EXPERIMENTAL REVIEW OF NEW RESULTS ON HADRON SPECTROSCOPY

Abstract

In this talk, I will review the most important progress in the field of hadron spectroscopy in recent one year, especially on multi-quark candidates, including pentaquarks, X(3872), D s (2632) and resonant structures near [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and ωJ/ψ mass thresholds. I will also review the new results on scalar mesons, including σ, κ, f 0(980), f 0(1370), f 0(1500) and possible f 0(1790). This talk will also cover some other interesting results from BES and CLEO-c experiments.
