Anomaly-induced Quadrupole Moment of the Neutron in Magnetic Field

, 2011
The neutrons cannot possess a quadrupole moment in the vacuum. Nevertheless, we show that in the presence of an external magnetic field the neutrons acquire a new type of quadrupole moment $Q^{ij}= \chi\,\sigma^i B^j$ involving the components of spin and

Beyond the soft photon approximation in radiative production and decay of charged vector mesons [PDF]

, 2001
We study the effects of model-dependent contributions and the electric quadrupole moment of vector mesons in the decays $V^- \to P^-P^0\gamma$ and $\tau^- \to \nu V^-\gamma$.

Ground-state electric quadrupole moment of 31Al

, 2008
Ground-state electric quadrupole moment of 31Al (I =5/2+, T_1/2 = 644(25) ms) has been measured by means of the beta-NMR spectroscopy using a spin-polarized 31Al beam produced in the projectile fragmentation reaction. The obtained Q moment, |Q_exp(31Al)|

The Nambu-Jona-Lasinio model of light nuclei [PDF]

, 2000
The Nambu-Jona-Lasinio model of the deuteron suggested by Nambu and Jona-Lasinio (Phys. Rev. 124 (1961) 246) is formulated from the first principles of QCD. The deuteron appears as a neutron-proton collective excitation, i.e. a Cooper np-pair, induced by

Electric dipole and magnetic quadrupole moments of the $W$ boson via a CP-violating $HWW$ vertex in effective Lagrangians

, 2005
The possibility of nonnegligible $W$ electric dipole ($\widetilde{\mu}_W$) and magnetic quadrupole ($\widetilde{Q}_W$) moments induced by the most general $HWW$ vertex is examined via the effective Lagrangian technique.

CP-odd static electromagnetic properties of the W gauge boson and the t quark via the anomalous tbW coupling

, 2007
In the framework of the electroweak chiral Lagrangian, the one-loop induced effects of the anomalous $tbW$ coupling, which includes both left- and right-handed complex components, on the static electromagnetic properties of the $W$ boson and the $t ...

Multipole Moments of Fractal Distribution of Charges

, 2005
In this paper we consider the electric multipole moments of fractal distribution of charges. To describe fractal distribution, we use the fractional integrals. The fractional integrals are considered as approximations of integrals on fractals.

Fano resonances in plasmonic core-shell particles and the Purcell effect

, 2018
Despite a long history, light scattering by particles with size comparable with the light wavelength still unveils surprising optical phenomena, and many of them are related to the Fano effect.

Electric dipole and quadrupole contributions to valence electron binding in a charge-screening environment

, 2018
We make a multipole expansion of the atomic/molecular electrostatic charge distribution as seen by the valence electron up to the quadrupole term. The Tridiagonal Representation Approach (TRA) is used to obtain an exact bound state solution associated ...
