| Sep 29, 2019 at 15:23 | comment | added | Cosmas Zachos | Yes, the EM decay swamps the strong I-violating one which is meant to be even weaker! | |
| Sep 29, 2019 at 15:21 | comment | added | Cosmas Zachos | 2nd class currents is a separate, long and subtle story. Basically, Weak currents violate C,P, in predictable and precise ways, so G-parity violations are purely due to I violations. You observe such in the decay cited. Caveat: there is lots of nonsense hidden in the literature on this, however.... In my answer, I got you a clean channel. | |
| Sep 29, 2019 at 15:18 | comment | added | avitase | So what you are saying is, that the background $\rho^0 \to 2\pi^0 \gamma$ in $\rho^0 \to 2\pi^0$ is too hard to handle? | |
| Sep 29, 2019 at 15:13 | comment | added | Cosmas Zachos | For the ρ, no way to compete with $\Gamma_{10}, ~~~ 2\pi^0 \gamma$. You are looking in the wrong place. | |

| Sep 29, 2019 at 15:00 | comment | added | avitase | Could you explain what you mean with the $\tau \!\to \eta \pi^0 \nu_\tau$ decay? How does isospin conservation enters here? | |
| Sep 29, 2019 at 14:42 | comment | added | avitase | Sorry for the confusion. There was a typo. I wanted to refer to $\rho^0 \! \to 2\pi^0$ instead of $\eta$. You are right, $\eta \!\to 2\pi^0$ is indeed measured. | |

| Sep 28, 2019 at 11:45 | comment | added | Cosmas Zachos | Tau to eta pi nu is second class. Don’t be stymied by cutting out weak interactions. Weinberg’s book details such. | |
| Sep 28, 2019 at 10:52 | comment | added | avitase | Thanks for your help. I searched the PDG. But I failed to find an upper limit for the $\eta$ decay, as well as branching ratios for the $\Delta$ decays. Could you be a bit more precise and / or point me to a specific PDG page / link? | |
