It ’s a find that ’s been decennary in the making , butwe have it on ripe authoritythat 2012 will be the yr physicists either confirm or refute the existence of the Higgs boson — the “ God particle , ” credited with giving mess to elementary particles .
This is the year the Large Hadron Collider notice out the Sojourner Truth about the Higgs boson
But make no mistake — there ’s more mystery and misconception smother the Higgs than the dubiousness of whether or not it exists . Here , symmetry magazine’sKathryn Grimdivulges some little - screw fact about the perplexing particle .
10 . Peter Higgs ’ best - cognize theme on the new particle was initially rejected
But this was a grace in disguise , since it leave Higgs to impart a paragraph introducing the now - famous Higgs particle . In 1964 , Higgs wrote two papers , each just two pages long , on what is now known as the Higgs field . The daybook Physics Letters accepted the first but sent the 2nd back . Yoichiro Nambu , a highly regarded physicist who had brush up the second paper , intimate Higgs add a section explaining his theory ’s physical implications . Higgs summate a paragraph call that an excitation of the theatre , like a wave in the ocean , would return a new molecule . He then resign the revise report to the vie journal Physical Review Letters , which published it .
9 . The scientific discipline minister for the United Kingdom once hold up a national competition to find the sound Higgs explanation
According to the Higgs model , elementary particle gain mass by interact with an unseeable , ubiquitous airfield . The more a subatomic particle interacts with the Higgs champaign , the more mass it will have . Scientists had such difficultness explain the Higgs field to the British government that in 1993 , UK Science Minister William Waldegrave challenged them to broadcast him their full one - varlet descriptions . Waldegrave handed out Champagne-Ardenne to the winners , who included physicist David Miller of University College London . Miller equate the Higgs field to a crowd of political political party actor circulate evenly through a elbow room . An anonymous person could move through the crowd unhampered . However , then Prime Minister Margaret Thatcher would attract a lot of attention : Party workers would clump around her , slowing her down , give her metaphorical “ muckle . ” originative types have since swap the fiber in the metaphor for Albert Einstein mobbed by fellow scientists or pop stars swarmed by paparazzi .

8 . The Higgs mechanics explains only a small fraction of the spate in the universe
Most popular science article give the Higgs model broad credit for loan mass to everything in the macrocosm . However , the Higgs theatre of operations give flock only to elementary particles such as quarks and electrons . Most of the visible universe is made of composite particles such as protons and neutron , which contain quark . Just as a loaf of raisin bread press more than the sum of its raisins , protons and neutrons get their quite a little from more than just the quarks inside them . The strong nuclear force that holds those quarks together does most of the mass - gift work . [ Raisin breadvia ]
7 . Higgs was not the only physicist who contributed to the melodic theme of how to give particle mass
At least a dozen theorists act some part in develop the theoretical fabric that led to the Higgs subatomic particle . In 2010 , the American Physical Society grant the J.J. Sakurai Prize to six physicists who had published papers on the issue in 1964 . But other idealogue came up with similar ideas , and earlier publication helped pave the way . The size of this crowd may trouble a certain Swedish commission , as the yearly Nobel Prize for physics can be awarded to three exist scientists at most . [ Physicists picturesvia APS ]
6 . The term “ boson ” comes from the name of Indian physicist and mathematician Satyendra Nath Bose
Particles come up in two variety show : bosons and fermions . The Higgs particle falls into the class of boson , named for a physicist well known for his collaborationism in the 1920s with Albert Einstein . Some of the pair ’s work leave in the innovation of Bose - Einstein statistics , a way to describe the doings of a class of particles that now deal Bose ’s name . Two bosons with very belongings can be in the same place at the same time , but two fermion can not . This is why photons , which are bosons , can travel together in concentrated laser beam . But electrons , which are fermion , must stay out from each other , which explains why electrons must reside in separate orbits in molecule . Bose never received a doctorate , nor was he awarded a Nobel Prize for his work , though the Nobel commission spot other scientists for enquiry relate to the concepts he developed .
5 . The nickname “ God subatomic particle ” originated from a book by Nobel laureate Leon Lederman
Physicist Leon Lederman unwittingly gave the Higgs boson what may be its most - dislike word form with the claim of his book , The God Particle . Lederman like to joke that he in reality want to call the Higgs boson the “ darned speck ” because it ’s so darned difficult to find . The nickname makes for attention - grabbing headlines , but it also makes most particle physicists cringe .
4 . received particle hypothesis will be incomplete even if the Higgs molecule is distinguish
The Higgs boson is the last undiscovered particle predicted by the Standard Model , a beautiful numerical fabric physicists apply to draw the smallest bits of matter and how they interact . observational results have time and again validated the model ’s other forecasting . But finding the Higgs boson would not end the Word on subatomic particle physical science . While the Standard Model accounts for primal forces such as electromagnetism and the strong nuclear force , it can not make common sense of soberness , which is disproportionately infirm compare to the other force . One potential explanation is that we experience only a fraction of the force of soberness because most of it acts in secret extra property .
3 . If the Higgs speck be , it may have relatives
Many theoriser have tried to explain the have a go at it particle and their masses without a Higgs boson , but no one has yet come up with a successful model . In fact , a popular theory known as supersymmetry bode at least five Higgs particles , and others predict many more . It is up to experiments at the Large Hadron Collider in Europe and at the Tevatron collider in the United States - – where experiments have conclude , but data are still being analyze – - to discover whether the Higgs boson exists and , if so , whether it is the particle we anticipate .

2 . Scientists may have first glimpsed the Higgs boson more than a decade ago
In 2000 , CERN ’s flagship throttle valve , the Large Electron Positron Collider , was scheduled to close after 11 eld of successful functioning when something funny hap . The LEP experimentation begin to detect signs of something that looked rather like the Higgs molecule with a mass around 115 GeV / c2 , about the mass of an iodine atom . Excited scientists convinced CERN management to keep LEP running for six weeks beyond the original shut out - down date to see if the notice would rise more convincing with extra datum . During the auto ’s stay of instruction execution , even more candidate Higgs outcome appeared . Physicists requested a 2nd reference to see if their observation might flower into a discovery , but the machine was dismantled to make way for a gamy - energy Higgs hunter , the LHC . The latest LHC results , made public in December 2011 , point that the Higgs molecule , if it survive , must have a mass between 115 - 130 GeV / c2 . The ATLAS and CMS experiment account intriguing breath of a Higgs boson with a passel in the part of 124 - 126 GeV. [ LEPvia ]
1 . find the new particle would be only the beginning
Just because something face like the Higgs particle does not stand for it is the Higgs particle . If physicist do discover a newfangled molecule , they will need to measure its legion properties before they can determine whether it is the Higgs boson described by the Standard Model of mote purgative . hypothesis prognosticate in great detail how a Standard Model Higgs corpuscle would interact with other mote . Only after cautiously measuring and examine these interaction – like a life scientist test the hereditary makeup of a unexampled plant species – would scientist be sure that they had indeed found the Standard Model Higgs boson . A new particle that did not do as wait would give physicists a whole unexampled exercise set of mysteries to explore . [ Higgs collisionvia ]
