Thank you! However, we haven't studied G-parity yet, and our teacher wants us to solve the problem using isospin and boson statistics.

I started combining 2 pions: ##|\pi ^{0},\pi ^{0} >=\sqrt{\frac{2}{3}}|2,0>-\sqrt{\frac{1}{3}}|0,0>## What should i do now? Should i continue combining the third pion or can i already say that it's forbidden? If yes, why? Is it because the state antisymmetric, impossible for two bosons?

Yes. I wanted to find the most general transformations for energy and momentum of particles between the two reference frames. The energies and momenta are referred to a particle in a specific reference frame. I tried to solve some exercises and i got confused a little with signs. Then, solving...

I'm using these equations to solve problems about collisions in particle physics: switching from the laboratory frame to the center of mass frame and viceversa.

Thank you, what a stupid error. I was so confused. Can you please confirm that, given a particle energy and momentum in the center of mass frame, the transformations to find the same quantities in the lab frame are (in natural units): ##E_{lab}=\gamma _{cm}E_{cm}+\beta _{cm}\gamma...

I tried to use the Lorentz transformation: ##E^{*}_{\gamma }=\gamma _{cm}E_{\gamma }-\beta _{cm}\gamma _{cm}p_{\gamma }## We have a photon, so it becomes: ##E^{*}_{\gamma }=\gamma _{cm}E_{\gamma }(\beta _{cm}-1)## Unfortunately, the solutions say that the correct way is to use the inverse...

In the center of mass frame of reference i found that ##p^{*}=\frac{[(M^{2}-m_{\nu}^{2}-m_{K}^{2})^{2}-4m_{\nu}^{2}m_{K}^{2})]^{1/2}}{2M}##. I don't know how to find the momentum distribution ##p_{L}(\theta)## considering that i have 2 different mesons with a specific number ratio...

Hello everybody :) I'm Lucy and I'm from NY. Now I'm in Berlin to study physics. I'm interested in environmental physics, violin and base jumping, i hope to learn a lot in this forum. See you soon! Lucy.
