The Tachyon Chern-Simons action with a generic tachyon field, and baryons in V-QCD
Jean-Loup Raymond, Matti Järvinen, Elias Kiritsis +2
Consistency with global flavor anomalies requires the presence of Chern-Simons terms in holographic models of QCD. Such terms are analyzed in a setup arising in the holographic V-Q…

Thomas Apostolidis, Matti Järvinen, Elias Kiritsis +3
Flavor-current correlators are studied in strongly-coupled dense (holographic) matter, at finite quark chemical potential and finite isospin asymmetry. The non-Abelian hydrod…

The mixing of graviphotons and dark brane photons to the Standard Model hypercharge is analyzed in full generality, in weakly-coupled string theory. Both the direct mixing as well…
