在等单重态标量轻子非零真空期望值诱导的标准SU(2)⊗U(1)超对称模型中,提出了一个自发R宇称破缺模型。R宇称破缺发生在电弱尺度上,不需要微调以抑制由于主发射引起的恒星能量损失,也不需要标量对不可见的Z衰变宽度的贡献。τ中微子可能非常重,并且在实验中可能存在可观察到的破坏风味过程的速率。
We suggest a model for spontaneous R parity breaking in the standard SU (2) ⊗ U (1) supersymmetric model induced by non-zero vacuum expectation values (VEVs) for isosinglet scalar leptons. R parity breaking occurs at the electroweak scale with no fine-tuning required in order to suppress stellar energy loss due to majoron emission and no contribution of scalars to the invisible Z decay width. The τ neutrino may be very heavy and there may be experimentally observable rates for flavour-violating processes.
