Signal Enhancement Background Suppression
2010/3/10
We describe a two-photon absorption process that is excited by entangled pairs but not non-entangled pairs with the same energy and polarization. Photon states can be selected so that in the non-entan...
Observation of a ppb mass threshoud enhancement in \psi^\prime\to\pi^+\pi^-J/\psi(J/\psi\to\gamma p\bar{p}) decay

The decay channel $\psi^\prime\to\pi^+\pi^-J/\psi(J/\psi\to\gamma p\bar{p})$ is studied using a sample of $1.06\times 10^8$ $\psi^\prime$ events collected by the BESIII experiment at BEPCII. A strong ...
