Force on proton vortices in superfluid and superconducting matter of neutron
stars is calculated at vanishing stellar temperature. Both longitudinal
(dissipative) and transverse (Lorentz-type) components of the force are derived
in a coherent way and compared in detail with the corresponding expressions
available in the literature. This allows us to resolve a controversy about the
form of the Lorentz-type force component acting on proton vortices. The
calculated force is a key ingredient in magnetohydrodynamics of superconducting
neutron stars and is important for modeling the evolution of stellar magnetic
field.
