Fast computation of observed cross section for ψ′ → PP decays
Fast computation of observed cross section for ψ′ → PP decays
Abstract
It has been conjectured that the relative phase between strong and electromagnetic amplitudes is universally -90° in charmonium decays. ψ′ decaying into a pseudoscalar pair provides a possibility to test this conjecture. However, the experimentally observ
