Description

We investigate the H-dibaryon (uuddss) in holographic QCD [1, 2].
Holographic QCD is derived from a QCD-equivalent D-brane system
in the superstring theory via the gauge/gravity correspondence.
In holographic QCD, all baryons appear as topological chiral solitons
of Nambu-Goldstone bosons and (axial) vector mesons [1, 2].
In this framework, the H-dibaryon can be described as an SO(3)-type
hedgehog state [3]. In this paper, we present the formalism of
the H-dibaryon in holographic QCD, and investigate its properties.

Summary

We investigate the H-dibaryon (uuddss) in holographic QCD, which is derived from a QCD-equivalent D-brane system via the gauge/gravity correspondence.
