  In the framework of nuclear physics and at nuclear physics facilities a large
number of different experiments can be performed which render the possibility
to investigate fundamental symmetries and interactions in nature. In
particular, the precise measurements of properties of fundamental fermions,
searches for new interactions in $\beta$-decays, and violations of discrete
symmetries have a robust discovery potential for physics beyond standard
theory. Precise measurements of fundamental constants can be carried out as
well. Low energy experiments allow probing of New Physics models at mass scales
far beyond the reach of present accelerators or such planned for the future in
the domain of high energy physics and at which predicted new particles could be
produced directly.
