Reevaluation of Neutron Electric Dipole Moment with QCD Sum Rules

open access: yes, 2012
We study the neutron electric dipole moment in the presence of the CP-violating operators up to the dimension five in terms of the QCD sum rules. It is found that the OPE calculation is robust when exploiting a particular interpolating field for neutron,

Search for Axionlike Dark Matter through Nuclear Spin Precession in Electric and Magnetic Fields

open access: yesPhysical Review X, 2017
We report on a search for ultralow-mass axionlike dark matter by analyzing the ratio of the spin-precession frequencies of stored ultracold neutrons and ^{199}Hg atoms for an axion-induced oscillating electric dipole moment of the neutron and an axion ...

Dipole operator constraints on composite Higgs models

open access: yes, 2014
Flavour- and CP-violating electromagnetic or chromomagnetic dipole operators in the quark sector are generated in a large class of new physics models and are strongly constrained by measurements of the neutron electric dipole moment and observables ...

P-odd and CP-odd Four-Quark Contributions to Neutron EDM

open access: yes, 2010
In a class of beyond-standard-model theories, CP-odd observables, such as the neutron electric dipole moment, receive significant contributions from flavor-neutral P-odd and CP-odd four-quark operators.

Suppressed electric quadrupole collectivity in 49Ti

open access: yesPhysics Letters B
Single-step Coulomb excitation of 46,48,49,50Ti is presented. A complete set of E2 matrix elements for the quintuplet of states in 49Ti, centred on the 2+ core excitation, was measured for the first time.

CP Conservation in the Strong Interactions

open access: yesUniverse
We discuss matters related to the point that topological quantization in the strong interaction is a consequence of an infinite spacetime volume. Because of the ensuing order of limits, i.e., infinite volume prior to summing over topological sectors, CP ...
