For me this is a much needed antidote to drivel of No-Sci from the GOP and their rag-tag camp followers. Science Rules!
The Large Hadron Collector is back online. First collisions achieved on Nov. 23rd. LHC is a "big gun" to hunt for the "God Particle", the Higgs Boson. The Higgs is the only particle in the Standard Model of Particle Physics which hasn’t yet been detected.
They expect to ramp up to 1.2 TeV per beam to achieve the world’s highest energy collisions just before Christmas.
As time goes on and more collisions are made, we will record events in which the constituents of the protons collide with more energy, leading to sprays of particles transverse to the beam direction which we call “jets”. For example, a quark in one proton hitting an antiquark in the other proton with, say, a couple hundred GeV can produce two jets of 100 GeV going in opposite directions (from the beam’s eye view). Such dijet events will provide a very useful sample of data for aligning and calibrating the detector.Only after the beam intensity and the center of mass energy is a lot higher will we expect to see rarer and more interesting processes like W and Z boson production, and top quark pair production (top-antitop pairs). There are plans to collide at 2.4 TeV (higher than the 1.96 TeV at the Tevatron) before the end of the year if all goes well, and to 7 TeV early next year.
Beyond the God Particle ... Physicists at the Cosmic Variance blog have some fun with predictions. A interesting read on the cool soup of particle physics What Will the LHC Find?
