[edit] What Happens After Particle Decay?
What happens after an elementary particle decays? Is it just gone?
[edit] Quarks final state may not always be up or down.
My comment will be specifically concerning the sentence:
This process continues until stable particles (electrons, or up and down quarks) are produced.
which might mislead some readers into thinking that up and down quarks are the final stable state for quarks. However this is not necessarily the case theoretically. See: [[1]]. I suggest this can be rectified by inserting the word usually before "electrons, or up ..." to account for such exceptions.

[edit] Missing symmetry factor?
In the formula for the decay rate (I think equivalent to what is called 'decay width' in particle phyisics) there should be a symmetry factor of 1/k! for every k identical particles in the final state. —Preceding unsigned comment added by 131.174.17.101 (talk) 12:04, 11 January 2008 (UTC)
