Query: A twisted look on kappa-Minkowski: U(1) gauge theory   Kappa-Minkowski space-time is an example of noncommutative space-time with
potentially interesting phenomenological consequences. However, the
construction of field theories on this space, although operationally
well-defined, is plagued with ambiguities. A part of ambiguities can be
resolved by clarifying the geometrical picture of gauge transformations on the
kappa-Minkowski space-time. To this end we use the twist approach to construct
the noncommutative U(1) gauge theory coupled to fermions. However, in this
approach we cannot maintain the kappa-Poincar\'e symmetry; the corresponding
symmetry of the twisted kappa-Minkowski space is the twisted igl(1,3) symmetry.
We construct an action for the gauge and matter fields in a geometric way, as
an integral of a maximal form. We use the Seiberg-Witten map to relate
noncommutative and commutative degrees of freedom and expand the action to
obtain the first order corrections in the deformation parameter.
