Title: Masses of ground-state mesons and baryons, including those with heavy quarks

Abstract

Using a confining, symmetry-preserving regularization of a vector x vector contact interaction, we compute the spectra of ground-state pseudoscalar and vector of ($$f$$$\bar{g}$$) mesons, scalar and axial-vector ($fg$) diquarks, and $$J^{P}$$ = 1/2(+), 3/2(+) ($fgh$) baryons, where $f, g, h$$ is an element of {$$u, d, s, c, b$}. The diquark correlations are essentially dynamical and play a key role in formulating and solving the three-valence-quark baryon problems. The baryon spectrum obtained from this largely algebraic approach reproduces the 22 known experimental masses with an accuracy of 2.9(2.4)%. It also possesses the richness of states typical of constituent-quark models, predicting many heavy-quark baryons not yet observed. This study indicates that diquark correlations are an important component of all baryons; and owing to the dynamical character of the diquarks, it is typically the lightest allowed diquark correlation that defines the most important component of a baryon's Faddeev amplitude.

Parity partners in the baryon resonance spectrum

Journal Article Lu, Ya ; Chen, Chen ; Roberts, Craig D. ; ... - Physical Review C

Here, we describe a calculation of the spectrum of flavor-SU(3) octet and decuplet baryons, their parity partners, and the radial excitations of these systems, made using a symmetry-preserving treatment of a vector x vector contact interaction as the foundation for the relevant few-body equations. Dynamical chiral symmetry breaking generates nonpointlike diquarks within these baryons and hence, using the contact interaction, flavor-antitriplet scalar, pseudoscalar, vector, and flavor-sextet axial-vector quark-quark correlations can all play active roles. The model yields reasonable masses for all systems studied and Faddeev amplitudes for ground states and associated parity partners that sketch a realistic picture of theirmore »« less

Structure of the nucleon’s low-lying excitations

Journal Article Chen, Chen ; El-Bennich, Bruno ; Roberts, Craig D. ; ... - Physical Review D

Here, a continuum approach to the three valence-quark bound-state problem in quantum field theory is used to perform a comparative study of the four lightest (I = 1/2, J^P = 1/2^±) baryon isospin doublets in order to elucidate their structural similarities and differences. Such analyses predict the presence of nonpointlike, electromagnetically active quark-quark (diquark) correlations within all baryons; and in these doublets, isoscalar-scalar, isovector-pseudovector, isoscalar-pseudoscalar, and vector diquarks can all play a role. In the two lightest (1/2,1/2⁺) doublets, however, scalar and pseudovector diquarks are overwhelmingly dominant. The associated rest-frame wave functions are largely S-wave in nature; and the firstmore »« less

New relation between mesons and baryons

Journal Article Robson, D - Phys. Rev., D; (United States)

A new SU/sub 12/ classification scheme for mesons and baryons is used in conjunction with a simple quark model and results in a striking correlation between the masses of the diquark subsystems in baryons and the masses of several known mesons. The new classification provides a simple scheme which involves a basic 36 multiplet for the pseudoscalar and vector mesons and a 112 multiplet for the baryons and antibaryons. The 36 multiplet of SU/sub 12/ does not treat the eta' as a singlet as in the conventional SU/sub 6/ scheme. The new scheme also has the advantages of providing amore »« less

Mesonic eightfold way from dynamics and confinement in strongly coupled lattice quantum chromodynamics

Journal Article Francisco Neto, Antonio ; O'Carroll, Michael ; Faria da Veiga, Paulo A - Journal of Mathematical Physics

We show the existence of all the 36 eightfold way mesons and determine their masses and dispersion curves exactly, from dynamical first principles such as directly from the quark-fluon dynamics. We also give a proof of confinement below the two-meson energy threshold. For this purpose, we consider an imaginary time functional integral representation of a 3+1 dimensional lattice QCD model with Wilson action, SU(3){sub f} global and SU(3){sub c} local symmetries. We work in the strong coupling regime, such that the hopping parameter {kappa}>0 is small and much larger than the plaquette coupling {beta}>1/g{sub 0}{sup 2}{>=}0 ({beta}<<{kappa}<<1). In the quantummore »« less

Diquark effects in light baryon correlators from lattice QCD

Journal Article DeGrand, Thomas ; Zhaofeng, Liu ; Schaefer, Stefan ; ... - Physical Review. D, Particles Fields

We study the role of diquarks in light baryons through point-to-point baryon correlators. We contrast results from quenched simulations with ones with two flavors of dynamical overlap fermions. The scalar, pseudoscalar, and axial vector diquarks are combined with light quarks to form color singlets. The quenched simulation shows large zero-mode effects in correlators containing the scalar and pseudoscalar diquark. The two scalar diquarks created by {gamma}{sub 5} and {gamma}{sub 0}{gamma}{sub 5} lead to different behavior in baryon correlators, showing that the interaction of diquarks with the third light quark matters: we do not see an isolated diquark. In our quarkmore »« less
