# 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 superstring theory, e.g. by validating particle spectra of MSSM, so, my question is about effects that more directly hints to the strings or branes themselves and some peculiar nature they have?

• Is there a reason you asked about heavy ion collisions and not other high-energy experiments? – Mitchell Porter May 18 '19 at 6:31
• Yes, of course, I have reason. AFAK, LHC ion collisions are the only experiment, where humans actively control the processes and not just observe the effects of naturally occurring phenomena. My hope is that I (we) can discover computing-beyond-quantum-computing, sub-femtoscale computing, computing with quarks and gluons and something like that. And such computing may be implemented by dusty quark-gluon plasmas. Well, all that is in inception, but we should move strive, because quantum computing is quite bounding. – TomR May 18 '19 at 11:30
• Your premise is not correct, ion collisions are even "messier" than proton-proton collisions. On the other hand, electron-positron colliders are "cleaner" because the collision energy can be controlled precisely. However, there are many other kinds of particle experiments currently going on where the processes are highly controlled. – Helen May 27 '19 at 22:54
