The Saga of $h_c$ and $h_b$ Search in Heavy Quarkonia
arXiv:hep-ph/0408081
Abstract
In this brief review, we examine carefully and critically the status of search for the $h_c$ [$Ï(1^1P_1)$] charmonium state and the $h_b$ [$Î¥(1^1P_1)$] bottonium state, initiated by the E760 experiment. Recent experimental studies at CLEO/BABAR/BELLE are examined in the light of new theoretical and phenomenological understanding.
