Heavy ion collision book
I would like for some recommendations for books that focuses mainly on heavy ion collisions.
I already read modern particle physics by Mark Thomson but didn't find there anything about that subject.

What’s the basic procedure to draw a QCD phase diagram?
Could someone recommend a book/resource where I can find a detailed way of sketching out a QCD temperature-chemical potential phase diagram using gap equations (eg. equations 35-37 or 39-40 as given ...

How is the nucleus-nucleus CM energy per nucleon related the proton-proton CM energy in a circular accelerator?
If I understand it correctly, the center of mass energy per nucleon pair in heavy ion collisions is given by $$\sqrt{s_{NN}}=\sqrt{(p_a/A_a+p_b/A_b)^2},$$ where $a$ and $b$ label each colliding nuclei,...

Invariance of Particle Distribution in Heavy Ion Colissions
I'm reading about about Heavy Ion collisions from the book by Csernai and i can't make sense of the proof that the particle distribution $f(x,p)$ is an invariant scalar. Before i quote the book:
The ...

Difference between particle rapidity and space-time rapidity
I have seen a lot of posts asking about the difference between the rapidity $y$ and the pseudorapidity $\eta$, and I understand it well enough (at least in the context of heavy-ion collisions). They'...

Quark gluon plasma at arbitrarily high temperature
Does the quark-gluon plasma become weakly coupled at infinite temperature (due to asymptotic freedom), or does it maintain some non-perturbative behavior?

What superstring or brane phenomenology can be observed in LHC heavy ion collisions?
What superstring or brane phenomenology can be observed in heavy ion collisions at the LHC energy densities. Of course, I am aware that LHC experiments can constrain the conclusions from the ...

What is the "jet trigger" in heavy-ion collisions?
I saw the word "trigger" many times in papers. And never true understand it. It seems like to set an threshold when select jet? So I want to understand more clearly. Thanks for your help.
Here is an ...

What is the "smearing" in heavy-ion collisions?
I often saw the word "smearing" in some papers. I don't know what it means. This word doesn't have an appropriate interpretation which is related to physics in chinese. So I feel hard to get the key ...

Highest man-made temperature: why only 470 MeV?
In 2012, the ALICE experiment at CERN achieved a temperature of 5.5 trillion kelvin (5.5 × 1012 K). This was regarded as the highest man-made temperature.
However, even this temperature seems ...
