Since 2008 researchers at Belle in Japan found hints of a four-quark particle. Those hints were confirmed.
"This reinforces the 5.1σ (4.7σ) rejection of the 2+ (2− ) hypotheses previously reported by the Belle collaboration, and confirms the 3.4σ (3.7σ) indications from Belle that 1+ is favored over 0− (1− )."
