Identified the leading decay modes of the tetraquark.
Demonstrated the potential stability of the double-beauty tetraquark.
Abstract
We briefly review the stability of the -type of tetraquarks with two heavy quarks and two light antiquarks. We present the first comprehensive estimate of the lifetime and leading decay modes of the exotic meson with double beauty.
