Abstract:
We investigate a model of a vector massive spinless Bose field in the space $R^3$ interacting with a non-relativistic particle, where the interaction parameter is assumed to be sufficiently small. We study the ground state of the Hamiltonian $H_P$ for a fixed total momentum $P$ of the system and show that such a state is non-degenerate and exists only for a bounded domain of values of this momentum. We also show that, apart from the ground state, the operator $H_P$ has no other eigenvalues below the continuous spectrum. Furthermore, the next two, “one-boson”, branches of the spectrum of $H_P$ are constructed, which describe the scattering of one boson (with two possible polarization values) on the ground state.References
