The anapole moment and nucleon weak interactions

چکیده
From the recent measurement of parity nonconservation (PNC) in the Cs atom we have extracted the constant of the nuclear spin dependent electron-nucleon PNC interaction, κ = 0.44(7); the anapole moment constant, κa = 0.38(7); the strength of the PNC proton-nucleus potential, gp = 7 ± 1.4 (exp.) ± 1.5 (theor.); the π-meson-nucleon interaction constant, fπ ≡ hπ = [10 ± 2.5 (exp.) ± 3.5 (theor.)] × 10 −7; and the strength of the neutron-nucleus potential, gn = −2± 1.0 (exp.)± 1.3 (theor.).

The Nucleon Anapole Moment and Parity-Violating ep Scattering
Parity-violating (PV) interactions among quarks in the nucleon induce a PV γNN coupling, or anapole moment (AM). We compute electroweak gauge-independent contributions to the AM through O(1/Λχ) in chiral perturbation theory. We estimate short-distance PV effects using resonance saturation. The AM contributions to PV electron-proton scattering slightly enhance the axial vector radiative correcti...
متن کاملConsistency of parity - violating pion - nucleon couplings extracted from measurements in 18 F and 133 Cs
The recent measurement of the nuclear anapole moment of 133 Cs has been interpreted to yield a value of the weak pion-nucleon coupling H 1 π which contradicts the upper limit from the 18 F experiments. We argue that because of the sensitivity of the anapole moment to H 0 ρ in the odd proton nucleus 133 Cs, there is a combination of weak meson-nucleon couplings which satisfies both experiments a...
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 کاملNuclear anapole moments
Nuclear anapole moments are parity-odd, time-reversal-even E1 moments of the electromagnetic current operator. Although the existence of this moment was recognized theoretically soon after the discovery of parity nonconservation ~PNC!, its experimental isolation was achieved only recently, when a new level of precision was reached in a measurement of the hyperfine dependence of atomic PNC in Cs...
متن کاملParity 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.
