We estimate the relative contribution of nuclear structure and new physics couplings to the parity non-conserving spin-independent effects in atomic systems, for both single isotopes and isotopic ratios. General expressions are presented to assess the sensitivity of isotopic ratios to neutron skins and to couplings beyond standard model at tree level. The specific coefficients for these contributions are calculated assuming Fermi distribution for proton and neutron nuclear densities for…

Determining the nuclear neutron distribution from Coherent Elastic neutrino-Nucleus Scattering: current results and future prospects

Coherent elastic neutrino-nucleus scattering (CE$\nu$NS), a process recently measured for the first time at ORNL's Spallation Neutron Source, is directly sensitive to the weak form factor of the

Neutrino, electroweak, and nuclear physics from COHERENT elastic neutrino-nucleus scattering with refined quenching factor

We present an updated analysis of the coherent neutrino-nucleus elastic scattering data of the COHERENT experiment, taking into account the new quenching factor published recently in [Phys. Rev. D

Atomic Physics Studies at the Gamma Factory at CERN

The Gamma Factory initiative proposes to develop novel research tools at CERN by producing, accelerating, and storing highly relativistic, partially stripped ion beams in the SPS and LHC storage



Neutron density distributions for atomic parity nonconservation experiments

Nuclear structure corrections to the weak charge in atomic parity nonconservation (PNC) experiments are analyzed. Measurement of PNC effects along an isotope chain might represent a useful method to

Nuclear-structure effects in atomic parity nonconservation.

It has been suggested to measure ratios of atomic parity-nonconservation observables in strings of isotopes to cancel atomic-structure effects to help extract weak-interaction parameters.

Reevaluation of the role of nuclear uncertainties in experiments on atomic parity violation with isotopic chains

In light of new data on neutron distributions from experiments with antiprotonic atoms [Trzcinska et al., Phys. Rev. Lett. 87, 082501 (2001)], we reexamine the role of nuclear-structure uncertainties

Effect of nuclear quadrupole moments on parity nonconservation in atoms

Nuclei with spin $I \ge 1$ have a weak quadrupole moment which leads to tensor contribution to the parity non-conserving interaction between nuclei and electrons. We calculate this contribution for

Isotopic variation of parity violation in atomic ytterbium

The weak force is the only fundamental interaction known to violate the symmetry with respect to spatial inversion (parity). This parity violation can be used to isolate the effects of the weak

Low-energy parity-violation and new physics

The new physics sensitivity of a variety of low-energy parity-violating (PV) observables is analyzed. A comparison is made between atomic PV for a single isotope, atomic PV using isotope ratios, and

Precision determination of electroweak coupling from atomic parity violation and implications for particle physics.

This is the most accurate to-date test of the low-energy electroweak sector of the SM and increases the lower limit on the masses of extra Z bosons predicted by models of grand unification and string theories.

Measurement of the neutron radius of 208Pb through parity violation in electron scattering.

The first measurement of the parity-violating asymmetry A(PV) in the elastic scattering of polarized electrons from 208Pb is reported, which provides the first electroweak observation of the neutron skin which is expected in a heavy, neutron-rich nucleus.

Probing Low-Mass Vector Bosons with Parity Nonconservation and Nuclear Anapole Moment Measurements in Atoms and Molecules.

From measured and predicted values for the PNC amplitudes in Cs, Yb, and Tl, as well as the nuclear anapole moment of ^{133}Cs, this work constrain the P-violating vector-pseudovector nucleon-electron anducleon-proton interactions mediated by a generic vector boson of arbitrary mass.


A parametric approach to the effects of finite nuclear size in atomic parity nonconservation (PNC) is developed. Rose's integral form of the electronic wavefunction is used to obtain a complete (Z)2
