Lightfront spindependent spectral function and nucleon momentum distributions for a threebody system
Poincare covariant definitions for the spindependent spectral function and for the momentum distributions within the lightfront Hamiltonian dynamics are proposed for a threefermion bound system, starting from the lightfront wave function of the system. The adopted approach is based on the Bakamjian–Thomas construction of the Poincaré generators, which allows one to easily import the familiar and wide knowledge on the nuclear interaction into a lightfront framework. The proposed formalism can find useful applications in refined nuclear calculations, such as those needed for evaluating the European Muon Collaboration effect or the semiinclusive deep inelastic cross sections with polarized nuclear targets, since remarkably the lightfront unpolarized momentum distribution by definition fulfills both normalization and momentum sum rules. As a result, also shown is a straightforward generalization of the definition of the lightfront spectral function to an Anucleon system.
