Introduction. Reducing the operating costs of motor fuel for cars is possible through the use of cheaper and at the same time less environmentally harmful alternative energy sources. The main problem with the use of these energy sources, especially f

We investigate a variational approach to the study of two-particle bound states in quantum field theory. The scalar Yukawa model, in which scalar “nucleons” interact via “meson” exchange, is considered. A variational trial state that contains

Some models of relativistic two-particle systems are examined for possible irregularities in the S-wave continuous spectrum. None are found, though we show that with singular effective interaction potentials it is quite easy to run into artificial re

The limit of zero interaction range is correctly defined for a system of three spinless particles and three particles in a doublet state. The scattering amplitude is expanded with respect to the interaction range r, and the corrections of order r ln
