Meson-baryon scattering lengths in heavy baryon chiral perturbation theory

open access: yes, 2007
We calculate the chiral corrections to the s-wave pseudoscalar meson octet-baryon scattering lengths a(MB) to O(p(3)) in the SU(3) heavy baryon chiral perturbation theory (HB chi PT).

Triple-charmed hadron from coalescence in relativistic heavy-ion collisions

open access: yesPhysics Letters B
We investigate the production of the Ωccc baryon in relativistic heavy-ion collisions. Unlike proton-proton collisions, nuclear collisions produce both deconfined matter and abundant charm quark pairs, which can coalesce to form the Ωccc baryon, thereby ...

Short-range baryon-baryon potentials in constituent quark model revisited

open access: yes, 2023
We revisit the short-range baryon-baryon potentials in the flavor SU(3) sector, using the constituent quark model. We employ the color Coulomb, linear confining, and color magnetic forces between two constituent quarks, and solve the three-quark Schr\"{o}

Hadronic scattering in (1+1)D SU(2) lattice gauge theory from tensor networks

open access: yesJournal of High Energy Physics
We 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

open access: yes, 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

open access: yes, 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-

Resonant Enhancement for the transfer of baryon number from a CP-violating hidden sector

open access: yesEuropean Physical Journal C: Particles and Fields
We consider a scenario where the baryon asymmetry in the SM arises from a portal coupling to a CP-violating hidden sector, without any explicit violation of baryon or lepton number in either sector.

Baryon number transfer and central net baryon density in elementary hadronic interactions

open access: yes, 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.

Universality of the baryon axial vector current operator in large- $$N_c$$ N c chiral perturbation theory

open access: yesEuropean Physical Journal C: Particles and Fields
The 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

Stochastic Isocurvature Baryon Fluctuations, Baryon Diffusion, And Primordial Nucleosynthesis

open access: yes, 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 ...
