Abstract

We study the S-wave mass spectra of flavor exotic triply-heavy tetraquark states $c c \bar{c} \bar{q}$ $cc\bar{c}\bar{q}$ , $c c \bar{b} \bar{q}$ $cc\bar{b}\bar{q}$ , $b b \bar{c} \bar{q}$ $bb\bar{c}\bar{q}$ and $b b \bar{b} \bar{q}$ $bb\bar{b}\bar{q}$ . We adopt a diquark–antidiquark scheme to solve Schrödinger 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 potential model 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 $c c \bar{c} \bar{q}$ $cc\bar{c}\bar{q}$ sector whereas in the $c c \bar{b} \bar{q}$ $cc\bar{b}\bar{q}$ , $b b \bar{c} \bar{q}$ $bb\bar{c}\bar{q}$ and $b b \bar{b} \bar{q}$ $bb\bar{b}\bar{q}$ sectors all the states lie above corresponding S-wave meson-meson thresholds.
