Confinement in 2-dimensional field model due to scalar instantons.
Roman Shulyakovsky

2-dimensional scalar field theory with Sin-Gordon potential is considered in the case of finite space region. It is shown, that confinement of external fermions is realized in the model due to instantons (tunneling transitions between classically degenerated vacua).
Key words: tunneling, instantons, confinement, 2-dimensional scalar field model
