In this paper‎, ‎we introduce a new class$T_{k}^{s,a}[A,B,\alpha‎ ,‎\beta ]$ of analytic functions by using a‎
‎newly defined convolution operator‎. ‎This class contains many known classes of‎
‎analytic and univalent functions as special cases‎. ‎We derived some‎
‎interesting results including inclusion relationships‎, ‎a radius problem and‎
‎sharp coefficient bound for this class‎.
