Heavy quarkonium ($$\Upsilon$$) production at low transverse momentum ($$P_\perp$$) 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 $$b\bar b$$ production by employing Collins-Soper-Sterman (CSS) formalism. We show that the CSS formalism provides a nice description of $$\Upsilon$$ production data in p+$$\rm\bar{p}$$ collisions at Tevatron and p+p collisions at the LHC.
