Oscar Cata: 2-forms in holographic QCD

2-forms in holographic QCD 

Oscar Cata, INFN Frascati

The gauge-string duality states that, given a 5-dimensional AdS space, its on-shell fields are the sources of a gauge theory living on a 4-dimensional slice of it. The action on the AdS space comes from d=10 supergravity through compactification and it contains, in particular, 2-form fields. In this talk I will show how to use the holographic prescription to study the impact of 2-form fields on the gauge theory (QCD) side, covering both formal and phenomenological aspects.
