Title: Anomalies in fundamental observables - old physics or new physics?
Speaker: Michael Kohl (Jefferson Lab).
Abstract: Anomalies in measurements of the proton elastic form factors,
the proton charge radius, and the muon magnetic moment have given rise
to speculations about missing elements of old or new physics, such
as two-photon exchange or the postulation of new particles still
to be discovered, which could also be linked to dark matter.
A framework of new experiments aims to resolve these puzzles by
stringently testing the offered hypotheses. I will discuss aspects
of the OLYMPUS, MUSE, TREK and DarkLight experiments and show how they
