The measurement of electric dipole moment in storage rings can potentially exceed the sensitivity tests with neutral systems. spin dynamics under such conditions is described by Bargmann-Michel-Telegdi equation. It be derived semiclassical approximation several assumptions one which zero pseudoscalar bilinear. However, many promising extensions to standard model consider scalar-pseudoscalar cou...

We propose to test CP symmetry in the decay J/ψ → γφφ, for which large data sample exists at BESII, and a data sample of 10 10 J/ψ's will be collected with BESIII and CLEO-C program. We suggest some CP asymmetries in this decay mode for CP test. Assuming that CP violation is introduced by the electric-and chromo-dipole moment of charm quark, these CP asymmetries can be predicted by using valenc...

We consider a Dirac one-electron atom placed in a weak, static, uniform magnetic field. We show that, to the first order in the strength B of the perturbing field, the only electric multipole moment induced by the field in the ground state of the atom is the quadrupole one. Using the Sturmian expansion of the generalized Dirac–Coulomb Green function [R. Szmytkowski, J. Phys. B 30 (1997) 825; er...

Nuclear processes involving momenta much below the mass of the pion may be described by an effective field theory in which the pions do not appear as explicit degrees of freedom. The effects of the pion and all other virtual hadrons are reproduced by the coefficients of gauge-invariant local operators involving the nucleon field. Nucleon-nucleon scattering phase shift data constrains many of th...

We report on the focusing and guiding of the van der Waals complex formed between benzonitrile molecules (C(6)H(5)CN) and argon atoms in a cold molecular beam using an ac electric quadrupole guide. The distribution of quantum states in the guided beam is non-thermal, because the transmission efficiency depends on the state-dependent effective dipole moment in the applied electric fields. At a s...

A fundamentally new understanding of the classical electromagnetic interaction of a point charge and a magnetic dipole moment through order v/c is suggested. This relativistic analysis connects together hidden momentum in magnets, Solem’s strange polarization of the classical hydrogen atom, and the Aharonov-Bohm phase shift. First we review the predictions following from the traditional particl...

Searches for CP-violating effects in atoms and molecules provide important constrains on competing extensions to the standard model of elementary particles. In particular, CP violation in an atom leads to the CP-odd T,P-odd polarizability CP: a magnetic moment CP is induced by an electric field E0 applied to an atom, CP= E0. We estimate the CP-violating polarizability for rare-gas diamagnetic a...
