Restricted locality of quark-hadron duality in exclusive meson photoproduction reactions above the resonance region
INT J MOD PHYS A 20:8-9 (2005) 1910-1913
Abstract:
We show how deviations from the dimensional scaling laws for exclusive processes may be related to a breakdown in the locality of quark-hadron duality, i.e. the "restricted locality". For exclusive reactions like meson photo- and electroproduction above the resonance region, we explore the effects arising from such a local duality breaking and propose that it can be a possible source for oscillations about the smooth quark counting rule predicted by pQCD in the 90-degree differential cross sections.Dynamics and decay of heavy-light hadrons - art. no. 094004

Hadron spectroscopy (theory): Diquarks, tetraquarks, pentaquarks and no quarks
(2005) 100-107
Abstract:
States beyond those expected in the simple constituent quark model are now emerging. I focus on the scalar glueball and its mixing with states in the qq nonet, and also on correlations in Strong QCD that may form diquarks and seed qqqq states. Some models of the pentaquark candidate Theta(1540) are critically discussed.Pentaquark implications for exotic mesons - art. no. 014017
