The littlest Higgs model with T-parity, which is called LHT model, predicts the existence of the new particles, such as heavy top quark, heavy gauge bosons, and mirror fermions. We calculate the one-loop contributions of these new particles to the top quark chromomagnetic dipole moment (CMDM) ∆K. We find that the contribution of the LHT model is one order of magnitude smaller than the standard ...

We present a simple analysis that allows us to extract the leading mass dependence of the dipole moment of matter fermions that might be induced by new physics. We present explicit results for the supersymmetric model with broken R-parity as an illustration. We show that the extra contributions to the electric dipole moment(edm) of fermions from Rp / interactions can occur only at two loop leve...

We report on differential and integral cross section measurements for the electron impact excitation of the three lowest lying Rydberg bands of electronic states in tetrahydrofuran. The energy range of the present experiments was 15-50 eV with the angular range of the differential cross section measurements being 15°-90°. The important effects of the long-range target dipole moment and the targ...

The energy flow lines (field lines of the Poynting vector) of electric dipole radiation exhibit a vortex structure in the near field when the dipole moment of the source is in circular rotation. The spatial extend of this vortex is smaller than a wavelength and may not be observable by a measurement in the near field. We show that the rotation of the field lines close to the source affects the ...

A search for the electron electric dipole moment d, is carried out with two counterpropagating beams of ground-state 'Tl. The experiment employs atomic-beam magnetic resonance with separated oscillatory fields combined with laser state selection and fluorescence detection. Extensive tests were made for possible systematic effects. The result for the atomic electric dipole moment is d, =(1.6+'5....

The charge-density distribution in 2H-chromene-2-thione (2-thiocoumarin), C(9)H(6)OS, has been determined from X-ray diffraction data measured at 90 K using a CCD detector, to a resolution of sintheta/lambda < 1.08 A(-1). A multipolar-atom density model was fitted against 6908 reflections with I > 2sigma(I) [R(F) = 0.021, wR(F) = 0.022, goodness of fit = 1.81] in order to generate the differenc...

The role of molecular dipole moment, charge transfer, and Pauli repulsion in determining the work-function change (Deltaphi) at organic-metal interfaces has been elucidated by a combined experimental and theoretical study of (CH(3)S)(2)/Au(111) and CH(3)S/Au(111). Comparison between experiment and theory allows us to determine the origin of the interface dipole layer for both phases. For CH(3)S...

The error in the molecular dipole moment as derived from accurate X-ray diffraction data is shown to be origin dependent in the general case. It is independent of the choice of origin if an electroneutrality constraint is introduced, even when additional constraints are applied to the monopole populations. If a constraint is not applied to individual moieties, as is appropriate for multicompone...

We present a review of the masses (except for neutrino masses) and interaction strengths in the standard model. Special emphasis is put on quantities that have been determined with significantly improved precision in the last few years. In particular, a number of determinations of αs and the electromagnetic coupling on the Z, αQED(M 2 Z) are presented and their implications for the Higgs mass d...
