Query: Does a band structure affect sphaleron processes?   Inspired by a recent work of Tye and Wong, we examine an effect of a band
structure on baryon number preservation criteria requisite for successful
electroweak baryogenesis. Action of a reduced model is fully constructed
including a time component of the gauge field that is missing in the original
work. The band structure is estimated more precisely in wider energy range
based on WKB framework with three connection formulas to find that the band
structure has little effect on the criteria at around 100 GeV temperature. We
also address an issue of suppression factors peculiar to the $(B+L)$-changing
process in high-energy collisions at zero temperature.
