Fire-Balls and Accelerator Experiments

Abstract

The energy of accelerator has been increasing and already come to 300 GeV at NAL and 1,500 GeV at CERN machine. These large proton ac­ celerators are offering a large number of and various kinds of data on the multiple production of tnesons in high energy regions, which have been offered till the present only by the cosmic-ray experiments. The cosmic-ray experiments already gave indication for the existence of a spherical fire-ball with constant mass and temperature as the intermediate product of the multiple production of mesons.1),2) The authors made a fire­ ball study with the bubble chamber film on 10 GeV 7T--p collisions and with the emulsion stacks exposed to 24 Ge V proton beam, and the results showed existence of a spherical fire-ball of mass -2.4· GeV.3) From the above results it becomes highly probable that a fire-ball is playing an essential role for the multiple meson production over a wide range of energies, i.e., from about 10 GeV up to around 100,000 GeV.2),3) Further­ more, the physical properties of a fire-ball, such as its rest energy and temper­ ature, appear to remain constant, and increase of available energy is causing increase of velocity and number of produced fire-balls. These features are consistent with the H-quantum model. 4 > Because of importance of the conclusion and the information from the large accelerators being now available, the authors made a general survey over the published results on the multiple meson production from the acceler­ ator experiments, on the basis of the hypothesis of a fire-ball of constant mass and temperature. The results show that all the available data are in good consistency with the hypothesis and Serpukhov, NAL and CERN experiments are covering the region of production of two, three, four or more fire-balls.
