Will this approach generate any interest?

Oh yes it does
They have actually gathered quite some results already if you look at their publications, and by now other people, who were first pointing to inconsistencies in the model, are beginning to advertise there own versions

It seems that everyone wants to go down in history as the inventor of a NEW expression.
By doing a search of “light-front framework”. I found a lot of papers.
Yuk! … I know so little.
Can you give a laymans explanation.

By doing a search of “light-front framework”. I found a lot of papers.

The "light front" is not so important in that case. The relevance of this work is the AdS/QCD part.

edit
Let me make it clear : what is new from the point of view of the authors is the "light front", but the essential of this thing, on which they are working for several years now, nad which is sexy and trendy and needs to be understood first is the AdS/QCD

I just found this "Introduction to AdS/QCD and Light-Front Hadron Dynamics" at http://www.slac.stanford.edu/grp/th/recentlectures.html

I'll give it my best try.

I'll give it my best try.

Frankly, Stan is not known for the easiness of his litterature. Usually people enjoy attending his talks because he is able to present more than 2 slides per minutes. Heavy slides...

Thanks for your comments and help.
Yes, the slides sent me on a search. heheh

Once again, “If I thought of it someone else has thought of it before me.” is proving to be right.

I don't expect the "pros" to be interested in my learning curve so I will be making my progress/links in my blog.
Thanks again

Thank you, for reporting the relevant link you progress with. It is very useful for reference.

We need to have a good guidance from the lattice calculations with regard to the
location of the critical point. The exact location of the critical point is not known yet.

Moreover, using the zero temperature potential and without adding any extra parameter, we obtain a value for the the critical temperature in very good agreement with the one computed from the lattice.

I have no idea if the claim of Holographic QCD is valid.
Could someone comment.
