Universal behavior of $p$-wave proton-proton fusion near threshold

14 Aug 2019 Acharya Bijaya Platter Lucas Rupak Gautam

We calculate the $p$-wave contribution to the proton-proton fusion $S$ factor and its energy derivative in pionless effective field theory (EFT) up to next-to-leading order. The leading contributions are given by a recoil piece from the Gamow-Teller and Fermi operators, and from relativistic $1/m$ suppressed weak interaction operators... (read more)
