Název v původním jazyce

Self-similarity of Proton Spin

Popis výsledku v původním jazyce

Origin of spin is one of fundamental mysteries of nature. Spin of proton itself and of point-like quarks is equal to 1/2h. Composition of the proton spin from spins of quarks, gluons and processes including formation and annihilation of the quark-antiquark pairs indicate on a repeated pattern in the internal spin structure over a wide scale range. New hypothesis of self-similarity of the proton spin composition is suggested and discussed. The concept of z-scaling previously developed for analysis of inclusive reactions is applied for description of processes with polarized particles. Generalized characteristics of proton spin structure, namely the spin-dependent fractal dimensions, are suggested. Possibilities to extract information on these quantitiesfrom double spin asymmetries are discussed. New high-precision RHIC data on the asymmetries in polarized proton-proton collisions are analyzed in the framework of the z-scaling. Information on spin-dependent fractal dimensions of proton
