; (a) the distribution in the forward region (ȳ ≥ 0) has a shape similar to the Fermi distribution, (b) the distribution in …

An empirical model to describe rapidity density and transverse momentum distributions

Akinori Ohsawa, Edison Hiroyuki Shibuya, M. Tamada

The distribution of rapidity density and transverse momentum is formulated empirically and analytically. It describes the data quite well over the wide energy range of √s = 22.4 – 7000 GeV.

DESCRIPTION OF (PSEUDO-)RAPIDITY DENSITY AND TRANSVERSE MOMENTUM DISTRIBUTIONS IN A WIDE ENERGY RANGE $(\sqrt{s} = 22.4\hbox{--}7000~{\rm GeV})$

Akinori Ohsawa, Edison Hiroyuki Shibuya, M. Tamada

The rapidity density and transverse momentum distributions of produced particles in multiple particle production are formulated assuming that the produced particles are emitted isotropically from several emitting centers. The energy distribution of produced particles in the rest frames of respective emitting centers …

Phenomenological Approach to Multiple Particle Production

Akinori Ohsawa, E. H. Shubuya, M. Tamada

We formulate empirically the rapidity density distribution of produced particles in multiple particle production. The assumed mechanism is that the produced particles are emitted isotropically from several emitting centers, located on the rapidity axis. The formula includes five adjustable parameters, which are …

Empirical formulation of rapidity density distribution in multiple particle production in a wide energy range from fixed target to LHC

Akinori Ohsawa, Edison Hiroyuki Shibuya, M. Tamada

We formulate empirically the rapidity density distribution of produced particles in multiple particle production. We assume several emitting centers, distributed on the rapidity axis, from which the produced particles are emitted isotropically with energy distributed in the inverse-exponential form. The formula includes …

The exotic characteristics of centauro-I: a model to describe Centauro-I

Akinori Ohsawa, Edison Hiroyuki Shibuya, M. Tamada

In our previous paper on Centauro-I (Ohsawa et al 2004 Phys. Rev. D 70 074028), we showed that the shower cluster, found in the block I12 of the lower chamber, is produced in the target layer by a number of hadrons with …
