WebApr 16, 2024 · Now these charges are not quite conserved (because of quark mass differences, as we now know, and was suspected all along back then), so this SU(3) symmetry is violated, but current algebra relations helped quantify the violation in systematic ways--the genius of flavor SU(3) symmetry ("violated by the strong … WebAug 1, 2002 · Current Algebra: Quarks and What Else?

WebAn alternative is proposed to specific Lagrangian models of current algebra. In this alternative there are no explicit canonical fields, and operator products at the same point [say, ${j}_{\\ensuremath{\\mu}}(x){j}_{\\ensuremath{\\mu}}(x)$] have no meaning. Instead, it is assumed that scale invariance is a broken symmetry of strong interactions, as … WebCurrent quark mass . The approximate chiral symmetry of quantum chromodynamics, for example, allows one to define the ratio ... The scheme grouped together particles with isospin and strangeness using a unitary symmetry derived from current algebra, which we today recognise as part of the approximate chiral symmetry of QCD. This is a global ...

The heaviest top quark, having mass about two hundred times that of the proton, was found later (Fermilab, 1995). The direct observation of W and Z vector bosons was first made by UA1 and UA2 experiments at CERN (1983).

PCAC and current algebra also provide evidence for this pattern of SSB. Direct estimates of the chiral condensate also come from such analysis.
