  Earlier estimates have argued that the baryon number violating scattering
cross-section in the laboratory is exponentially small so it will never be
observed, even for incoming 2-particle energy well above the sphaleron energy
of 9 TeV. However, we argue in arXiv:1505.03690 that, due to the periodic
nature of the sphaleron potential, the event rate for energies above the
sphaleron energy may be high enough to be observed in the near future. That is,
there is a discrepancy of about 70 orders of magnitude between the two
estimates. Here we argue why and how the multi-sphaleron processes are crucial
to the event rate estimate, a very important "resonant tunneling" property that
has not been taken into account before. We also summarize the input assumptions
and reasoning adopted in our estimate, when compared to the earlier estimates.
