Is this reaction possible in the star?

I've heard many things about the fusion in the star.
But recent cosmic data say vary high energy Gamma ray emission occurring in the Universe.
Some research said its related to the Dark Matter annihilation.
I'm weakly afraid of saying about that, but.
Is one of them related to particle fusion, proton-proton, proton-neutron, neutron-neutron?

[zhermes]

nope.
