Fusion PPI

    How would i go about working out the percentage of energy carried away by neutrinos in a PPI chain?

    Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    So, out of PPI, you'll find that the neutrinos will have a spectrum of energies, since their production is a three body reaction. You'll just need to do some pretty standard kinematics to find out what that spectrum should be - you know the masses of the entrance and exit channel, and you can find a range of appropriate kinetic energies for the entrance channel. The rest is energy/momentum conservation.

    You can compare your results to Fig. 2 of Bahchall, Serenelli, Basu (2005), which shows the solar neutrino energy spectrum for a pretty good solar model. Calculating the fluxes of those neutrinos is another few orders of magnitude in difficulty. ;)
