Baryon-baryon, meson-meson, and meson-baryon interactions in nonrelativistic QCD
Physical Review DVan der Waals potentials describing interactions between color-singlet mesons and/or baryons vanish at leading order in potential nonrelativistic quantum chromodynamics (pNRQCD). This result and constraints from Gauss’s law are used to prove that weakly coupled pNRQCD van der Waals potentials in generic non-Abelian gauge theories with only heavy quarks

Hadronic scattering in (1+1)D SU(2) lattice gauge theory from tensor networks
Journal of High Energy PhysicsWe present a first real-time study of hadronic scattering in a (1+1)-dimensional SU(2) lattice gauge theory with fundamental fermions using tensor-network techniques.

in Z Hadronic Decays DELPHI Collaboration
, 1995 A study of the production of strange octet and decuplet baryons in hadronic decays of the Z recorded by the DELPHI detector at LEP is presented. This includes the first measurement of the \Sigma \Sigma average multiplicity.

BARYON FRAGMENTATION FUNCTIONS AND DIQUARK STRUCTURE
, 1989 We present a simple dynamical model of baryon production which predicts the form of baryon fragmentation functions to be softer than that for mesons. These predictions are in good accord with recent measurements of the spectra of baryons produced in e+e-

Baryon number transfer and central net baryon density in elementary hadronic interactions
, 2002 New NA49 data on baryon and anti-baryon production in nucleon + proton interactions demonstrate the importance of isospin effects and asymmetric baryon pair production.

Double Visions, Double Fictions
, 2018 A fresh take on the dopplegänger and its place in Japanese film and literature-past and present Since its earliest known use in German Romanticism in the late 1700s, the word Dopplegänger (double-walker) can be found throughout a vast array of literature,

European Physical Journal C: Particles and FieldsThe baryon axial vector current is computed in a combined formalism in $$1/N_c$$ 1 / N c and chiral corrections. Flavor SU(3) symmetry breaking is accounted for in two ways: Implicitly through the integrals occurring in the one-loop graphs and explicitly

Gravitational form factors of the baryon octet in holographic QCD
Journal of High Energy PhysicsThe gravitational form factors (GFFs) of the baryon octet, including hyperons, are investigated in a bottom-up holographic QCD model that explicitly incorporates the SU(3) flavor symmetry breaking through the strange quark mass.

Stochastic Isocurvature Baryon Fluctuations, Baryon Diffusion, And Primordial Nucleosynthesis
, 1996 We examine effects on primordial nucleosynthesis from a truly random spatial distribution in the baryon-to-photon ratio (j). We generate stochastic fluctuation spectra characterized by different spectral indices and root-mean-square fluctuation ...
