Problems at the interface between heavy flavor physics, QCD and hadron spectroscopy

Abstract

• Pentaquark. Why it is important and how new technologies (vertex detectors) suggest drastically different approaches from the search used by Ashery et al. • Problems in B decays with implications for heavy quark decays to excited light quark states like the al. • Problems in B and D decays to final states including η and η′ indicating that standard quark mixing might not hold. • Possible contributions of hybrid quarkonium states to B decays. • Heavy flavor decays to ωπ which disagree with conventional expectations. • Possible new spin effects in Λb decay and the effect on the lifetime difference between the Λb and B mesons.
