Exempel på hur man kan använda GLUON i en mening

• They are minute random fluctuations in the values of the fields which represent elementary particles, such as electric and magnetic fields which represent the electromagnetic force carried by photons, W and Z fields which carry the weak force, and gluon fields which carry the strong force.
• This justifies the introduction of transversely and longitudinally-polarized photons, and of the related concept of transverse and longitudinal structure functions, when considering these virtual states as effective probes of the internal quark and gluon contents of the hadrons.
• that in a meson not only the particles (quarks and antiquarks), but also the "fluxtubes" of the gluon fields are important.
• The term inflaton follows the typical style of other quantum particles’ names – such as photon, gluon, boson, and fermion – deriving from the word inflation.
• In lattice QCD, fields representing quarks are defined at lattice sites (which leads to fermion doubling), while the gluon fields are defined on the links connecting neighboring sites.
• Jet (particle physics), a narrow cone of hadrons and other particles produced by the hadronization of a quark or gluon.
• Additionally, studying gluon decay widths in light quarkonia can help determine the quantum chromodynamics (QCD) scale parameter.
• In the wake of the September 11 attacks, Larsen began a large-scale C- print series which melds her photographic oeuvre with expressive hi-color gluon paintings.
• Then around T = 150 MeV there is a crossover to the quark gluon plasma: thermal fluctuations break up the pions, and we find a gas of quarks, antiquarks, and gluons, as well as lighter particles such as photons, electrons, positrons, etc.
• Instead of considering the ghost propagator, he computed the lowest eigenvalue of the Faddeev–Popov operator as a perturbative series in the gluon field.
• The probability of creating a certain set of jets is described by the jet production cross section, which is an average of elementary perturbative QCD quark, antiquark, and gluon processes, weighted by the parton distribution functions.
• Despite the simple structure of the tree-level perturbative quantum field theory description of the collision and decay processes in an event, the observed high-energy process usually contains significant amount of modifications, like photon and gluon bremsstrahlung or loop diagram corrections, that usually are too complex to be easily evaluated in real calculations directly on the diagrammatic level.
• Similarly, a gluon parton at one scale can resolve into a superposition of a gluon parton state, a gluon parton and quark-antiquark partons state and other multiparton states.
• When gluon recombination balances gluon splitting, the density of gluons saturate, producing new and universal properties of hadronic matter.
• Such particles include the gluon (carrier of the strong force), the photons that make up light (hence carrier of electromagnetic force), and the hypothetical gravitons (which are the presumptive field particles associated with gravity; however, an understanding of the graviton, if any exist, requires an as-yet unavailable theory of quantum gravity).
• In these interactions, the energy of the partons is reduced through collisional energy loss and medium-induced gluon radiation, the latter being the dominant mechanism in a QGP.
• Such particles include the gluon (carrier of the strong force), the photons that make up light (hence carrier of electromagnetic force), and the hypothetical gravitons (which are the presumptive field particles associated with gravity; however, an understanding of the graviton, if it exists, requires an as-yet unavailable theory of quantum gravity).
• ; Gluon fusion : If the collided particles are hadrons such as the proton or antiproton as is the case in the LHC and Tevatron then it is most likely that two of the gluons binding the hadron together collide.
• Yield equilibration of strangeness yield in QGP is only possible due to a new process, gluon fusion, as shown by Rafelski and Müller.
• With colleagues, he has recently re-emphasized the role of neutralino dark matter in the context of cosmic ray data, as well as the importance of connecting dark matter and the LHC - in particular focusing on light gluinos and light neutralinos (the putative superparteners of the gluon and W boson respectively) that arise in supergravity and string theory motivated models.
