Exempel på hur man kan använda MESON i en mening

• In a 1939 note to Nature, Bhabha argued the particle should be christened the "meson" in line with the word's Greek etymology, not "mesotron" as Anderson had proposed.
• According to the Standard Model of particle physics, a subatomic particle can be either a composite particle, which is composed of other particles (for example, a baryon, like a proton or a neutron, composed of three quarks; or a meson, composed of two quarks), or an elementary particle, which is not composed of other particles (for example, quarks; or electrons, muons, and tau particles, which are called leptons).
• These nearly pure states characteristic of the vector mesons are not at all evident in the pseudoscalar meson or scalar meson multiplets, and may be only slightly realized among the tensor meson and pseudovector meson multiplets.
• Salam's notable achievements include the Pati–Salam model, a Grand Unified Theory he proposed along with Jogesh Pati in 1974, magnetic photon, vector meson, work on supersymmetry and most importantly, electroweak theory, for which he was awarded the Nobel Prize.
• He was also influenced then by discussions with Léon Rosenfeld of the University of Liège, who was invited to Utrecht to give a colloquium in an effort to find a successor for Uhlenbeck and reported on the work he was then doing with Christian Møller on the meson theory of nuclear forces.
• Each meson has a corresponding antiparticle (antimeson) where quarks are replaced by their corresponding antiquarks and vice versa.
• Later, Yang worked on particle phenomenology; a well-known work was the Fermi–Yang model treating pion meson as a bound nucleon–anti-nucleon pair.
• In 1976, Ting was awarded the Nobel Prize in Physics, which he shared with Burton Richter of the Stanford Linear Accelerator Center, for the discovery of the J/ψ meson nuclear particle.
• that in a meson not only the particles (quarks and antiquarks), but also the "fluxtubes" of the gluon fields are important.
• He led the Stanford Linear Accelerator Center (SLAC) team which co-discovered the J/ψ meson in 1974, alongside the Brookhaven National Laboratory (BNL) team led by Samuel Ting for which they won Nobel Prize for Physics in 1976.
• For that reason the top quark does not hadronize, that is it never forms any meson or baryon, so the topness of a meson or a baryon is always zero.
• This hall houses the GlueX experiment, which is designed to map out the light unflavored meson spectrum in detail in the search for explicit gluonic excitations in mesons.
• Applied to a whole octave, the Dorian octave species was built upon two tetrachords (four-note segments) separated by a whole tone, running from the hypate meson to the nete diezeugmenon.
• Its large solid angle coverage (near hermetic), vertex location with precision on the order of 10 μm (provided by a silicon vertex detector), good pion–kaon separation at multi-GeV momenta (provided by a novel Cherenkov detector), and few-percent precision electromagnetic calorimetry (CsI(Tl) scintillating crystals) allow a list of other scientific searches apart from CP violation in the B meson system.
• Typically, every quark model meson comes in SU(3) flavor nonet: an octet and an associated flavor singlet.
• Hideki Yukawa was a Japanese theoretical physicist and the first Japanese Nobel laureate for his prediction of the pi meson, or pion.
• For example, the three quarks making up any baryon universally have three different color charges, and the two quarks making up any meson universally have opposite color charge.
• Since the late 1950s, the lightest scalar mesons were often interpreted within the framework of the linear sigma model, and many theorists still choose this interpretation of the scalar mesons as the chiral partners of the pseudoscalar meson multiplet.
• The dual theory contains a fundamental "meson" chiral superfield M which is color neutral but transforms as a bifundamental under the flavor symmetries.
• The structure of the pseudoscalar meson multiplet, and also the ground state baryon multiplets, led Gell-Mann (and Zweig, independently) to create the well known quark model.
