Two parity violating asymmetries from $np\to d\gamma$ in pionless effective field theories

Abstract

We consider parity-violating observables from the processes $\vec{n}p\to d\gamma$ and $np\to d\stackrel{\circlearrowleft }{\gamma }$. We perform calculations using pionless effective field theory both with and without explicit dibaryon fields. After combining these results with ones we have already obtained on parity-violating asymmetries in $\vec{N}N$ scattering, experimental input would in principle allow the extraction of all five parameters occurring at leading order in the parity-violating Lagrangian.
