Evidence of Higgs boson

I've been a bit remiss with my blogging of late and managed to miss discussing this pretty big story. CERN, the European particle physics group, has evidence that there might be Higgs particles. What are Higgs? Well, they are theorized to provide mass to all other particles. Not only has CERN reported this, but Tevatron in Chicago at Fermilab has reported seeing similar, but smaller results. This is very good news. In fact, despite the fact that Tevatron (6.3km) is no where near the size of Large Hadron Colider (LHC) of CERN (27km), which means that it can produce less power, can detect it means that there's a lot of room for further investigation at LHC. This is exciting.

What if Higgs doesn't exist? Well, basically it means that the Standard Model of particle physics is partially scrapped. Only partially, because a lot of the theory has been supported through the research at institutions like CERN and Fermilab. However, the evidence is pretty good, however, the scientists are being extremely cautious. They are currently at 2.8 sigma on a normal curve (bell curve for grading). For most research this error rate is more than enough for it to be considered a significant finding, 99.9% likelihood, however in particle physics significantly higher results are required. They require 5 sigma, which is about 1 in a million.

Does this impact my daily life? No not really, however I'm very sure whenever some of the original atomic theories were put forward and verified, most people didn't see much use in them. It might take us a large amount of time to figure out how to actually use this. For all we know some of these developments may lead to a better understanding of fission in some way. I'm speculating of course, but there's no reason to assume that this research is good for just doing more research.

In the United States cutting edge particle research is drawing to a close I'm afraid. In October of 2011 Tevatron will shut down for good, and there are only a few other large accelerators in the US, none as large as Tevatron.This will likely have long term impacts on both theoretical physics and particle physics in the US. The expertise will leave Universities like University of Chicago and move over to Europe to work with CERN. This didn't have to be the case, but in 1993 Congress scrapped the Super Collider in Dallas, the US gave up the desire to lead in particle physics.

Congrats to both Fermilab and CERN for coming so close to detecting the Higgs boson!
