Large Momentum Transfer Measurements of the Deuteron Elastic Structure Function A(Q^2) at Jefferson Laboratory

The Jefferson Lab Hall A Collaboration, L. C Alexa

The deuteron elastic structure function A(Q^2) has been extracted in the Q^2 range 0.7 to 6.0 (GeV/c)^2 from cross section measurements of elastic electron-deuteron scattering in c…

PU(2) monopoles and a conjecture of Marino, Moore, and Peradze

Paul M. N. Feehan, Peter B. Kronheimer, Thomas G. Leness +1

In this article we show that some of the recent results of Marino, Moore, and Peradze (math.DG/9812042, hep-th/9812055) -- in particular their conjecture that all closed, smooth fo…

Inclusive Electron-Nucleus Scattering at Large Momentum Transfer

J. Arrington

Inclusive electron scattering is measured with 4.045 GeV incident beam energy from C, Fe and Au targets. The measured energy transfers and angles correspond to a kinematic range fo…
