    Making use of a convolution structure, we introduce a new class of analytic functions mathbbTgp(lambda,alpha,beta,)mathbb{T}^{p}_{g}(lambda,alpha, beta, ) defined in the open unit disc and investigate its various characteristics. Further we obtained distortion bounds, extreme points and radii of close-to-convexity, starlikeness and convexity for functions belonging to the class $mathbb{T}^{p}_{g}(lambda,alpha, beta).
