Abstract: | The isospin violating processes Ψ'→Ψ(11P1)+π° and T"→T(11P1)+π° are investigated in the framework of the multipole expansion in quantum chromodynamics. Using the rate of Ψ'→Ψ+π° as an input to determine the isospin violating vertex, we obtain the following branching ratios for the processes BR(Ψ'→Ψ(11P1)+π°)~10-6-10-5, BR(T"→T(11P1)+π°)~10-5-10-3 for M11p1=1/9(5M13p2+3M13p1+M13p0). These are too small to be detected in the present experiments. |
