Generalization of the Lunin-Maldacena transformation on the AdS{sub 5}xS{sup 5} background

In this paper we consider a simple generalization of the method of Lunin and Maldacena for generating new string backgrounds based on TsT transformations. We study multishift Ts{center_dot}{center_dot}{center_dot}sT transformations applied to backgrounds with at least two U(1) isometries. We prove that the string currents in any two backgrounds related by Ts{center_dot}{center_dot}{center_dot}sT transformations are equal. Applying this procedure to the AdS{sub 5}xS{sup 5}, we find a new background and study some properties of the semiclassical strings.
