High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

Recent developments in heavy quarknoium physics are reviewed in brief, including (i) nonrelativistic QCD(NRQCD), (ii) the importance of color-octet (QQˉ)(Q\bar{Q}) components in the decay and the production of a physical heavy quarkonium state, (iii) limitation of the NRQCD factorization and (iv) the double humps in the ππ\pi\pi spectrum in the decay Υ(3S)Υ(1S)ππ\Upsilon(3S) \to \Upsilon (1S) \pi\pi.
