While this definition may also be used for other electromagnetic interacting particles beyond leptons and photons, the presence of the stronger nuclear interaction makes it a far less interesting characterisation of the material; the nuclear collision length and nuclear interaction length are more relevant.

Kharzeev s contributions to nuclear physics include the KLN ( Kharzeev-Levin-Nardi ) model of multi-particle production in high energy nuclear collisions, the theory of long-range forces in Quantum Chromodynamics, theory of baryon stopping, and a series of papers on anomaly-induced transport in systems with chiral fermions.

Unlike other physics experiments where a theoretical prediction can be tested directly by a single measurement, STAR must make use of a variety of simultaneous studies in order to draw strong conclusions about the QGP . This is due both to the complexity of the system formed in the high-energy nuclear collision and the unexplored landscape of the physics studied.

In an article published Monday in the journal Physical Review Letters, Dr . Donald Weingarten and his colleagues at IBM in Yorktown Heights, N . Y ., reported that numbers produced by their prodigious calculation match numbers produced over the years by certain nuclear collisions in particle accelerators, results that had not been previously identified as the signatures of glueballs.
