The Structure of Proton, Spin Crisis and Partonic Plasma

Abstract: Here, within the Scale-Symmetric Physics/Theory (S-ST), is presented some recapitulation concerning structure of proton. It shows that distribution of gluons described within the Quantum Chromodynamics is incorrect- there appears the spin crisis. The S-ST shows that there appear three super-dense fields composed of the carriers of gluons i.e. of the luminal Einstein-spacetime components. The three super-dense gluon fields follow from the short-distance quantum entanglement and/or confinement of the Einstein-spacetime components and they are as follows: the torus/strong-charge (its mass density is about 37 powers of ten kilograms per cubic meter; external radius is about 0.7 fm), central condensate (its mass density is about 3 times greater than 23 powers of ten kilograms per cubic meter; radius is about 0.009 fm) and relativistic pion on the S orbit (radius of the orbit is about 1.2 fm). Range of the strong interactions is about 2.9 fm. Within such model we calculated the rigorous mass, spin and two radii (the electron radius and muon radius) of proton. The torus/strong-charge is spinning and its spin is half-integral. We can compare the densities of the super-dense gluon fields with the mean mass density of proton on assumption that its radius is the range of the strong interactions: about 1.6 times greater than 16 powers of ten kilograms per cubic meter. Barbara Jacak, a professor of physics at the University of California, Berkeley, claims that the much faster than expected formation of baryonic-plasma droplets and the spin crisis follow from existence of a super-dense gluon field instead discrete gluons- it is consistent with S-ST. Here as well are calculated the fundamental quantities characteristic for partonic plasma- they are consistent with the PHENIX data. Among other things, a puzzle of anomalous enhancement of (anti)protons relative to pions is solved
