The experiment is approved and in preparation at he Spallation Neutron Source, at Oak Ridge National Laboratory, in Tennessee, USA. It is the last one in a series of four experiments needed to provide a self-consistent description of the hadronic weak interaction (HWI) using few-body systems alone.
The experiment is approved and in preparation at the Spallation Neutron Source, at Oak Ridge National Laboratory, in Tennessee, USA. It is the last one in a series of four experiments needed to provide a self-consistent description of the hadronic weak interaction (HWI) using few-body systems alone. Beam time has been allocated, tentatively starting in the early Fall of 2014.
The aim is to measure the asymmetry to 10% of its predicted size, with an approximate running time of 1 beam year.

Recent theoretical calculations ( PRC) show that the asymmetry is related to a linear combination of weak hadronic couplings involving pion, \rho, and \omega meson exchange:
The measurement observable is the parity violating forward-backward asymmetry in the number of protons emitted in the breakup of the intermediate ^{4}He state, for a beam of longitudinally polarized, cold neutrons:
