CPT-Violating Model of Weak Interactions

We study a model of weak interactions in which the divergences are no worse than those of the renormalizable theory and the $\mathrm{CPT}$ invariance is maximally violated. The model is consistent with all existing data, and some data favor our predictions over those of conventional theories. In particular, the model predicts that the lifetime of ${\Lambda }^0$ decaying in flight at 100 GeV will be shorter than that measured at rest by ∼ 16%, a prediction which can be tested at the National Accelerator Laboratory.
