1. If a UV fixed point is asymptotically free.
2. Through the AdS / CFT correspondence it provides a holographic description of gauge theories which are asymptotically free.
3. The Standard Model is not asymptotically free, with the Landau pole a problem when considering the Higgs boson.
4. They also argued that in asymptotically free theories the dynamically generated masses never depend analytically on the coupling constants.
5. By contrast, a natural theory of electroweak symmetry breaking is an asymptotically free gauge theory with fermions as the only matter fields.
6. It's difficult to find asymptotically free in a sentence. 用asymptotically free造句挺難的
7. The quark gluon plasma is formed as protons and neutrons " melt " into their elementary constituents, quarks and gluons become asymptotically free.
8. In the 1990s, the idea emerged more clearly that walking is naturally described by asymptotically free gauge theories dominated in the infrared by an approximate fixed point.
9. In 1986 Appelquist, Karabali and Wijewardhana discussed the enhancement of fermion masses in an asymptotically free technicolor theory with a slowly running, or  walking, gauge coupling.
10. In 1981 Holdom suggested that, if the ? TC ( ? ) evolves to a nontrivial fixed point in the ultraviolet, with a large positive asymptotically free theory to enhance the technifermion condensate.
11. For standard QCD with three colors, as long as there are no more than 16 flavors of quark ( not counting the antiquarks separately ), antiscreening prevails and the theory is asymptotically free.
12. For sufficiently short distances or large exchanges of momentum ( which probe short-distance behavior, roughly because of the inverse relation between a quantum's momentum and De Broglie wavelength ), an asymptotically free theory is amenable to confinement.
13. They each earned a Ph . D . in physics from the Institute for Theoretical and Experimental Physics, Alexei with a thesis titled " Factorized scattering in asymptotically free two-dimensional models of quantum field theory " ( 1979 ).
14. Unlike the speculative proposal of ultraviolet fixed points, fixed points in the infrared are known to exist in asymptotically free theories, arising at two loops in the beta function providing that the fermion count " N " f is large enough.
15. The Standard Model of particle physics is perturbatively renormalizable, and so are its component theories ( quantum electrodynamics / asymptotically free " SU ( 2 ) " and " SU ( 3 ) " weak and strong color interactions are nonperturbatively well defined.
16. This interaction is asymptotically free at very high energies and becomes strong and confining as the energy decreases to the electroweak scale of 246 GeV . These strong forces spontaneously break the massless fermions'chiral symmetries, some of which are weakly gauged as part of the Standard Model.
