Partonic origin of the universal scaling of charged particle pseudorapidity distribution in e~+e~-, p(p)+p and Au+Au collisions

摘要

1. Universal scaling of the charged particle pseudorapidity distribution seems having its partonic origin; 2. Of course, much remains to be done after preliminary results; 3. Howevger, above scaling is observed in the tail region Small distinctions among small observables, easy to be hided 4. That scaling, not so hard to be repeated, not so much things to do with physics, probably.
