힉스 보존 입자를 찾았다. 만물의 질량이며 존재하지 않았던 입자를 찾은 것 ! 이야말로 경사이다 ! 축배를 들자 건배 ! 이번 발견은 내 생에 보게 될 물리의 가장 큰 업적이지 않을까 싶다. 앞으로 규모가 작은 연구들과 발견들이 무수히 많겠지만, 이러한 쾌감은 없을 것이라는 아쉬움을 표현하는 학자들도 있더라. 아무튼 신난다.

지난 해 겨울에 블로그에 힉스 입자에 대해 포스팅 한 것이 있다. (higgs boson 힉스 보존 입자 존재하는가, 증명은 시간문제인가) 시간문제였던 것이다 ! 이전 포스팅에서도 언급 된 LHC large hadron collider 거대 강입자 충돌기를 돌리고 돌리고 돌리어 자료를 모으고 모으고 모은 결과 힉스 입자의 존재가 증명되었다. 

물리학의 굉장한 획을 긋는 이벤트. 이렇게 짙고 거대한 획을 그은 현재로써, 앞으로 해야 할 새로운 과제는 무엇이 있을까. 


Cern 은 이제 dark matter 암흑 입자에 관심을 두기로 한다는 Telegraph 의 기사

After the Higgs boson, scientists at Cern aim for super LHC turn their sights on dark matter

The Large Hadron Collider is to be given a £1.2 billion upgrade as scientists at the Cern laboratory turn their attention to finding dark matter.

Physicists believe dark matter is what holds the universe together. Yet while it makes up 84 per cent of all matter, and is all around us, it has never been seen as it does not produce or reflect light.

Now scientists hope that a 10-fold boost to the power of the beams of particles being smashed together inside Cern’s 17-mile tunnels will allow them to create and detect dark matter.

Plans approved by the governing body of Cern will involve its £6.6billion particle smasher being closed down for at least two years.

The move comes after Cern physicists last week announced the discovery of the particle they believe could be the elusive Higgs boson, thought to be responsible for giving other particles mass.

Although there is still much work to be done on the Higgs boson, the milestone has left many at Cern worried that the public and funders will feel their work is now complete. But other experiments will continue until the end of this year, when the LHC will close for 20 months for repairs.

The LHC works by smashing protons – the particles found at the heart of all atoms – together to produce temperatures of more than four trillion degrees Celsius, 250,000 times hotter than the centre of the sun. Detectors around the ring identify the debris thrown out from these collisions. Scientists hope that the 2020 upgrade, dubbed “super-LHC”, will let them see some of the rarest particles of all.

Phil Allport of the University of Liverpool, UK lead for one of Cern’s detectors, ATLAS, said: “It will allow us to greatly extend the reach to search for new physics as well as make some very precise measurements, for example, to potentially address the nature of dark matter.

“Essentially we will be looking for a major imbalance in the particles being emitted after a collision."
