Shining a light on strongly interacting matter
The talk will outline current Edinburgh led research programmes which exploit high intensity energy-tagged gamma beams at the MAMI facility in Germany and Jefferson Lab in the USA. These experiments aim to improve our understanding of strongly interacting matter through the study of composite systems at both the nuclear and nucleon scales. The talk will include new results which constrain poorly established parameters in the equation of state for neutron rich matter, with a discussion of the implications of the results for neutron star structure and cooling mechanisms. Our contribution to the worldwide effort to improve our knowledge of the excitation spectrum of the nucleon through complete measurements of polarisation observables in meson photoproduction from the nucleon will also be discussed.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
