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− )." Belle collaboration, K. Chilikin et al., Experimental constraints on the spin and parity of the Z(4430)+ , Phys. Rev. D88 (2013) 074026, arXiv:1306.4894. "The cost [...] has been evaluated, taking into account realistic labor prices in different countries. The total cost is X (with a…
