High Enerty Phenomenology

Abstract

Man has always been very keen to unravel the mysteries of nature and his effort to understand what we are made of is one of the greatest adventure stories of the human race. In fact nothing has surpassed his curiosity to learn the nature of elementary particulars which may serve as the building blocks of matter. The study of two-body hadronic reactions at high energies can give an insight into the nature of these particles. The construction of machines producing high energy particles has opened a new era. The hadronic reactions at various high energies have been studied. During these three years, we have tried to explain the various experimental results concerning the angular distribution. Since there does not exists any dynamic theory of elementary particles, attempts have been made to give piecemeal explanations of various experimental results. The phenomenological picture of high-energy two-body or quasi-two-body process is at present strongly dominated by Regge theory. The analysis of scattering amplitudes in terms of the quantum numbers exchange in the crossed channel has provided a deep insight into the high-energy behavior of these reaction mechanisms. We have used the Dual Absorptive Model, the Eikonal Model and the Reggeon Calculus to explain the differential cross section for pp~pp, KP~Kp,TP~PT and many other reactions. Every effort was made to interpret the most recent data on these models. Nine research papers were published during this period and our contribution may be of some help in having a better understanding of the nature of hadronic interactions.
