Physicists deny rumours that 'God particle' has been discovered at US lab

Scientists have been forced to deny rumours that a US laboratory has discovered the mysterious Higgs Boson particle.
科學家們已被迫否認傳聞,指出美國實驗室已發現神秘的希格斯玻色子粒子。
A blog published by a physicist had hinted that the Fermi National Accelerator Laboratory (Fermilab) in Illinois had beaten the Large Hadron Collider (LHC) by being the first to find the so-called ‘God Particle'.
一個物理學家發表的博客曾暗示,在伊利諾伊州的費米國家加速器實驗室(費米實驗室)已打敗大型強子對撞機(LHC),率先發現所謂的'上帝粒子'。
Tommaso Dorigo, an experimental particle physicist who works on an experiment at Fermilab, wrote: ‘It reached my ear from two different, possibly independent sources, that an experiment at the Tevatron (part of Fermilab) is about to release some evidence of a light Higgs boson signal.’
實驗粒子物理學家托馬索里戈,他工作在費米實驗室的一個實驗說:'兩個不同的獨立消息來源到達我的耳朵,一個在Tevatron的實驗(費米實驗室的一部分)即將公佈,會有一些光希格斯玻色子的證據訊號。
He adds: 'Some say a three-sigma effect, others do not make explicit claims but talk of a unexpected result.'
他補充:'有些人說一3-西格瑪的影響,其他人不作明確的聲稱但談及一個意想不到的結果。

His comments sparked wild speculation that the US lab was about to trump the far bigger LHC at Cern.
他的言論引發胡亂猜測,美國的實驗室要勝過大得多在CERN的 LHC。
But today a spokeswoman for Fermilab today denied the rumours and said there was ‘no factual basis’ for Professor Dorigo’s comments.
但今天費米實驗室的一位發言人今天否認傳言,和說教授里戈的評論'沒有事實依據'。
Rhianna Wisniewski said if its researchers had found the elusive particle, they would have announced it.
雷亞安娜威斯妮斯基說,如果它的研究人員已經到那難以捉摸的粒子,他們會已經宣布它。
And later in the same blog post that trumpets the discovery of the Higgs Boson, Dorigo admits that he believes physics needs far more publicity.
及之後在同一吹發現希格斯玻色子的博客帖文,多里戈承認他相信物理學需要遠多的宣傳。
He said: ' It does a lot of good to particle physics, in my very humble, but not quite uninformed, opinion. I have made this point other times, and will not repeat it here.
他說:'它做了很多很好的粒子物理學,以我很謙虛但並不完全無知的意見;我已在其它多次表達這點,和不再在這裡重複了。
'Suffices to say that, in a nutshell, keeping particle physics in the press with hints of possible discoveries that later die out is more important than speaking loud and clear once in ten years, when a groundbreaking discovery is actually really made, and keeping silent the rest of the time.'
The theoretical Higgs boson is supposed to impart mass to other and is seen as the key to proving the standard model particle physics.
The Standard Model has gaps that only the existence of the Higgs Bosons would fill.
The Large Hadron Collider was designed to find the Higgs Boson by colliding beams of protons at close to the speed of light.

謠言:大型強子對撞機的對手萬億電子已'發現希格斯玻色子'
Large Hadron Collider rival Tevatron 'has found Higgs boson', say rumours

Rumours are emerging from the rival to the Large Hadron Collider that the Higgs boson, or so-called "God particle", has been found.
來自大型強子對撞機對手的謠言出現,希格斯玻色子,或所謂的“上帝粒子”,已被發現。

Tommaso Dorigo, a physicist at the University of Padua, has said in his blog that there has been talk coming out of the Fermi National Accelerator Laboratory in Batavia, Illinois, that the Higgs has been discovered.

• Higgs boson discovery rumours false, say Tevatron scientists

The Tevatron, the huge particle accelerator at Fermi - the most powerful in the world after the LHC - is expected to be retired when the CERN accelerator becomes fully operational, but may have struck a final blow before it becomes obsolete.

If one form of the rumour is to be believed - and Prof Dorigo is extremely circumspect about it - then it is a "three-sigma" signature, meaning that there is a statistical likelihood of 99.7 per cent that it is correct. But, of course, that is only if the rumour is to be believed.

In the post, titled "Rumors about a light Higgs", Prof Dorigo said: "It reached my ear, from two different, possibly independent sources, that an experiment at the Tevatron is about to release some evidence of a light Higgs boson signal.

"Some say a three-sigma effect, others do not make explicit claims but talk of a unexpected result."

While media attention has been focusing on the LHC, the Tevatron has been quietly plugging away in the search for Higgs. In the 27 years since it was first completed (it has been regularly upgraded since then) it has discovered a quark and observed four different baryons. While it has not been able to pinpoint the elusive Higgs, it has narrowed the search, reducing the window of possible masses where it might be found.

Last year, Fermi physicists said they expected to have enough data to find or rule out the Higgs by early next year, and gave themselves a fifty-fifty chance of finding it before the end of 2010.

The Higgs boson is the last of the particles posited by the standard model of particle physics still to be found. It is said to explain why other particles have mass, and its discovery would confirm the standard model. If its existence is ruled out altogether, then other, previously less popular theories will have to be examined.

New Scientist suggests that more may be known this month, when scientists present their findings at the International Conference on High Energy Physics (ICHEP), which opens in Paris on 22 July.
