Abstract: In this work we compare two different, approaches to calculating the three-body resonances on the basis of Faddeev differential equations. The first one is the complex scaling approach. The second method is based on an immediate calculation of resonances as zeros of the three-body scattering matrix continued to the physical sheet.

Keywords: Three-body systems, complex scaling, resonances
