在弱电弦背景下，重子数反常方程可以重新解释为重子数减螺旋度的守恒定律。由于螺旋度是链数和扭数的总和，所以弱电弦的连接或扭环携带重子数。我们估算了弱电弦脱链环所得到的重子数的变化，表明扭曲的弱电弦段可以看作是扩展的闪子。我们还提出了弱电重子发生的另一种情景。
In the context of electroweak strings, the baryon number anomaly equation may be reinterpreted as a conservation law for baryon number minus helicity. Since the helicity is a sum of the link and twist numbers, linked or twisted loops of electroweak string carry baryon number. We evaluate the change in the baryon number obtained by delinking loops of electroweak [ital Z] string and show that twisted electroweak string segments may be regarded as extended sphalerons. We also suggest an alternative scenario for electroweak baryogenesis.
