Integrated ConceptsThe primary decay mode for the negative pion is π-→μ-+ v-μ . (a) What is the energy release in MeV in this decay? (b) Using conservation of momentum,how much energy does each of the decay products receive, given the π- is at rest when it decays? You may assume the muon antineutrino is massless and has momentum p= E/C , just like a photon.

- When L is expressed in km, E, in Gev and Am in eV, the two-flavour mixing formula for the probability of a v, neutrino appearing a distance L later as a v, neutrino is: P(v - v.) = sin (20) sin (1.27 Amlev) Likm] E, IGEV Here, 0 is the neutrino mixing angle, Am is the difference in the squared masses of the neutrino eigenstates and E, is the neutrino energy. The terms in square brackets denote the parameters' units. A long baseline experiment is designed to detect muon-neutrinos with the parameters E, sin 0= 1/2. The distance L between the muon-neutrino source and the muon-neutrino detector can be placed anywhere in the range = 1.1 GeV, Am =2.5 x 10 eV and between 200 km and 1400 km. What is the optimal distance L in km where the muon-neutrino detector should be built? Enter your answer in the box below rounded to the nearest km (e.g. 1234.4 km should be entered as 1234).
