This plot, realized by Philip Gibbs, summarize the mass exclusion region of Higgs boson. Indeed, recently, the most important collaborations of the two great particle accelerators, Tevatron (who finished its activity) and LHC, presented their results at Eps-Hep 2011 conference.
Following plot, we can conclude that Higgs boson probably signed the end of Standard Model: it’s very difficult that it exists in the region between 114 GeV - 145 GeV (the signal in this region is very low), and if it will find in the region between 200 GeV - 300 GeV we have one of the first observation disagree Standard Model.

Stalking the RHIC via Google Earth FTW!
let’s see how many notes this gets. the last time I posted a Google Earth screencap of the Tevatron, the post had a tons of notes.

The Large Hadron Collider was completed in 2008, and is known as the largest and most complex particle accelerator ever made. Its primary function is to generate two beams of subatomic particles called ‘hadrons’ (protons or lead ions) and accelerate them in opposite directions at 99.9999991% the speed of light, then observe their collision. By doing this, scientists can learn a lot about the structure of the universe, as purposely colliding protons tells them about the internal structure of matter and the energy within it.
It is both the hottest place in the Solar System and colder than outer space. When the two beams of protons collide, they generate temperatures that are 100,000 times hotter than the core of the Sun. However, the ‘cryogenic distribution system’, which circulates superfluid helium around the accelerator ring, keeps the Hadron Collider at -271.3 degrees Celsius, which is colder than outer space. The machine is also known as the emptiest space in the Solar System, as the internal pressure inside the Hadron Collider is 0.000000000000010, ten times less than the pressure on the Moon.
The Large Hadron Collider will hopefully gives Scientists a new means of understanding the forces of nature. For decades, physicists have used the incomplete Standard Model of particle physics. Only experiments using the Hadron Collider can push knowledge forward.
