Survival of Near-Critical Branching Brownian Motion

Consider a system of particles performing branching Brownian motion with negative drift, and killed upon hitting zero. Initially there is one particle at x > 0. Kesten (Stoch. Process. Appl. 7:9-47, 1978) showed that the process survives with positive probability if and only if ε > 0....
