Effects ofΔS=−ΔQonCP-Nonconservation Phenomenology inK0Decay

Abstract

Incorporating the present experimental value of the $\Delta S=-\Delta Q$ amplitude into the $K^0$ $\mathrm{CP}$-nonconservation phenomenology, we find that solution II (${\eta }_{00}$ and ${\eta }_{+-}$ in opposite quadrants) is as viable as solution I ${\eta }_{00}$ and ${\eta }_{+-}$ in the same quadrant), though both have poor fits. Thus, if a $\Delta S=-\Delta Q$ amplitude is allowed, a clear choice between these two solutions cannot yet be made.
