   What is the bottom-up model of AdS/QCD?

   • Bottom-up models A popular bottom-up approachof AdS/QCD is known as the hard-wall model(Erlich-Katz-Son-Stephanov 05). Further refinement to the “soft-wall model” is due to KKSS 06and further to “improved holographic QCD” is due to Gursoy-Kiritsis-Nitti 07, Gursoy-Kiritsis 08, see GKMMN 10.

   How to analyze nonperturbative QCD?

   • To analyze nonperturbative QCD, the lattice QCDMonte Carlo simulation has been also used as a first-principle calculation of the strong interaction. However, it has several weak points. For example, the stateinformation (e.g. the wave function) is severely limited, because lattice QCDis based on the path-integralformalism.

   Can QCD be used to calculate nonperturbative physical quantities?

   • Since [these][these]are highly nonperturbative physical quantities, in principle they are not calculable by the direct use of QCD. Furthermore, although there is available data, this has large errors. These facts cause the huge uncertainties which can be seen in the preceding studies based on the global QCD analysis.

   May 27, 2024 · The Polyakov Loop emerges as a significant tool in studying the phase transitions of QCD, particularly the transition from hadronic matter to a quark-gluon plasma. This transition occurs under extreme conditions, such as those found in the early universe or in heavy ion collisions.
