We consider a neutrino mass generating model which employs scalar leptoquark, Δ, and diquark, S. The new scalars Δ S carry the standard SU(3) c × SU(2) L U(1) Y quantum numbers (3, 1, −1/3) (6, −2/3), respectively. masses are generated at two-loop level, as in Zee-Babu [1, 2], Δ/S plays role of doubly/singly charged model. With moderate working assumption that magnitudes six Yukawa couplings between down-type quarks same order, strong connections found lepton flavor violating processes. In...
We propose a type of hybrid Seesaw model that combines Type-1 and Type-2 mechanism in multiplicative way to generate tree level Majorana neutrino mass provides Dark Matter candidate. The extends the Standard Model by extra gauge symmetry U(1)D hidden sector consisted chiral fermions additional scalar fields. After spontaneous breaking, light masses are generated not only exchange new heavy as Seesaw, but also coupling naturally small induced vacuum expectation value Seesaw. An unbroken...
A simple renormalizable $U(1)$ gauge model is constructed to explain the smallness of active neutrino masses and provide stable cold dark matter candidate simultaneously. The local symmetry assumed be spontaneously broken by a scalar field around TeV scale. are then generated at one-loop level. This contains several candidates whose stability guaranteed residual discrete ${Z}_{2}$ \`a la Krauss-Wilczek mechanism. Unlike other models, no further global or continuous introduced. Moreover, all...
Abstract The flow associated with the sublimation and condensation of carbon dioxide ice in polar regions Mars is an important part general circulation. However, so far pattern generally not well known. In this study, a circulation model (MarsWRF) has been applied to derive based on some specially designed experiments. results suggest that equatorward poleward flows both hemispheres are rather shallow except near poles, strength significantly stronger than hemispheres. also show southern...
Airborne dust is an important constituent in the Martian atmosphere because of its radiative interaction with atmospheric circulation, and size one crucial factor determining this effect. In numerical modeling processes, description usually dependent on choice a particular distribution function, or fixed values effective radius (ER) variance (EV) though they are variable reality. work, analytical expressions have been derived to specify ER EV for N-bin schemes based model calculated mixing...
