We study two- and three-gluon glueballs of $C=+$ using the method QCD sum rules. systematically construct their interpolating currents, find that all spin-1 currents vanish. This suggests ``ground-state'' do not exist within relativistic framework. calculate masses two-gluon with ${J}^{PC}={0}^{\ifmmode\pm\else\textpm\fi{}+}/{2}^{\ifmmode\pm\else\textpm\fi{}+}$ ${J}^{PC}={0}^{\ifmmode\pm\else\t...

For a particle moving on half-line or in an interval the operator $\stackrel{\ifmmode \hat{}\else \^{}\fi{}}{p}=\ensuremath{-}i{\ensuremath{\partial}}_{x}$ is not self-adjoint and thus does qualify as physical momentum. Consequently canonical quantization based \^{}\fi{}}{p}$ fails. Based upon alternative concept for momentum ${\stackrel{\ifmmode \^{}\fi{}}{p}}_{R}$, we show that can indeed be ...

Th e fi nancial regulation architecture in both the United States and China developed during eras when retail deposits and bank loans were the primary mode of fi nancial intermediation. Th e function of banks is to transform short-term deposits into long-term loans, while providing liquidity for depositors. Experience has taught regulators hard lessons that this activity must be subject to prud...

Spin is the only internal degree of freedom of an electron, and that raises two interesting, closely related questions. First, what kind of new physics emerges when the processes traditionally attributed separately to electron charge and electron spin become closely interconnected? And second, to what sort of new electronic devices might this physics lead us? Success in applications has the pot...
