The Hadronic Physics Group (HPG) conducts medium to high energy nuclear physics experiments in diverse research facilities in the world, including the Brookhaven National Laboratory (BNL), the DESY Laboratory, Thomas Jefferson National Accelerator Facility (TJNAF), The Johannes Gutenberg University of Mainz, Los Alamos National Laboratory (LANL), and the Oak Ridge National Laboratory (ORNL). The group has a leading role in the LHCb experiment at the Large Hadron Collider (LHC) at CERN.
The main topic of the group is to probe the structure of protons, neutrons, and other hadrons in order to address a variety of questions, examples of which regard perturbative and/or non-perturbative QCD, the Standard Model of electroweak interaction and models of the early universe.

Nuclear Physics News International, Volume 28, Issue 1, January - March, 2018 fea-tured an article on the OLYMPUS Experiment at DESY. This was an experiment lead by researchers from the MIT LNS Hadronic Physics Group to measure the contri-bution from two-photon exchange in lepton-proton scattering. This process is widely believed to be the cause of the striking discrepancy in the proton form factor ratio measured using polarized and unpolarized techniques. The OLYMPUS results, with results from two other experiments, measured only a small, ⟨ 1%, effect. This was less than expected from theoretical calculations but is consistent with the measure-ments in the momentum transfer regime measured. Experiments at higher energies and further theoretical work are still needed to understand the observed discrepancy in the proton form factor ratio.

A search for dark photons at the LHC comes up empty but puts new constraints on the strength of the hypothetical particles’ coupling to electromagnetic fields. Dark matter is aptly named. It emits no light and interacts with visible matter only via gravity. But dark matter might be only the tip of an invisible universe of unknown forces.

Nuclear Physics News International
The October-December 2017 quarterly issue of Nuclear Physics News International contains several items directly relevant to the Hadronic Physics Group. The laboratory portrait is of the MIT Bates Laboratory and is written by Bates Director Bob Redwine. The cover photo shows the Qweak toroid, which was designed, constructed and commissioned at Bates. Stanley Kowalski is co-spokesman of the Qweak collaboration. The editorial in this issue was written by Richard Milner. Finally, the issue contains an obituary for our late MIT faculty colleague Arthur Kerman by Ernie Moniz.

BLAST Quasielastic (e,e’p) Vector and Tensor Asymmetries Reported in Physical Review Letters
Over twelve years after data taking with the Bates Large Acceptance Spectrometer Toroid (BLAST) was completed, a paper by the BLAST collaboration reporting on vector and tensor asymmetries in quasielastic (e,e’p) scattering from deuterium was published in the November 3, 2017 edition of Physical Review Letters. The results provide new constraints both on the spin structure of the deuteron and the role of the tensor force in the neutron-proton final-state interaction. The work was based on the Ph.D. theses of MIT students Adam DeGrush and Aron Maschinot (supervised by Robert Redwine). The principal authors of the paper were Ricardo Alarcon, Douglas Hasell and Richard Milner.
