Two-component Pomeron and hadron total cross sections

Description

The two-component structure of the so-called Pomeron is investigated in total cross sections of hadrons. The overlap function is decomposed into several ingredients in reference to the quarkline diagrams which represent hadron-hadron to Reggeon-Reggeon scattering. The second component of Pomeron is due to the ingredient which is related to H and X type diagrams connected with nonstrange meson exchange, while the first one is due to D type diagrams. The two components of Pomeron are estimated from πN and KN total cross section data at NAL energies; the first component increases slowly while the second one decreases slowly with energy. Data on pp give 1.57 as ratio of the first component in NN to πN and KN, and 3.46 as that of the second one in NN to KN. Hyperon-nucleon total cross sections are predicted. Total cross section of pp scattering is calculated and compared with experimental data in ISR energy region. Several cases are considered for the energy dependence of Pomerons. The case that the first component increases as ln p sub(L) and the second one decreases to a finite value as energy increases brings the best fit to present data. (auth.)
