Title: How can we know about GUT?
Place: ES635& ZOOM

Abstract:  The grand unified theory (GUT) can explain, “Why a charge of proton is the same as minus charge of electron to an accuracy of 10^{^21}?”. It is a great candidate of “beyond the standard model”. But, there are too many possibilities of GUT. How can we know about GUT? I will speak about some approaches of our recent researches to know the GUT.
