In this study we calculate the transverse momentum (pT) distribution of the pseudo-scalar Higgs boson in small pT region. The fixed order results diverge at small values of pT due to the appearance of the large logarithms which are singular as pT -> 0. We resum these logarithms to all orders in perturbation theory up to next-to-next-to leading logarithmic accuracy and match with the fixed order NNLO results to obtain a precise estimate.
