Parity Violation in Low - Energy np → dγ and the Deuteron Anapole Moment
نویسنده
چکیده
Parity violation in low-energy nuclear observables is included in the pionless effective field theory. The model-independent relation between the parityviolating asymmetry in ~np → dγ and the non-nucleon part of the deuteron anapole moment is discussed. The asymmetry in ~np → dγ computed with KSW power-counting, and recently criticized by Desplanques, is discussed.

Parity Violation in Effective Field Theory and the Deuteron Anapole Moment
Effective field theory, including pions, provides a consistent and systematic description of nucleon-nucleon strong interactions up to center-of-mass momentum p ∼ 300 MeV per nucleon. We describe the inclusion of hadronic parity violation into this effective field theory and find an analytic form for the deuteron anapole moment at leading order in the expansion.
متن کاملMeasurement of Parity Nonconservation and an Anapole Moment in Cesium
The amplitude of the parity-nonconserving transition between the 6S and 7S states of cesium was precisely measured with the use of a spin-polarized atomic beam. This measurement gives Im(E1pnc)/beta = -1.5935(56) millivolts per centimeter and provides an improved test of the standard model at low energy, including a value for the S parameter of -1.3(3)exp (11)theory. The nuclear spin-dependent ...
متن کاملThe Nucleon Anapole Form Factor in Chiral Perturbation Theory to Sub-leading Order
The anapole form factor of the nucleon is calculated in chiral perturbation theory to sub-leading order. This is the lowest order in which the isovector anapole form factor does not vanish. The anapole moment depends on counterterms that reflect short-range dynamics, but the momentum dependence of the form factor is determined by pion loops in terms of parameters that could in principle be fixe...
متن کاملThe Anapole Moment of the Deuteron with the Argonne v18 Nucleon-Nucleon Interaction Model
We calculate the deuteron anapole moment with the wave functions obtained from the Argonne v18 nucleon-nucleon interaction model. The anapole moment operators are considered at the leading order. To minimize the uncertainty due to a lack of current conservation, we calculate the matrix element of the anapole moment from the original definition. In virtue of accurate wave functions, we can obtai...
متن کاملThe Anapole Form Factor of the Deuteron
We find the leading order result for the anapole form factor of the deuteron using effective field theory. The momentum dependence of the anapole form factor is different from that of the matrix element of the strange currents in the deuteron, which may provide a way for disentangling these two competing effects when analyzing parity violating electron-deuteron scattering experiments. We give c...
