Title: From Sakata model to Goldberg-Ne'eman quarks and Nambu QCD phenomenology and "right" and "wrong" experiments.

Abstract

The basic theoretical milestones were the Sakata SU(3) symmetry, the Goldberg-Ne'eman composite model with SU(3) triplets having baryon number (1/3) and the Nambu color gauge Lagrangian. The transition was led in right and wrong directions by experiments interpreted by phenomenology. A 'good' experiment on {bar p}p annihilation at rest showed that the Sakata model predictions disagreed with experiment. A 'bad' experiment prevented the use of the Goldberg-Ne'eman triplet model to predict the existence and masses of the of the {Xi} and {Omega}{sup -}. More 'good' experiments revealed the existence and mass of the {Xi}* and the {Omega}{sup -} and the absence of positive strangeness baryon resonances, thus confirming the 'tenfold way'. Further 'good experiments' revealed the existence of the vector meson nonet, SU(3) breaking with singlet-octet mixing and the suppression of the {phi} {yields} {rho} {pi} decay. These led to the quark triplet model. The paradox of peculiar statistics then arose as the {Delta}{sup ++} and {Omega}{sup -} contained three identical spin-1/2 fermions coupled symmetrically to spin (3/2). This led to color and the Nambu QCD. The book 'Lie Groups for Pedestrians' used the Sakata model with the name 'sakaton' for the {Lambda} triplet to teach the algebra of SU(3)more » to particle physicists in the U.S. and Europe who knew no group theory. The Sakata model had a renaissance in hypernuclear physics in the 1970's.« less

  • If QCD is renormalized by minimal substraction (MS), at higher orders, the strong coupling constant {alpha}{sub s} and the quark masses m{sub q} exhibit discontinuities at the flavor thresholds, which are controlled by so-called decoupling constants, {zeta}{sub g} and {zeta}{sub m}, respectively. Adopting the modified MS (MS) scheme, we derive simple formulas which reduce the calculation of {zeta}{sub g} and {zeta}{sub m} to the solution of vacuum integrals. This allows us to evaluate {zeta}{sub g} and {zeta}{sub m} through three loops. We also establish low-energy theorems, valid to all orders, which relate the effective couplings of the Higgs boson tomore » gluons and light quarks, due to the virtual presence of a heavy quark h, to the logarithmic derivatives w.r.t. m{sub h} of {zeta}{sub g} and {zeta}{sub m}, respectively. We also consider the effective QCD interaction of a CP-odd Higgs boson and verify the Adler-Bardeen nonrenormalization theorem at three loops.« less
  • We report on a lattice-QCD calculation of the B to pi l nu form factor with domain-wall light quarks and relativistic b-quarks using the 2 + 1 flavor domain-wall fermion and Iwasaki gauge-field ensembles generated by the RBC and UKQCD Collaborations. We present initial results obtained from the coarser (a ~ 0.11 fm) 24^3 lattices and some of the finer (a ~ 0.086 fm) 32^3 lattices.
  • Applications of the Standard Model to the description of physics at hadron colliders are discussed. Particular attention is paid to the use of jets to characterize this physics. The issue of identifying physics beyond the Standard Model is also discussed. 59 refs., 6 figs., 4 tabs.
  • Heavy quark quantities are useful for testing lattice techniques against well known experimental results, as well as for testing the StandardModel (SM), and searching for physics beyond the SM. I review the results of recent lattice calculations relevant for this program including those of B and D decay constants and semileptonic decay form factors, and neutral B mixing. The impact of future improvements of lattice results on the clarification of the origin of several disagreements between theory and experiment which are starting to show up are briefly discussed.
