Abstract

We investigate some important theoretical issues associated with the treatment of the spin-3/2 baryons in the effective Lagrangian theory. These are the form of the spin-3/2 particle propagator, off-shell parameters involving the spin-3/2 field; strategies of implementing gauge invariance, and unitarity. We comment on previous works by Peccei, Nath /ital et/ /ital al/., Williams, and Adelseck /ital et/ /ital al/., the last three works being in the context of recent revival of interest of baryon resonance structure in quantum chromodynamics. Our experience on the ..delta..(1232) resonance is invoked as a concrete example of dealing with these problems. Examples of some related problems in theories of massive vector and spin-3/2 particles, in pion decay and supersymmetry, respectively, are also discussed. These discussions should trigger new theoretical and experimental investigations in the study of baryon resonances excited from free hadrons and in complex nuclei.

Baryon physics from mesons in the realistic chiral soliton model

Miscellaneous Zhang, L

The prime objective of this thesis is to investigate, for the first time, baryon physics, in the leading order of 1/N{sub c} expansion (N{sub c} being the number of colors), from the {pi}{rho}{omega}{alpha}{sub 1} chiral soliton model, consistent with the low-energy features of quantum chromodynamics (QCD) and the known meson properties, as collected in the newest data base of the 1992 Particle Data Group (PDG). The {pi}{rho}{omega}a{sub 1}f{sub 1} meson effective action, used in this work, is based on the hidden gauge symmetry formalism, and has the most general form in the anomalous sector, with fourteen independent terms.

Observation of the doubly strange b-Baryon Ω_b^-

Thesis/Dissertation

This thesis reports the first experimental evidence of the doubly strange b-baryon Ω_b^- (ssb) following the decay channel Ω_b^- → J/Ψ(1S) μ⁺μ^- Ω^- Λ K^- p π^- in p$$\bar{p}$$ collisions at √s = 1.96 Tev. Using approximately 1.3 fb^-1 of data collected with the D0 detector at the Fermilab Tevatron Collider, they observe 17.8 ± 4.9(stat) ± 0.8(syst) Ω_b^- signal events at 6.165 ± 0.010(stat) ± 0.013(syst) GeV/c² with a corresponding significance of 5.4 σ, meaning that the probability of the signal coming from a fluctuation in the background is 6.7 x 10^-8.

Model-independent connections between pion photoproduction and Compton scattering in the. Delta. (1232) region

Journal Article Benmerrouche, M; Mukhopadhyay, N - Physical Review, D (Particles Fields); (United States)

We exploit Grushin {ital et} {ital al}.'s {ital independent} {ital determinations} of the real and the imaginary parts of the pion photoproduction multipoles in the {Delta}(1232) region, without the use of an approximate form of Watson's theorem, and obtain model-independent estimates for the Compton amplitudes for the resonance excitation off nucleons. We compare these with the results obtained from other analyses of photoproduction multipoles. We find the lower bound for the differential cross section using unitarity, and compare our results with available experiments, both the older-generation experiments, primarily at Bonn, and the preliminary results from the recent studies at themore »« less

Pole model of B -meson decays into baryon-antibaryon pairs

Journal Article Jarfi, M; Lazrak, O; Le Yaouanc, A; ... - Physical Review, D (Particles Fields); (USA)

We reconsider in detail the pole model for baryonic {ital B} decays, first crudely estimated by Deshpande {ital et} {ital al}. We make a complete calculation on the basis of the quark model by an extensive evaluation of strong- and weak-interaction vertices. We also consider charmed decays, and the previously lacking {ital J}{sup {ital P}}=1/2{sup {minus}} baryon poles that lead to large parity-violating amplitudes. The strong couplings are calculated in absolute magnitude by our quark-pair-creation model in a crossed channel. The effects of unequal quark masses are fully taken into account, correcting previous published results, and introducing a large setmore »« less

Effective-Lagrangian approach to the theory of pion photoproduction in the. Delta. (1232) region

Journal Article Davidson, R; Mukhopadhyay, N; Wittman, R - Physical Review, D (Particles Fields); (USA)

We investigate theoretical uncertainties and model dependence in the extraction of the nucleon-{Delta}(1232) electromagnetic transition amplitudes from the multipole data base. Our starting point is an effective Lagrangian incorporating chiral symmetry, which includes, at the tree level, the pseudovector nucleon Born terms, leading {ital t}-channel vector-meson exchanges, and {ital s}- and {ital u}-channel {Delta} exchanges. We express the nucleon-{Delta} transition magnetic dipole ({ital M}1) and electric quadrupole ({ital E}2) amplitudes in terms of two independent gauge couplings at the {gamma}{ital N}{Delta} vertex, and fit these to various multipole data sets. We find a large sensitivity to the method used inmore »« less
