Protons reveal universal phenomenon of maximal entanglement

When a high-energy photon strikes a proton, secondary particles diverge in a way that indicates that the inside of the proton is maximally entangled. An international team of physicists with the participation of the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow has just demonstrated that maximum entanglement is present in the proton even in those cases where pomerons are involved in the collisions.
