| Outline of Final Research Achievements |
This project has made progress in (i) physics beyond the standard model (BSM) and (ii) early universe from the point of view of BSM physics. For (i), we have performed a full one-loop calculation the electroweak vacuum. We have also established a procedure to calculate the decay rate of false vacuum in a gauge invariant way. For (ii), we have studied the effects of light long-lived unstable particles on big-bang nucleosynthesis. In addition, using the knowledges about the BSM physics from the studies of (i) and (ii), we have proposed several new ideas of discovering the signals of BSM physics.
