On Bulk Viscosity at Weak and Strong 't Hooft Couplings
Alina Czajka, Keshav Dasgupta, Charles Gale +4
Bulk viscosity is an important transport coefficient that exists in the hydrodynamical limit only when the underlying theory is non-conformal. One example being thermal QCD with la…
Bulk Viscosity at Extreme Limits: From Kinetic Theory to Strings
Alina Czajka, Keshav Dasgupta, Charles Gale +4
In this paper we study bulk viscosity in a thermal QCD model with large number of colors at two extreme limits: the very weak and the very strong 't Hooft couplings. The weak coupl…
Renormalization Group Flow, Stability, and Bulk Viscosity in a Large N Thermal QCD Model
Keshav Dasgupta, Maxim Emelin, Charles Gale +1
The ultraviolet completion of a large N QCD model requires introducing new degrees of freedom at certain scale so that the UV behavior may become asymptotically conformal with no L…
Infrared Dynamics of a Large N QCD Model, the Massless String Sector and Mesonic Spectra
Keshav Dasgupta, Charles Gale, Mohammed Mia +2
A consistency check for any UV complete model for large N QCD should be, among other things, the existence of a well-defined vector and scalar mesonic spectra. In this paper, we us…
Vector Meson Spectrum from top-down Holographic QCD
Keshav Dasgupta, Charles Gale, Mohammed Mia +2
We elaborate on the brane configuration that gives rise to a QCD-like gauge theory that confines at low energies and becomes scale invariant at the highest energies. In the limit w…
