  • Here's how physicists calculate g-2, the value that will determine whether the muon is giving us a sign of new physics. (
  • Now, physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have identified a method by which instabilities can be tamed and heat can be prevented from leaking from the plasma, giving scientists a better grasp on how to optimize conditions for fusion in devices known as tokamaks. (
  • Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), in collaboration with researchers in South Korea and Germany, have developed a theoretical framework for improving the stability and intensity of particle accelerator beams. (
  • Following the convention of particle physicists, the term elementary particles is applied to those particles that are, according to current understanding, presumed to be indivisible and not composed of other particles. (
  • The word atom, after the Greek word atomos meaning "indivisible", has since then denoted the smallest particle of a chemical element, but physicists soon discovered that atoms are not, in fact, the fundamental particles of nature, but are conglomerates of even smaller particles, such as the electron. (
  • On 4 July 2012, physicists with the Large Hadron Collider at CERN announced they had found a new particle that behaves similarly to what is expected from the Higgs boson. (

  • The plasma wakefield acceleration (PWFA) technique is regarded as a highly promising route to the next generation of particle accelerators. (
  • This is no easy task, as only large-scale particle accelerators, such as those at DESY, CERN or SLAC, are currently capable of producing the driver pulses needed to generate the wakefield. (
  • The new findings will facilitate further investigation of the PWFA concept as a basis for the development of compact, next-generation particle accelerators. (
  • It is also called high energy physics, because many elementary particles do not occur under normal circumstances in nature , but can be created and detected during energetic collisions of other particles, as is done in particle accelerators . (

  • Furthermore, we use these and other methods to study the phenomenology of particle physics for use in predictions for particle accelerators. (
  • Top boffins at international science alliance CERN have decided to postpone a planned upgrade and keep the Large Hadron Collider - arse-kickingest particle-punisher and largest machine of any kind built by the human race - running at current power levels to the end of 2012. (
  • International boffins are vying with one another in a race to topsy-turvinate the world of physics this week, with a flurry of results due in imminently from radical fabric-of-time-and-space-rending experiments at the Large Hadron Collider - most brutally powerful particle-pummeller ever assembled by the human race. (
  • With all the current interest in particle physics and the Large Hadron Collider - the massive European particle accelerator due to begin operation this month - Peasley's Particle Zoo seems poised to be a smash hit. (
  • This is a very exciting time to be working on Particle Physics, since we sit at the threshold of new discoveries likely to be driven by experiments at the Large Hadron Collider. (
  • The grants are expected to cover the full range of particle physics research, including work based on proton-proton collisions at the Large Hadron Collider at CERN, the study of neutrinos, the search for dark matter and dark energy, the advance of particle accelerator and detector technologies, and particle physics theory. (
  • The particle was confirmed using the Large Hadron Collider - the highest-energy particle collider ever made, built by the European Organisation for Nuclear Research (CERN) in 2012. (

  • The possible existence of several unknown particles is also good news for researchers who explore new physics, for example, at the Particle Accelerator LHC at the research center CERN in Switzerland, where large experiments chase signals and evidence of unknown particles. (
  • The Weizmann Institute's Prof. Eilam Gross is currently the ATLAS Higgs physics group convener. (
  • If the model holds all the way to 1015 GeV, where the strong and electroweak interactions appear to unify, particles with truly titanic energies act on the Higgs and give it a comparably high mass. (
  • Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.g. to the newest "known" particle, the Higgs boson, or even to the oldest known force field, gravity. (
  • Members of the ATLAS and CMS experiments who are leading the search announced the observation of a new particle "consistent with the Higgs" at a very high level of confidence. (
  • The discovery of the Higgs boson 'God particle' was widely considered the biggest scientific breakthrough of modern day - so much so it won this year's Nobel Prize for Physics - but not everyone was quite so impressed. (
  • The Higgs boson's role is to give the particles that make up atoms their mass. (
  • Professor Hawking also had a more personal reason to lament the discovery, which earned Edinburgh scientist Professor Peter Higgs a £776,000 share of the Nobel Prize in Physics. (
  • I had a bet with Gordon Kane of Michigan University that the Higgs particle wouldn't be found,' he said. (
  • On the ATLAS experiment, we are searching for new massive particles that decay to a pair of particles, for example, two quark jets, two Higgs or two J/ψ particles. (
  • Specifically, we are searching for excited quarks, quantum black holes and additional bosons that can decay to two jets, gravitons that can decay to two Higgs particles, and hidden supersymmetric particles that can decay to two J/ψ particles (or other onia). (
  • In particular, we are measuring the CP properties of the Higgs boson and the fraction of Higgs particles that decay to taus. (
  • Graphic of a transverse section through a detector showing one of the numerous particle collision events recorded during the search for the Higgs boson. (
  • As soon as they have "re-discovered" the known Standard Model particles, a necessary precursor to looking for new physics, the LHC experiments will start the systematic search for the Higgs boson. (

  • The Higgs fits in with the so-called Standard Model-the mainstream theory of all the fundamental particles that make up matter and the forces that govern them. (
  • She is among researchers worldwide who participated in CMS experiments to search for the Higgs boson, a subatomic particle that could help explain why objects have mass. (
  • Iashvili is one of two CMS scientists in charge of jet energy scale calibration, a process that is critical to the CMS project's ability to identify different Higgs and other particles. (
