摘要:

我们建立了一个具有$SU(3)_C\otimes SU(2)_L\otimes U(1)_{Y^\prime}\otimes U(1)_{B-L}$规范对称性的超对称版本,其中$Y^\prime$是一个新的荷,$B$和$L$是通常的重子数和轻子数.该模型有三个右手中微子具有相同的$B-L$电荷,并可以容纳所有的费米子质量在树水平。特别是,I型跷跷板机制实现的活性中微子质量的产生。我们得到的所有部门的质谱和标量的,我们也给了模型所允许的平坦方向。

英文摘要:

We build a supersymmetric version with $SU(3)_C\otimes SU(2)_L\otimes U(1)_{Y^\prime}\otimes U(1)_{B-L}$ gauge symmetry, where $Y^\prime$ is a new charge and $B$ and $L$ are the usual baryonic and leptonic numbers. The model has three right-handed neutrinos with identical $B-L$ charges, and can accommodate all fermion masses at the tree level. In particular, the type-I seesaw mechanism is implemented for the generation of the active neutrino masses. We obtain the mass spectra of all sectors and for the scalar one we also give the flat directions allowed by the model.
