Some top measurements from CERN's Large Hadron Collider | Life & Physics
by Jon Butterworth from on (#KJZ4)
New and improved measurements of the heaviest quark. Also, in what sense do protons get bigger as they go faster, and how do we know?
It has been an interesting summer for particle physics. The first results from the current higher-energy collisions at the Large Hadron Collider (LHC) have seen the light of day. If you have been following the experiment you may know that the energy of the proton beams has been increased from 4000 GeV to 6500 GeV (a GeV is a billion electronVolts), giving a collision energy of 13000 GeV. But also interesting have been some of the refined results which are still being produced using the earlier data, recorded between 2010 and 2012.
