1-Consider the pp chain occurring in our sun (see the ?gures in Chapter 11 of the Grif?ths text): a. List all of the solar processes that produce neutrinos, and indicate in each case which ?avor of neutrino is produced b. Estimate the range of neutrino energy for each c. Estimate the peak neutrino ?ux for each 2. Consider some ?ctitious planet “Zearth” in a faraway galaxy. The neutrino scientists are looking to detect neutrinos from their sun with a large tank containing 1040 atoms of the target element they have dubbed “Berserkonium”. Their detector will measure each of the three neutrino ?avors with an effective total cross section for the detection process (as predicted by their esteemed theorist Prof. Spock) to be . If thes=1×10_42cm2 total neutrino ?ux at their detector were to turn out to be:1×1013 cm2s_1 a. How many neutrino events can they expect to detect in their tank of Berserkonium in a length of time equal to one of our earth years? b. What is the detection rate in units of the “SNU”, as was de?ned in class this week? (if you missed the class, you will have to look up the de?nition of the Solar Neutrino Unit). c. How would neutrino oscillations affect their results?
