Fig. 4From: A GPU based multidimensional amplitude analysis to search for tetraquark candidatesProjections of the other three variables: (from top to bottom) \(m_{J/\psi \pi }\), \(\cos \theta _{J/\psi }\), and \(\varphi\) of the 4D dataset generated according to an ideal signal model (black points with error bars). The fit result (red points with error bars) is superimposed along with the individual fit components corresponding to different \(K^{*}\)sBack to article page
