Comprehensive treatment of electromagnetic interactions and three-body spectator equations
Original language description
We present a general derivation of the three-body spectator (Gross) equations and of the corresponding electromagnetic currents. As in a previous paper on two-body systems, the wave equations and currents are derived from those for the Bethe-Salpeter equation with the help of an algebraic method using a concise matrix notation. The three-body interactions and currents introduced by the transition to the spectator approach are isolated and the matrix elements of the e.m. current are presented in detail for a system of three indistinguishable particles, namely, for elastic scattering and for two- and three-body breakup. The general expressions are reduced to the one-boson-exchange approximation to make contact with previous work. The method is general inthat it does not rely on introduction of the electromagnetic interaction with the help of the minimal replacement. It would therefore work also for other external fields.

Obecné odvození tříčásticových rovnic a elektromagnetické interakce v kvazipotenciálním spektátorovém formalismu
Czech description
Obecné odvození kvazipotenciálních Grossových rovnic pro tříčásticové systémy a příslušných elektromagnetických proudů. Jako v předchozí práci o dvoučásticových systémech jsou vlnové rovnice a proudy odvozeny z Bethe-Salpeterovy rovnice pomocí algebraické metody a úsporné maticové notace. Použitá metoda je obecná v tom smyslu, že se neopírá o zavedení elektromagnetické interakce pomocí minimální substituce.
