We analyze the real photon asymmetry $A^\pm_\gamma$ for the parity violating (PV) $\pi^\pm$ production on the $\Delta$ resonance via the reactions ${\vec \gamma} + p \to \Delta^+ \to \pi^+ + n$ and ${\vec \gamma} + d \to \Delta^0 + p \to…

The status of the field of nuclear parity violation---both experimental and theoretical---is reviewed, with special emphasis on those results which have been obtained since the 1985 review article by Adelberger and Haxton.

Non-Standard-Model parity violation may be occurring in LHC collisions. Any such violation would go unseen, however, as searches are for it are not currently performed. One barrier to searches for parity violation is the lack of…

The parity-non-conserving (pnc) asymmetry in \vec{n} + p \to d+\gamma at thermal energies has recently been calculated using effective field-theory methods. A comparison of this calculation with much more elaborate calculations performed in…

We calculate the parity-violating nucleon-nucleon potential in heavy-baryon chiral perturbation theory up to the next-to-next-to-leading order. The one-pion exchange comes in the leading order and the next-to-next-to-leading order consists…
