While strong supporting evidence for the particle physics theory of Quantum Chromodynamics (QCD) has been found in high energy collisions in experimental tests using perturbativetreatments because of its asymptotic freedom
behavior, the perturbative procedures have proven problematic for low-energy QCD, since the running coupling constant goes beyond 1.
A QCD property called Asymptotic Freedom
(see , p.
Among the areas they consider are breaking the symmetry, towards the standard model, renormalization, asymptotic freedom
, quark confinement and strings, the lattice, confrontation with experiments, and supersymmetry and supergravity.
Before the researchers came up with the concept of asymptotic freedom
, any relationship among the plethora of new particles observed during atom-smashing experiments remained hidden.
4 The Strong Coupling Constant and Asymptotic Freedom
Exploring how natural scientists have integrated notions of human free will into their models of the world, he ponders such matters as the age of neuroscience and the end of freedom; complexity, spontaneity, and social behaviors in biological evolution; freedom and the emergence of culture; forms of freedom, as-if freedom, and asymptotic freedom
as a challenge to neurophilosophy; a speech to the scientifically cultured despisers of religion; and freedom and transcendence.
