1202.2629 (Fumio Hiroshima et al.)

Enhanced binding of an N-particle system interacting with a scalar field
II.Relativistic version

Fumio Hiroshima, Itaru Sasaki
An enhanced binding of $N$-{\it relativistic} particles coupled to a massless
scalar bose field is investigated. It is not assumed that the system has a
ground state for the zero-coupling. It is shown, however, that there exists a
ground state for sufficiently large coupling. The proof is based on checking
the stability condition and showing a uniform exponential decay of infrared
regularized ground states.
