Masses of ground-state mesons and baryons, including those with heavy quarks
(Amer Physical Soc, 2019-08-09)
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 (g) over bar) mesons, scalar and axial-vector (fg) diquarks, ...
Spectrum and structure of octet and decuplet baryons and their positive-parity excitations
(Amer Physical Soc, 2019-09-13)
A continuum approach to the three-valence-quark bound-state problem in quantum field theory, employing parametrizations of the necessary kernel elements, is used to compute the spectrum and Poincare-covariant wave functions ...

Mitigating baryonic effects with a theoretical error covariance
(Oxford Univ Press, 2021-11-01)
One of the primary sources of uncertainties in modelling the cosmic-shear power spectrum on small scales is the effect of baryonic physics. Accurate cosmology for stage-IV surveys requires knowledge of the matter power ...

Occupation number formalism for arbitrary Nc baryons
(Elsevier Science, 2006-12)
A general method is presented for computing matrix elements of quark operators on baryonic states with low strangeness and arbitrary number of colors Nc. These results are useful in applications of the large Nc expansion ...
The baryon mass function for galaxy clusters
(Edp Sciences, 2006-06)
Context.The evolution of the cluster abundance with redshift is known to be a powerful cosmological constraint when applied to X-ray clusters. Recently, the evolution of the baryon mass function has been proposed as a new ...
Scaling law for baryon coupling to its current and its possible applications
(1997-09-21)
The baryon coupling to its current (λB), in conventional QCD sum rule calculations (QCDSR), is shown to scale as the cubic power of the baryon mass, MB. Some theoretical justification for it comes from a simple light-cone ...
