Weak-decay searches for $$Qs{\bar{u}}{\bar{d}}$$ Q s u ¯ d ¯ tetraquarks
Abstract We propose to search for the open heavy-flavor exotic states with the quark components of $$Qs{\bar{u}}{\bar{d}}$$ Q s u ¯ d ¯ with $$Q=b,c$$ Q = b , c via their weak decays. If there exist such exotic states below the BK or DK thresholds, they can only decay weakly. The advantages include:...
