Description of the X(5568) and proposed 750 GeV/c² state in terms of a first-order tetraquark mass formula.

A recently discovered tetraquark candidate having four distinct flavors is investigated using a first-order mass formula. This mass relationship is based on weakly bound meson clusters and provides a reasonable prediction for the measured X(5568) tetraquark mass. The possible discovery of a 750 GeV/c² state is also represented reasonably well by the first-order tetraquark mass formula incorporating a tttt structure. [ABSTRACT FROM AUTHOR]
