RT Journal Article T1 Klein–Gordon kinks with fourth order derivative self‐coupling A1 Fernández-Rañada, Antonio AB A Klein–Gordon field with a derivative fourth order self‐coupling is studied. It is shown that the kinks of the model form singlets, doublets, or triplets of electric charge, according to the values of the coupling constants.
