Relations between fine structure constants based on diagonal subgroup
breaking and degenerate vacua.


Datum: 20. prosinca 2006. (srijeda)
Vrijeme: 11.00 c.t.
Mjesto: PMF, Fizički odsjek, Bijenička c. 32, F-201

Sažetak:

Our attempt to "fit" the three fine structure constants, for the three
gauge groups, extrapolated to the Planck scale in a model based on
the assumption of degenerate vacua and what we called AntiGUT model
makes progress w.r.t. accuracy. We have a relation which may be claimed
to tell the U(1) fine structure constant to about 2 % accuracy.
Is the fitting now so good that you should take the model seriously?
