Light-cone sum rules study on the purely non-factorizable $\hat{I}{›}_c^{+}\to \hat{I}{ž}^0{K}^{+}$ decay

Yu-Ji Shi, Zhen-Xing Zhao

We investigate the purely non-factorizable $\hat{I}{›}_c^{+}\to \hat{I}{ž}^0{K}^{+}$ decay using light-cone sum rules. To extract the decay amplitudes, a three-point correlation function is defin…
