Inclusive hadron spectroscopy in J/Psi and Psi(2S) — •Ingo Heller, Wolfgang Kühn, Jens Sören Lange, Yutie Liang, Björn Spruck, and Qiang Wang — II. Physikalisches Institut, Heinrich-Buff-Ring 14, 35390 Gießen

The upgraded BESIII detector at BEPCII in Beijing is a unique and powerful facility for studying physics in the energy range up to 4 GeV. BESIII has collected data from about 220M J/Ψ and 110M Ψ′ events, which is the largest data sample in the world and even 4 times higher than CLEO-c, so it provides the possibility for precision results. It will also provide the potential for discovering phenomena that have been overlooked at previous facilities because of statistical limitations. The focus of this talk will be the inclusive hadron spectroscopy in J/Ψ and Ψ′. Focusing on π, η, η′ and ω production, pT dependences for these light hadrons in e+e-collisions will be presented.
