\(t\) variable. Relevant elastic collision for the t and u Mandelstam variables. The relevant collision for the \(t\) variable is shown in the diagram. The momenta of particles 1 and 2 are equal and oppsite. Since they have the same mass, they must have the same energy too.Mandelstam variables 1 positive 2 negative. Edit 2: I've calculated these for the nonelastic proces ee (since inelastic problems are the source of the problem) and I found that: s2m(mEB), tm2M22mEC, um2M22mED, where m is the mass of the electron and M mandelstam variables problems

The Mandelstam variables are useful Lorentz invariants: t (PaPc) u (PaPo) (a) Show that s t u mHng m m2, . [ 10 points (b) Show that the total center of mass energy is given by s. [10 points (c) The LHC collides protons in the lab frame with an energy of 6. 5 TeV against other protons with an energy of 6. 5 TeV (so that 's
