Abstract
The aim of these lectures will be to provide an introductory overview of the concepts needed to compute hadronic matrix elements on the lattice from which moments of Generalised Parton Distributions (GPDs) are extracted and to highlight the contributions that current lattice calculations are making to this exciting field of research. Interesting related topics that will be covered include recent work on the nucleon electromagnetic form factors and moments of parton distribution functions, including the nucleon's axial coupling constant, g_A, and the average fraction of the nucleon's momentum carried by the quarks, $\langle x_q\rangle$ .

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
