85. Perspective on meson and baryon form factors

Dr Craig Roberts (Argonne)

2/2/17, 4:00 PM

Modern facilities are poised to tackle fundamental questions within the Standard Model, aiming to reveal the nature of confinement, its relationship to dynamical chiral symmetry breaking (DCSB) - the origin of visible mass - and the connection between these two, key emergent phenomena. There is strong evidence to suggest that they are intimately connected with the appearance of...

229. Perspective on experiments with meson form factors and exclusive meson production

Dr Tanja Horn (Catholic University of America)

2/2/17, 4:25 PM

Meson electroproduction data play an important role in our understanding of hadron structure and the dynamics that bind the basic elements of nuclear physics. Pion and kaon form factors are of particular interest as they are connected to the Goldstone modes of chiral dynamical symmetry breaking. The last decade saw a dramatic improvement in precision of charged pion form factor data and new...

228. Precision measurement of the proton elastic cross section at high $Q^2$

Longwu Ou (MIT)

2/2/17, 4:50 PM

The electromagnetic form factors (FF) are of fundamental importance in the investigation of nucleon structure and can be measured in high energy electron scattering experiments and interpreted in the framework of the one-photon exchange approximation. Current data on the proton form factors have significant statistical and systematic uncertainties at large $Q^2$, which limits the precision...

79. Pion form factor at high momentum transfer from lattice QCD

Bipasha Chakraborty (Jefferson Lab)

2/2/17, 5:15 PM

The pion electromagnetic form factor, $F_\pi$, is a fundamentally important topic for our understanding of the hadron structure and the transition from perturbative to nonperturbative QCD. JLAB’s experiment E12-06-101 proposes to extend the high quality $F_\pi$ data to $Q^2=6.0$ GeV$^2$ as a part of JLAB’s $12$ GeV upgrade. Being motivated by this, we present our ongoing lattice calculation of...
