Abstract

We propose a simple parameterization for $q_T$-spectrum of inclusive $Z$-boson production, and test it against world collider data at different energies. The fit gives good agreement with the data, and indicates the existence of two distinguishable breaks in the $q_T$-spectrum. Energy dependences of the fitted parameters are discussed.
