(PhysOrg.com) — Around midnight this night CERN’s Large Hadron Collider set a new world record for beam intensity at a hadron collider when it collided beams with a luminosity of 4.67 x 1032cm-2s-1. This exceeds the previous world record of 4.024 x 1032cm-2s-1, which was set by the US Fermi National Accelerator Laboratory’s Tevatron collider in 2010, and marks an important milestone in LHC commissioning.

Mystery signal at Fermilab hints at ‘technicolour’ force – physics-math – 07 April 2011 – New Scientist

The physics world is buzzing with news of an unexpected sighting at Fermilab’s Tevatron collider in Illinois – a glimpse of an unidentified particle that, should it prove to be real, will radically alter physicists’ prevailing ideas about how nature works and how particles get their mass.

The candidate particle may not belong to the standard model of particle physics, physicists’ best theory for how particles and forces interact. Instead, some say it might be the first hint of a new force of nature, called technicolour, which would resolve some problems with the standard model but would leave others unanswered.

The observation was made by Fermilab’s CDF experiment, which smashes together protons and antiprotons 2 million times every second. The data, collected over a span of eight years, looks at collisions that produce a W boson, the carrier of the weak nuclear force, and a pair of jets of subatomic particles called quarks.

Physicists predicted that the number of these events – producing a W boson and a pair of jets – would fall off as the mass of the jet pair increased. But the CDF data showed something strange (see graph): a bump in the number of events when the mass of the jet pair was about 145 GeV.

LHC First Beam on 
10 September 2008 

Primeira experiência do LHC

Geneva, 10 de Setembro de 2008. O primeiro teste com um feixe de milhões de protões no acelerador LHC (Large Hadron Collider) do Laboratório Europeu de Física de Partículas (CERN) foi bem sucedido, percorrendo os 27 quilómetros às 10h28min desta manhã. Este evento histórico marca um momento chave na transição, com mais de duas décadas de preparação, para uma nova era de descobertas científicas.

First beam in the LHC – accelerating science

Geneva, 10 September 2008. The first beam test, with millions of protons, in the Large Hadron Collider (LHC) at CERN was successfully. The beam covered a distance around the full 27 kilometres at 10h28 this morning. This historic event marks a key moment in the transition to a new era of scientific discovery.
