One of simplest jet process, 0-jet production, is the Drell-Yan hence most accurate prediction is available. In this talk, I will discuss my recent progress in understanding of transverse momentum dependent observables in this process by using a theory tool called the Soft-Collinear Effective Theory (SCET) that allows us to factorize the cross section and to better control over accuracy of the theory prediction by resumming large logarithm in small pT region. I will discuss fast and accurate method for the resummation, which allows us to analytically express the final cross section in terms of series sum of Hermite polynomials.  M2035 Physics Research Building America/New_York public
