Variational Worldline Approximation for the Relativistic Two-Body Bound State in a Scalar Model
K. Barro-Bergflödt, R. Rosenfelder, M. Stingl
We use the worldline representation of field theory together with a variational approximation to determine the lowest bound state in the scalar Wick-Cutkosky model where two equal-…

Worldline Variational Approximation: A New Approach to the Relativistic Binding Problem
K. Barro-Bergflödt, R. Rosenfelder, M. Stingl
We determine the lowest bound-state pole of the density-density correlator in the scalar Wick-Cutkosky model where two equal-mass constituents interact via the exchange of mesons.…
