Study of hadronic ϒ(nS) decays in (multi-)baryons

A critical overview of the available experimental data on fragmentation and hadronization processes in e+e− annihilations, in the energy region of the first narrow Υ resonances, is presented. The possibility of producing deuterons in the inclusive decay of Υ(nS) (n = 1,2,3) emerged from the data. A second interesting observation is the enhanced baryon production in the Υ decays as compared to continuum. These issues suggest to pursue further searches for multi-baryonic states, possibly with strangeness, in the data collected by the most recent experiments operating at B-factories. Ideas for possible analyses are put forward.
