<div><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">I will present a novel holographic formulation of heavy baryons that has manifest chiral and heavy quark symmetry.</span><br>

<div><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">I will use it to show that heavy baryons and their exotics with explicit and hidden charm and bottom, emerge as bound states of a low-lying heavy meson
multiplet and a flavor instanton in bulk. I will confirm the existence of two low-lying charmed pentaquark states and new ones. I will also show that tetraquark states emerge as holographic molecules, by binding the same heavy meson multiplet to a sphaleron
path instead. Remarkably, this description provides a realisation of a “quark-diquark ” correspondence whereby a doubly heavy tetraquark as a boson is geometrically deformed to a heavy baryon as a fermion. This construction predicts bound tetraquark
states with bottom and charm as Efimov states, a likely first manifestation of the Efimov mechanism in hadronic spectroscopy.</span></div>
