The method of unitary clothing transformations in quantum field theory and its applications in nuclear physics

The method of unitary clothing transformations (UCTs) put forward in relativistic quantum field theory (QFT) by Greenberg and Schweber and developed by Shirokov is applied to construct a new family of interactions in meson-nucleon systems. We are stressing that the clothing transformations in question do not alter the original total Hamiltonian, but provides a conceptually more transparent representation of the same Hamiltonian in terms of a new set of operators for particles with physical properties and the relativistic interactions between these 'clothed' particles.
