This international meeting on ultrahigh energy multiparticle phenomena started with a summary of neutrino physics, followed by a detailed review of LEP results. It moved on to the fast-breaking field of rapidity gaps, hard pomeron and small-x structure functions at both Hera and the FermiLab Tevatron. The major collider experiments at FermiLab, and in particular, the results of the top quark search were presented in complete detail. The fields of intermittency, multiplicities, correlation functions, heavy quarks, soft and semihard hadronic physics, and the particle physics aspects of cosmic rays were subjects of spirited debate.

We present the first evidence for B semileptonic decays into the charmed baryon [Lambda]{sub c} based on 420 fb−1 of data collected at the [Upsilon](4S) resonance with the BABAR detector at the PEP-II ee− storage rings. Events are tagged by fully reconstructing one of the B mesons in a hadronic decay mode. We measure the relative branching fraction [Beta]({bar B} 2![Lambda]{sub c}+ Xl−{bar {nu}}{sub {ell}})/[Beta]({bar B} 2![Lambda]{sub c}+/{bar {Lambda}}{sub c}−X) = (3.2 ± 0.9{sub stat.} ± 0.9{sub syst.})%. The significance of the signal including the systematic uncertainty is 4.9 standard deviations.
