For a critical binary branching Bessel process starting fromx≫1 and stopped atx=1, we prove some conditional limit laws of the number of particles arriving atx=1 before a scaled large time. Five regions of the dimensional index of a Bessel process: −∞<d<2,d=2, 2<d<4,d=4 and 4<d<∞ are showed to have somewhat different behaviors. Our probabilistic results are proved by analyzing differential equations satisfied by generating functions. A salient theme is a comparison principle technique deliberately used to estimate solutions of\(u_t - \left( {D^2 + \frac{{d - 1}}{x}D} \right)u + u^p = 0\) inR+×R+ wherep is greater than 1. The casep=2 corresponds to the process considered.
