Abstract:
A big challenge in modern nuclear physics is to
treat all parts of a given calculation with great
rigor and consistency, thus allowing for a full
understanding and quantification of theoretical
uncertainties.
Aspects of this issue concern both computational
methods as well as the nuclear interaction itself --
and possibly an interplay between these. A
connecting theme is typically an entanglement of
physics at short and long distance scales that has
to be understood. In this talk, I will give an
overview of some developments along these
lines, ranging from extrapolation techniques on
the calculational side, to questions of consistent
renormalization in nuclear effective field theory
(EFT) on the fundamental one. I will focus on the
so-called pionless effective field theory, which can
be used as a controlled laboratory to study issues
of general importance.
