Anisotropic string tensions and inversely magnetic catalyzed deconfinement from a dynamical AdS/QCD model

Understand

We extend previous work on dynamical AdS/QCD models by introducing an extra ingredient under the form of a background magnetic field, this to gain insight into the influence such field can have on crucial QCD observables.

• Therefore, we construct a closed form analytic solution to an Einstein-Maxwell-dilaton system with a magnetic field.
• We specifically focus on the deconfinement transition, reporting inverse magnetic catalysis, and on the string tension, reporting a weaker/stronger confinement along/perpendicular to the magnetic field.
• The latter, being of importance to potential modelling of heavy quarkonia, is in qualitative agreement with lattice findings.
