Summary II:

Baryon Junction dynamics in HIJING BB2.0 predictsDrastically different global entropy dNch / dy~ 3000-4000 , dNp / dy~ 200

Due to abundance of extra J-Jbar 3 string loopsAnd strong longitudinal color fields (ropes)as currently parametrized

The probability of exciting J Jbar junctionsIn A+A at LHC is an open question

Comparing baryon and meson observablesCan set a bound of junction formation
