Heavy quarkonium (Υ) production at low transverse momentum (P⊥) in high-energy hadronic collisions is revisited from the point of view of transverse momentum dependent (TMD) framework. We perform resummation of double logarithmic correction associated with initial-state soft gluon shower for bˉb production by employing Collins-Soper-Sterman (CSS) formalism. We show that the CSS formalism provides a nice description of Υ production data in p+ˉp collisions at Tevatron and p+p collisions at the LHC.
