We investigate generic n-point correlation functions of conformal field theories (CFTs),with ■ and ■ deformations,in terms of the perturbative CFT approach.We systematically obtain the first order correction to the generic correlation functions of CFTs with ■ or ■ deformation.We compute the out of time ordered correlation OTOC) in the Ising model with ■ or ■ deformation,which confirms that these deformations do not change the integrable property up to the first order level.
