Abstract
The form factors in K ℓ3 decay are discussed in a current algebra approach by writing unsubtracted dispersion relations for the matrix elements of suitable retarded commutators between single particle states and vacuum, at (arbitrary) fixed linear combination of the two momentum transfers. This allows us to include the contributions of all the relevant poles and a consistent solution of the current algebra equations is then possible.
