Abstract
A simultaneous investigation of the space- and time-like electromagnetic form factors of the charged kaon is presented within the framework of light-cone QCD, with perturbative -factorization including Sudakov suppression. The effects of power suppressed sub-leading twists and the genuine ``soft'' QCD corrections turn out to be dominant at low- and moderate-energies/momentum transfers . Our predictions agree well with the available moderate-energy experimental data, including the recent results from the CLEO measurements and certain estimates based on the phenomenological analyses of decays.
