Homework Statement
A D0 meson (with a rest mass of 1.86 GeV/c2), initially at rest, decays into a K0 meson (with a rest mass of .51 GeV/c2) and a [itex]\pi[/itex]0 meson (with a rest mass of .12 GeV/c2). What is the Kinetic Energy of the [itex]\pi[/itex]0 meson?
Homework Equations
E=[itex]\gamma[/itex]m0c2
p=[itex]\gamma[/itex]m0v
The Attempt at a Solution
Subtracting final rest energy from intial energy its easy to see that the KE(K0+[itex]\pi[/itex]0)=1.23 GeV
Also: [itex]\gamma[/itex]K0mK0c2+[itex]\gamma[/itex][itex]\pi[/itex]0m[itex]\pi[/itex]0c2 = 1.86 GeV/c^2 (The total energy of the two Mesons must equal the first meson)
Without going through all the horrible steps me and my friend did, eventually we got a equation that solved: VK0=f(V[itex]\pi[/itex]0) (I don't have the final equation we got on me)
When then plugged that back into: [itex]\gamma[/itex]K0mK0c2+[itex]\gamma[/itex][itex]\pi[/itex]0m[itex]\pi[/itex]0c2 = 1.86 GeV/c^2
Now at this point we had a solvable equation, the only variable was V[itex]\pi[/itex]0, but it was a hellish equation. After about 20 minutes working on trying to solve it we ran out of time and had to give up- the algebra was just to hard.
Had we had enough time, I'm completely confident we could have solved it, as it was simply a matter of foiling again and again (I think we needed to do it three levels down).
My question is: Is there a way of solving this problem without having to go in and solve for one of the variables in terms of the other, or doing that in a simpler equation?
Thank you, especially if you made it through this.
