The quark-gluon plasma and D6-branes on the conifold

Understand

We investigate the possibility of constructing a supergravity background dual to the quark-gluon plasma using D6-branes wrapping a three-cycle in the deformed conifold.

• The UV-completion of this setup is given by M-theory on a G2 holonomy manifold.
• For the class of metrics considered we find that there are only non-extremal D-brane solutions in the limit of the singular conifold with the singularity being resolved by the D-brane horizon.
• The thermodynamic properties of the system show some puzzling features, such as negative specific heat at an unusual behavior of the entropy.
