A very important new theoretical study has appeared last Tuesday in the hep-ph preprint arxiv. Titled "Precise Predictions on W+4 Jet Production at the Large Hadron Collider", it is signed by a strong team of theorists: C. Berger, Z. Bern, L. Dixon, F. Febres Cordero, D. Forde, T. Gleisberg, H. Ita, D. Kosower, and D. Maitre.

I believe it may be quite useful if I review here the paper results, and explain to you why they are very important for the physics of the LHC. But first, I feel that there are a few details concerning the process of W+jets production at the LHC which might be obscure to most of you. Let me straighten them out -it is worthwhile to do it!

Preliminaries

I occasionally get questions about usage of Science 2.0 that go beyond the FAQ so I decided I would write up a short article on using the site for non-beginners.   The FAQ covers the basics - what Science 2.0® is, the experimental nature of this open writing site for science, etc. along with the basic functionality, like the dashboard - but due to the way the site has grown some other features may not be evident for newer members.

How to find good stuff to write about?
