Possible contributions to neutrinoless double beta (ßß)0? decay in the economical 3-3-1 modelare discussed. We show that the (ßß)0? decay in this model is due to both sources—MajoranaL and Dirac D neutrino masses. If the mixing angle between charged gauge... see more

The BRST Charge plays a prominent role in interaction theory based on the Gaugesymmetry group. In this work we find the explicit expression of the BRST charge for Generalizeddeformed SU(2) algebra.

Superluminal electromagnetic fields of dyons are described in T^{4}- space and Quaternion formulation of various quantum equations is derived. It is shown that on passing from subluminal to superluminal realm via quaternion the theory of dyons becomes the... see more

Recently, striking effects of light irradiation on the magnetic state were reported for Prussian blue (PB) analogues AxCoy[Fe(CN)6] (A = Na, K, Rb, Cs). The physical and optical properties of these compounds are dependent on the size of the particles of t... see more
