Abstract: AbstractIn this paper, we discuss the coherence of the reduced state in system HA ⊗HB under taking different quantum operations acting on subsystem HB. Firstly, we show that for a pure bipartite state, the coherence… read more here.

Abstract: We study the three-body radiative decays $B\to \phi(\rho) K\gamma$ induced by a flavor-changing neutral current in the perturbative QCD approach. Pseudoscalar-vector ($PV$) distribution amplitudes (DAs) are introduced for the final-state $\phi K$ ($\rho K$) pair… read more here.
