Abstract:
The nucleon and its structure are the
focus of intense study on all energy
scales, in both current and upcoming
experiments. It is one of the simplest
systems in non-perturbative QCD and
the accurate description of its
properties is a touchstone for
theoretical calculations.
Recent precision experiments have
provided a wealth of information, but
have also illuminated two glaring
discrepancies: the proton radius puzzle
and the form factor ratio divergence.
The former, still unsolved, may have
opened the door to the discovery of
physics beyond the Standard Model,
while a solution for the latter seems in
reach.
In this talk, I will discuss the Mainz high
precision form factor measurement
and global form factor analysis, which
are corner stones of the radius puzzle;
the OLYMPUS experiment, which is
poised to give the final confirmation of
the solution to the ratio problem; the
MUSE experiment, which will provide a
missing piece for the proton radius
puzzle; and the DarkLight experiment,
which will search for physics beyond
the Standard Model at the intensity
frontier.
