The probability of a muon neutrino oscillating to a tau neutrino is given by R+r

Question

The probability of a muon neutrino oscillating to a tau neutrino is given by R+r sin2(26923)sin"(1.267 ? -Ger-), where E is the neutrino E eVkm energy, L is the distance the neutrino has travelled and the mixing angles and mass differences may be taken as sin"(2%) ul , ??12 2.5 x10-3eV2, sin"(2%)-086, Anht 8x 10-5 eV, sin (28,)0. An accelerator produces a beam of neutrinos that have a maximum intensity at E-1 GeV. What distance from the neutrino source would be a good place to position a detector in order to study neutrino oscillation? Explain your answer. If the accelerator produced a beam of electron neutrinos, should the detector be placed at a different position? If so where? Consider 3 particle physics accelerators with the following centre of mass collision energies: LEP: electron-positron collider, Vs-209GeV a. b. Tevatron: proton-antiproton collider, Vs-1.96TeV c. LHC: proton-proton, Vs-8TeV Which of these experiments could produce the following particles: i. W boson ii. Z boson ii. Top quark iv. Higgs boson v. Z' boson with mass 1TeV/c2

Explanation / Answer

a.LEP :The Large Elecrton-Positron Collider

It can produce Z-boson and W-boson .

b. Tevatron : Proton-antiproton collider

It produces Higgs boson, Z' boson with mass 1 Tev/c2

c. LHC : Proton-Proton

It gives Top quark particle.
