摘要：
A relation between the mass M-3 of the relativistic three-body bound state and the mass M-2 of the two-body one is obtained for the zero-range interaction (phi(4) theory), using light-front dynamics. It is found that the three-body system exists only when M-2 is greater than a critical value M(c)approximate to1.43m (m is the constituent mass). For M-2 = M-c, the mass M-3 turns into zero and for M-2<M-c, there is no solution with real value of M-3.
