We study the S-wave mass spectra of flavor exotic triply-heavy tetraquark states c c c ¯ q ¯ , c c b ¯ q ¯ , b b c ¯ q ¯ and b b b ¯ 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 c ¯ q ¯ sector whereas in the c c b ¯ q ¯ , b b c ¯ q ¯ and b b b ¯ q ¯ sectors all the states lie above corresponding S-wave meson-meson thresholds.
