Scaling multiplicities of h-p collisions toe + e ???�+... by the Fermi-Landau law

Abstract

The similarity of rapidity distributions of hadrons frompp and\(\bar p\)p withe+e−→π±+... implies a scaling forEcm, reflecting the quark-quark interaction of particle production by\(\bar p\)/p+p. This scaling relates the meson multiplicity fromh+p→m\(\bar m\)+... to the Fermi-Landau law\(n_{ch} = a\sqrt {E_{cm} } \) fore+e− collisions, without free-parameters, threshold energy being taken into account including the mass of quarks constituent of the projectile and the target, the coefficient behaves like bremsstrahlung a∼1/m2.
