For the public:
The aim of our research group is to study and understand certain aspects of the inner workings of the fundamental building blocks of matter (quarks). Quarks are not manifested as free particles in nature, therefore their study involves investigations of their stable combinations in particles, such as nucleons (protons and neutrons) as well as the particles which ``transmit'' the nuclear force among them, the mesons. Ultimately, the glue itself, which binds quarks, is also an objective of our investigations. In order to accomplish this goal, our group leads experimental efforts in the field of subatomic physics.
Nucleons and mesons, then, are composed of smaller, more fundamental particles, the quarks and gluons. As a result of the motion of the quarks (which produces magnetism) and their electrical charge, nucleons and mesons exhibit a distinct structure. We plan to map out this structure accurately, in order to test theoretical predictions and to provide valuable input to the interpretation of other experiments in the field. We have chosen the high energy electron beam at the Jefferson Lab, USA, for this mapping, because electrons do not have a composite structure of their own and are thus the cleanest probe to access the desired physics.
The nature of the interaction among quarks, on the other hand, is best investigated with photons (quanta of pure energy) through the production of exotic mesons which are not found in ordinary matter. These exotic mesons, called exotic hybrid mesons, carry unique signatures of the combinations of quarks and gluons. The investigation of exotic particles will be pursued at the proposed, new Hall D/GlueX facility at Jefferson Lab, which will take advantage of the future energy upgrade at this laboratory
