Abstract

Motivated by the very important discovery of CP violation in charm-decays for the first time, by the LHCb collaboration, the role of nearby resonances such as the scalar f0(1710) in accounting for the observed CP is discussed. It is suggested that the influence of such a resonance may also explain the long-standing puzzle of such a large breaking of SU(3) seen in its decays. It is also explained that intervention of such resonance(s) will render first principles calculations of ΔACP rather difficult. Instead, it is proposed that searches for CP violation in simple radiative final states, such as D0 → γϕ[→ K+ K-], D0 → l+ l- π etc. has much better chance of theoretical precision studies and therefore theoretical and experimental investigations therein are strongly urged.
