In-matter three-body problem
A. N. Kvinikhidze, B. Blankleider
We formulate three-dimensional equations for the finite temperature in-matter three-body problem. Our approach takes into account the full infinite series for the effective pair-in…
Perturbation theory for bound states and resonances where potentials and propagators have arbitrary energy dependence
A. N. Kvinikhidze, B. Blankleider
Standard derivations of ``time-independent perturbation theory'' of quantum mechanics cannot be applied to the general case where potentials are energy dependent or where the inver…
Three-body system in leading order Effective Field Theory without three-body forces
B. Blankleider, J. Gegelia
The use of leading order effective field theory (EFT) to describe neutron-deuteron scattering leads to integral equations that have unusual behaviour: when only two-body interactio…
Complete set of electromagnetic corrections to strongly interacting systems
A. N. Kvinikhidze, B. Blankleider
We show how to obtain a complete set of electromagnetic corrections to a given nonperturbative model of strong interactions based on integral equations. The gauge invariance of the…
Unified model of the relativistic piNN and gamma-piNN systems
B. Blankleider, A. N. Kvinikhidze
We present a unified description of the relativistic piNN and gamma-piNN systems where the strong interactions are described non-perturbatively by four-dimensional integral equatio…
Gauging the three-nucleon system
A. N. Kvinikhidze, B. Blankleider
We show how to attach an external photon to a system of three strongly interacting nucleons described by three-body scattering equations. Our method involves the idea of gauging th…
