I was given this as an extra-curricular activity... way over my understanding of physics, sophmore year undergraduate.
But I can use a bit of help.
I'm given data from a collision resulting in 2 muons.
(this is exactly how the text is written to me, if any of these definitions are not exactly correct please note)
For a muon, we measure
"pt", Transverse momentum = sqrt (px^2 + py^2)
"phi", angle in the x-y plane
"eta", pseudorapidity, which is another form of the angle from the z-axis
"mass", the mass of the muon
I need to find the Lorentz vector.
For the energy I figured out
E = sqrt ( mass^2 + momentum^2) where momentum should be the magnitude of the 3vector momentum.
What I'm having trouble with is finding Pz, momentum in the z axis.
Maybe I'm not quite understanding the definition of pseudorapidity?
I'd find Px and Py by
Px=Pt cos(phi) and Py = Pt sin(phi)
But how do I find the z component of momentum?
psuedorapidity only gives me an angle for the z component correct? and am I correct that Ptransverse doesn't contain any z component?
