We consider light new particles $\chi$ and $\phi$ that carry baryon and lepton numbers. If these particles are lighter than nucleons they lead to exotic decays such as $p\to \pi^+ \chi$ and $p\to e^+\phi$, not yet fully constrained by dedicated searches. For $\chi$ and $\phi$ masses in the GeV range proton decays are kinematically forbidden but other decays of the forms baryon $\to$ meson$+\chi$, meson $\to$ baryon$+\bar\chi$, and baryon $\to$ anti-lepton$+\phi$ involving heavy initial hadrons are allowed. This opens up the possibility to search for apparent baryon number violation not just in underground experiments such as Super-Kamiokande and DUNE but also in decays of heavy hadrons in charm and B factories.

具有重子数和轻子数的轻粒子

我们考虑携带重子数和轻子数的轻新粒子 $\chi$ 和 $\phi$。如果这些粒子比核子轻,它们会导致奇异的衰变,例如 $p\to \pi^+ \chi$ 和 $p\to e^+\phi$,尚未完全受到专门搜索的限制。对于 GeV 范围内的 $\chi$ 和 $\phi$ 质量,质子衰变在运动学上是被禁止的,但是其他形式的重子 $\to$ 介子 $+\chi$、介子 $\to$ 重子 $+\bar\chi 的衰变$ 和重子 $\to$ 反轻子 $+\phi$ 涉及重初始强子是允许的。这为寻找明显的重子数违例提供了可能性,不仅在超级神冈和沙丘等地下实验中,而且在魅力和 B 工厂的重强子衰变中也是如此。
