Description

The Bethe-Salpeter equation is the powerfull method to investigate
bounds states in QCD. Usually this equation is written in momentum space.
In this report we rewrite Bethe-Solpiter in coordinate space. In 4-dimension Eucledian
space equation describing bound state for a system of 2 scalar particles interacting via
exchange of massive scalar particle has a form of 4-order differential equation.
Comparision to another approaches and advantage of proposed method are discussed.
