Because only one super collider is likely to be built, China's momentum puts it firmly in the driving seat. But on a microscopic scale, it’s huge heavier than some entire molecules. On a human scale, that’s a tiny number less than a billionth of a billionth of a gram. China would like to build its electron-positron collider in the meantime, unaided by international funding if needs be, and follow it up as fast as technologically possible with the super proton collider. The Higgs has a mass energy of 126 billion electron volts. But China hopes that it would also be a stepping stone to a next-generation collider - a super proton-proton collider - in the same tunnel.Įuropean and US teams have both shown interest in building their own super collider (see Nature503, 177 2013 ), but the huge amount of research needed before such a machine could be built means that the earliest date either can aim for is 2035. Such collisions would enable researchers to study known particles, such as the Higgs boson, with greater precision than is possible at a protonproton collider such as the LHC. 33 It is the only particle that remains massive even at very high energies. Its mass has been determined to be 125.35 0.15 GeV/c2. Physicists say that the proposed US$3-billion machine is within technological grasp and is considered conservative in scope and cost. In the Standard Model, the Higgs boson is a massive scalar boson whose mass must be found experimentally.
Collisions of these fundamental particles would allow the Higgs boson to be studied with greater precision than at the much smaller Large Hadron Collider (LHC) at CERN, Europe's particle-physics laboratory near Geneva, Switzerland. Scientists at the Institute of High Energy Physics (IHEP) in Beijing, working with international collaborators, are planning to build a 'Higgs factory' by 2028 - a 52-kilometre underground ring that would smash together electrons and positrons. If we don’t see something beyond the Higgs. If we see something beyond the Higgs: spectacular, says Arkani Hamed. But a proposal by China that is quietly gathering momentum has raised the possibility that the country could soon position itself at the forefront of particle physics. Most theoretical physicists, including Arkani-Hamed, believe there has to be something beyond the Higgseither supersymmetric particles or other new particles that the LHC may discover as soon as the end of this year.

#Higgs boson supercollider upgrade
Quanta Magazine, 14 June 2016 The need to upgrade CMS comes from a recent upgrade of the supercollider itself. 2021 In 2012, the world’s biggest supercollider discovered the Higgs boson, completing the Standard Model of particle physics. Recent Examples on the Web The new circular supercollider will sit next to its predecessor at CERN in Switzerland, but will be nearly three times its size, with a circumference of 100 kilometers.Īndrea Willige, Forbes, 18 Mar.
