Flavor Exotic Triply-Heavy Tetraquark States in Ads/Qcd Potential

Abstract

We study the S-wavemass spectra of flavor exotic triply-heavy tetraquark states cc (c) over bar(q) over bar, cc (b) over bar(q) over bar, bb (c) over bar(q) over bar and bb (b) over bar(q) over bar. We adopt a diquark-antidiquark scheme to solve Schrodinger equation. The calculations are carried out in a nonrelativistic quark model with a color interaction described by a potential computed in AdS/QCD. The AdS/QCD potentialmodel consists of a central potential which reflects short distance and large distance behaviour of QCD, spin dependent term for hyperfine splitting and a constant term. We find stable state candidates in the cc (c) over bar(q) over bar sector whereas in the cc (b) over bar(q) over bar, bb (c) over bar(q) over bar and bb bq sectors all the states lie above corresponding S-wave meson-meson thresholds.
