Title:Scalar Glueball in a Top-Down Holographic Approach to QCD

Abstract:Identification of glueballs -- bound states of gauge bosons in Quantum Chromodynamics (QCD) -- is a very important open question in dynamics of the strong interaction. The search for the glueball ground state, carrying scalar quantum numbers, poses a particular challenge due to the existence of (i) several candidates for its realisation in the physical spectrum and (ii) inevitable mixing of the pure glueball state with those comprised of quarks. In this article, I discuss implications of an approach in holographic QCD where, among others, the mass and the two-pion decay of the pure scalar glueball can be studied.
