The first interesting findings from LHC have been reported. The full article is here. In some proton-proton collisions more than hundred p"/public_html/articles/ are produced suggesting a single object from which they are produced. Since the density of matter approaches to that observed in heavy ion collisions for five years ago at RHIC, a formation of quark gluon plasma and its subsequent decay is what one would expect. The observations are not however quite what QCD plasma picture would allow to expect. What is so striking is the evolution of long range correlations between p"/public_html/articles/ in events containing more than 90 p"/public_html/articles/ as the transverse momentum of the p"/public_html/articles/ increases in the range 1-3 GeV (see the excellent description of the correlations by Lubos).
One studies correlation function for two p"/public_html/articles/ as a function of two variables. The first variable is the difference Δ φ for the emission angles and second is essentially the difference for the velocities described relativistically by the difference Δ η for hyperbolic angles. As the transverse momentum pT increases the correlation function develops structure. Around origin of Δ η axis a widening plateau develops near Δ Φ=0. Also a wide ridge with almost constant value as function of Δ η develops near Δ φ=π. What this means that p"/public_html/articles/ tend to move collinearly and or in opposite directions. In the latter case their velocity differences are large since they move in opposite directions so that a long ridge develops in Δ η direction.
Ideal QCD plasma would predict no correlations between p"/public_html/articles/ and therefore no structures like this. The radiation of p"/public_html/articles/ would be like blackbody radiation with no correlations between photons. The description in terms of string like object proposed also by Lubos on basis of analysis of the graph showing the distributions as an explanation of correlations looks attractive. The decay of a string like structure producing p"/public_html/articles/ at its both ends moving nearly parallel to the string to opposite directions could be in question.
Since the densities of p"/public_html/articles/ approach those at RHIC, I would bet that the explanation (whatever it is!) of the hydrodynamical behavior observed at RHIC for some years ago should apply also now. When RHIC was in blogs, I constructed a primitive poor man's model for RHIC events and found that I had mentioned stringy structures - among many other things that I would not perhaps mention anymore;-). The introduction of string like objects was natural since in TGD framework even ordinary nuclei are string like objects with nucleons connected by color flux tubes (see this): this predicts a lot of new nuclear physics for which there is some evidence. The basic idea was that in the high density hadronic color flux tubes associated with the colliding nucleon connect to form long highly entangled hadronic strings containing quark gluon plasma. The decay of these structure would explain the strange correlations.
Note: TGD is not string theory although I talk a lot about strings like objects: these objects are three-dimensional and they are an essential element of almost all physics predicted by TGD. Even elementary p"/public_html/articles/ should look string like objects in electro-weak length scales (Kähler magnetic flux tubes with magnetic charges at their ends).
Let us list the main assumptions of the model for the RHIC events and those observed now. Consider first the "macroscopic description".
