科学家寻找人称上帝粒子的希格斯粒子



Some 200 scientists and other staffs gathered in Fermi Lab at 2 O’clock in the morning, to watch the announcement from Geneva.

Many of them have strong connections to the CERN experiment, using the atom-smashing Large Hadron Collider or LHC to locate the Higgs Boson, including the head of the CMS Group, Patricia McBride:

“The techniques we, that are being used there were, were first tried out here. A lot of the people, did, did their training here in Fermi Lab.”

Scientists have spent hundreds of millions of dollars creating technologically advanced devices that can smash atoms together, and tens of thousands of hours of manpower pouring over the resulting data.

But they now believe they have found what looks like the sub-atomic particle known as the Higgs Boson.

“It’s one of our key missing links to our understanding of really how the universe is created.”

Fermi Lab staff scientist Robert Roser says the Higgs Boson is a particle that attracts other particles and explains how matter has mass. This gives clues to how planets and ultimately life is formed.

But he points out his colleagues at CERN were careful to say they found a Higgs like object, but not the Higgs Boson itself.

“It’s a subtle difference. So what they will do over the course of the next many years is to start to investigate all of its properties to see if it acts, if it smells, tastes and behaves the way they expect it to.”

Fermi Lab was home to the LHC’s predecessor, the Tevatron Accelerator which went off line late last year.

Roser says the final data produced by the Tevatron is consistent with CERN’s findings. He says it all leads up to dramatic change for scientists:

“The finding of this will change the way scientists view the world immediately and will change the way I go to work tomorrow. In terms of how it affects the general public, not so much.”

While it’s not clear yet where the finding will ultimately lead, McBride and Roser say the technology developed to find the Higgs Boson has already produced tangible results, such as the cloud-based digital storage now used by mobile phones and computers.

But Roser adds the real benefits are yet to come.

“So it’s not fairly necessary to ask me today what the practice benefit of the Higgs Boson is. I think we will know in the course of time what it is. But you know, that’s said mankind has always asked the question why and we are one step closer to understanding that.”

The next step, says Roser, is confirming without a scientific doubt that what they now believe is the Higgs Boson, actually is.
