    Scaling violations: Connections between elastic and inelastic hadron scattering in a geometrical approach

    Get PDF
    Starting from a short range expansion of the inelastic overlap function, capable of describing quite well the elastic pp and pˉp\bar{p}p scattering data, we obtain extensions to the inelastic channel, through unitarity and an impact parameter approach. Based on geometrical arguments we infer some characteristics of the elementary hadronic process and this allows an excellent description of the inclusive multiplicity distributions in pppp and pˉp\bar{p}p collisions. With this approach we quantitatively correlate the violations of both geometrical and KNO scaling in an analytical way. The physical picture from both channels is that the geometrical evolution of the hadronic constituents is principally reponsible for the energy dependence of the physical quantities rather than the dynamical (elementary) interaction itself.Comment: 16 pages, aps-revtex, 11 figure
