Abstract: In ultra-high energy nuclear collisions at center of mass
energies 0.2 - 2.76 TeV per nucleon pair, a new state of strongly
interacting matter called the Quark Gluon Plasma (QGP) - magyarul
"ragacsos túró" - is created [1].
The most amazing property of this new state of matter is that it
seems to flow more perfectly than even 4 K super-fluid Helium! Its
viscosity appears to reach the  lower bound set by the uncertainty
principle and string theory. However, recent data on proton + Lead
reactions from the LHC have posed a "puzzle" because the harmonic
flow patterns observed in p+Pb were unexpectedly found to be nearly
identical to those observed in the much larger Pb+Pb systems. I will
review current theoretical ideas and debates contrasting Standard
Model Quantum Chromodynamics, Holographic (AdS/CFT) Gravity Dual, and
Scintillating Color String models proposed to resolve current puzzles
from nuclear reactions at LHC energies.
