A New Class of Solutions to the Strong CP Problem with a Small Two-Loop theta
Darwin Chang, Wai-Yee Keung
We present a new class of models which produce zero theta (QCD} angle at the tree and one-loop level due to hermiticity of sub-blocks in the extended quark mass matrices. The struc…

Belle J/psi+eta_c anomaly and a very light scalar boson
Kingman Cheung, Wai-Yee Keung
The large rate of the production observed by the Belle collaboration has posed a serious challenge to our understanding of the quarkonium. We examine a scenario that ther…
