Abstract

The energy dependence of total cross section of hadron-nucleon collisions has been studied in terms of two components: the first component decreases with increasing energy of the incident hadron whereas the second component increases like ln s. The coefficient of ln s is found to be the same within 5% for p ±p, π ±p and K ±p collisions. The rate of growth of the rising component i.e., d σ /d(ln, s), of inelastic cross sections, deduced from σ tot and σ el, of pp and πp are found to be the same within 1.5 standard deviations; an attempt has been made to understand this near equality from factorization of the pomeron.
