Neutrino Production by Sun: Heep's Intensity & Branching Ratios

Click For Summary
SUMMARY

The forum discussion focuses on the production of neutrinos by the Sun through various reactions, specifically detailing the proton-proton (pp), proton-electron-proton (pep), and helium-3-proton (hep) processes. A proposed new reaction, termed "heep," is introduced, which is expected to produce neutrinos at a high energy level. The intensity of the heep line and the branching ratios between the pp, pep, hep, and heep reactions are analyzed, with the consensus that the heep reaction is negligible compared to the others.

Sun produces neutrinos by sundry reactions:
p+p→d+e++νe - called "pp"
p+p+e→d+νe - called "pep"
3He+p→α+e++νe - called "hep"
3He+p+e→α+νe - never mentioned. What should it be called? "Heep"?
Now, heep neutrinos should form a sharp line at a quite high energy.
What is the intensity of heep line?
What is the branching ratio between pp and pep reactions?
What should be the branching ratio between hep and heep reactions?

It is not a branching ratio because it is not a decay. It depends on the star. As usual, Wikipedia has an article about it.

I would expect "heep" to be completely negligible, even hep has a tiny reaction rate.
