Radiative transitions between charmonium states offer an insight into the internal structure of heavy quark bound states within QCD. In this work, we performed a systematically investigation of the radiative transitions of $$\psi (nS) \rightarrow \gamma \chi _{cJ}(mP)$$ ψ(nS)→γχcJ(mP) and $$\psi (nD) \rightarrow \gamma \chi _{cJ}(mP)$$ ψ(nD)→γχcJ(mP) via intermediate charmed meson loop with a non-relativistic...
Watermark is a new effective digital copyright protection method and data security technology. A new scheme of image retrieval based upon digital watermarking has been proposed. First, embeds the binary watermark information in carried image, computes the value of NC (normalized correlation coefficient) between query watermark and extracted watermark,and gains the retrieval results. The watermarking...
