What quantum particle does Z zero decay into? Is the decay predictable?

Z0 decay to 4 possible particles, electron-positron pair, muon-antimuon pair; tau-antitau pair and quark-antiquark pair. The quark-antiquark pair happens (1/0.048) more often than the other 3 - all of which happen at the same probability - so yes you can predict that if a Z0 particle is struck by an electron positron pair, the likely particles produced will be... You asked some questions on another question: Am I a particle physicist - No - but your question seemed loaded and you can verify all my statements with some studying of your own - I studied and continue to study quantum mechanics - for fun and practice :) I have added a link to a great article that covers mass and points you in the right direction about Photon / ggs Interactions - but is just a very interesting read in general.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
