Abstract:
In the Standard Model of Particle Physics there are 28
fundamental constants. In the experiments these constants can be measured, but theoretically
they are not understood.
I will discuss these constants, which are mostly mass parameters.
Astrophysical measurements indicate that the finestructure constant
depends on time. Grand unification implies a time variation of the QCD scale.
Thus the masses of
the
atomic nuclei and the magnetic moments of the nuclei will depend on
time.
I proposed an experiment, which is currently done by Prof. Haensch in
Munich and his group. The first results indicate a time dependence of
the
QCD scale. Theoretical implications will be discussed.
