Exempel på hur man kan använda BOSON i en mening

• From left, clockwise: the passenger cruise ship Costa Concordia lies capsized after the Costa Concordia disaster; damage to Casino Pier in Seaside Heights, New Jersey as a result of Hurricane Sandy; people gather at a Mayan temple to commemorate the end of 13th bʼakʼtun in the Mayan calendar on December 21, when it was predicted a doomsday event would occur; NASA's Curiosity Rover lands on the surface of Mars; the Sandy Hook Elementary School shooting caused turmoil across the United States; K-pop artist Psy performs his hit single "Gangnam Style", which became a cultural phenomenon in 2012; the elementary particle, the Higgs boson, dubbed "The God Particle", is discovered by CERN and revolutionizes quantum physics; the 2012 Summer Olympics are held in London, United Kingdom.
• Since then, proof of the top quark (1995), the tau neutrino (2000), and the Higgs boson (2012) have added further credence to the Standard Model.
• On July 2, 2012, scientists of the CDF and DØ collider experiment teams at Fermilab announced the findings from the analysis of around 500 trillion collisions produced from the Tevatron collider since 2001, and found that the existence of the suspected Higgs boson was highly likely with a confidence of 99.
• Weinberg's model, now known as the electroweak unification theory, had the same symmetry structure as that proposed by Glashow in 1961: both included the then-unknown weak interaction mechanism between leptons, known as neutral current and mediated by the Z boson.
• The bottom quark is also notable because it is a product in almost all top quark decays, and is a frequent decay product of the Higgs boson.
• The goal of the CMS experiment is to investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.
• Neutral current, a class of physics interaction where the mediating boson is neutral, especially for neutrino experiments.
• An example is the "annihilation" of a high-energy electron antineutrino with an electron to produce a W boson.
• The LHC's goal is to allow physicists to test the predictions of different theories of particle physics, including measuring the properties of the Higgs boson, searching for the large family of new particles predicted by supersymmetric theories, and studying other unresolved questions in particle physics.
• In particle physics, a gauge boson is a bosonic elementary particle that acts as the force carrier for elementary fermions.
• Two are short range: the strong interaction mediated by mesons and the weak interaction mediated by the weak boson; two are long range: electromagnetism mediated by the photon and gravity hypothesized to be mediated by the graviton.
• In the MSSM, the Higgs boson has a fermionic superpartner, the Higgsino, that has the same mass as it would if supersymmetry were an exact symmetry.
• Three papers are published by Robert Brout and François Englert, Peter Higgs, and Gerald Guralnik, Dick Hagen, and Tom Kibble, predicting the Higgs boson and Higgs mechanism (or Englert–Brout–Higgs–Guralnik–Hagen–Kibble mechanism) which provides the means by which gauge bosons can acquire non-zero masses in the process of spontaneous symmetry breaking.
• In fluids, the phonon is longitudinal and it is the Goldstone boson of the spontaneously broken Galilean symmetry.
• In particle physics, majorons (named after Ettore Majorana) are a hypothetical type of Goldstone boson that are conjectured to mediate the neutrino mass violation of lepton number or B − L in certain high energy collisions such as.
• On 8 October 2013, following the discovery at CERN's Large Hadron Collider of a new particle that appeared to be the long-sought Higgs boson predicted by the theory, it was announced that Peter Higgs and François Englert had been awarded the 2013 Nobel Prize in Physics.
• A pseudovector boson is a vector boson that has even parity, whereas "regular" vector bosons have odd parity.
• In the Standard Model, quarks and leptons have "Yukawa couplings" to the Higgs boson which determine the masses of the particles.
• Between the hardback and paperback release of Knocking on Heaven's Door, the quest for the discovery of the Higgs boson was actually completed, a subject discussed in the book.
• More technically, the question is why the Higgs boson is so much lighter than the Planck mass (or the grand unification energy, or a heavy neutrino mass scale): one would expect that the large quantum contributions to the square of the Higgs boson mass would inevitably make the mass huge, comparable to the scale at which new physics appears unless there is an incredible fine-tuning cancellation between the quadratic radiative corrections and the bare mass.
