Higgs particles interacting via a scalar Dark Matter field
Yajnavalkya Bhattacharya, Jurij W. Darewych
We study a system of two Higgs bound state, interacting via a real scalar Dark Matter mediating field, without imposing symmetry on the DM sector of the postulated Lagrangian…
Relativistic corrections to the Zeeman splitting of hyperfine structure levels in two-fermion bound-state systems
Andrei G. Terekidi, Jurij W. Darewych, Marko Horbatsch
A relativistic theory of the Zeeman splitting of hyperfine levels in two-fermion systems is presented. The approach is based on the variational equation for bound states derived fr…
Hyperfine Structure and Zeeman Splitting in Two-Fermion Bound-State Systems
Andrei G. Terekidi, Jurij W. Darewych, Marko Horbatsch
A relativistic wave equation for bound states of two fermions with arbitrary masses which are exposed to a magnetic field is derived from quantum electrodynamics. The interaction k…
Variational Two Fermion Wave Equations in QED: Muonium Like Systems
Andrei G. Terekidi, Jurij W. Darewych
We consider a reformulation of QED in which covariant Green functions are used to solve for the electromagnetic field in terms of the fermion fields. The resulting modified Hamilto…
A Variational Fock-Space Treatment of Quarkonium
L. Di Leo, J. W. Darewych
The variational method and the Hamiltonian formalism of QCD are used to derive relativistic, momentum space integral equations for a quark-antiquark system with an arbitrary number…
Exact solutions and triviality of lambda (phi^*phi)^2 theory in the Feshbach-Villars formulation
Jurij W. Darewych
The complex scalar quantum field theory with a lambda (phi^*phi)^2 interaction is considered in the Feshbach-Villars formulation. It is shown that exact few-particle eigenstates of…
