Extraction of a_nn from pi- d -> n n gamma

Preprint English OPEN
Gardestig, Anders;
(2006)

I present a calculation of the pi- d -> n n gamma reaction to third order in chiral perturbation theory. The short-distance physics of this reaction can be constrained by relating it to several important low-energy weak reactions. The theoretical error in a_nn extracted... View more
