Exotic $J^{PC}=1^{-+}$ mesons in a holographic model of QCD

Loredana Bellantuono, Pietro Colangelo, Floriana Giannuzzi

Mesons with quantum numbers $J^{PC}=1^{-+}$ cannot be represented as simple quark-antiquark pairs. We explore hybrid configurations in the light meson sector comprising a quark, an…
