A tetraquark or not a tetraquark? A holography inspired stringy hadron (HISH) perspective
We suggest to use the state Y(4630), which decays predominantly to ΛcΛ‾c, as a window to the landscape of tetraquarks. We propose a simple criterion to decide whether a state is a stringy exotic hadron – a tetraquark – or a “molecule”. If it is the former it should be on a (modified) Regge trajector...
