LHC Update

From the physics blags, here’s a great post from John at Cosmic Variance, bringing you up to speed. Things get a little difficult at points, but I think it would still be a fun post to read, if you’re interested.

This past weekend the LHC crossed a major threshold: 1 inverse picobarn delivered to the experiments – a factor of a thousand more collisions. By late next year we are all hoping to have recorded another factor of a thousand, for a total of 1 inverse femtobarn.

In an earlier post I explained these funny units, inverse whatever-barns. The point here, though, is that as we record exponentially greater numbers of collision events, with the proton beam energy 3.5 times greater than that at the Tevatron at Fermilab we will begin to really probe an unexplored mass scale in the search for new particles. What lies there is completely unknown.

Also. I love the Onion, as you should too. Here’s an awesome article — “Scientists Ask Congress to Fund $50 Billion Science Thing” — from 2007 that I thiiiink is referring to the Superconducting Super Collider (sadest story every told).
