Space- and timelike electromagnetic kaon form factors

A simultaneous investigation of the space- and timelike electromagnetic form factors of the charged kaon is presented within the framework of light-cone QCD, with perturbative k T factorization including Sudakov suppression. The effects of power suppressed subleading 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 J/Ψ decays.
