A new finite N=2 supersymmetrical sigma model with higher derivatives in four dimension

A new finite N=2 supersymmetric sigma model with higher derivatives in four dimensions is formulated. Model function in N=2, d=4 superspace in N=2 terms of chiral mass superfields is pointed out. Lagrangian of considered theory in N=1 superspace and in components is calculated. Using N=2 perturbative superfield theory methods it is proved, that the plotted N=2 model is ultraviolet-finite in all orders of perturbation quantum theory in 4-dimensional space-time
