Evolution of Baryon-Free Matter Produced in Relativistic Heavy-Ion Collisions
, 2003 A 3-fluid hydrodynamic model is introduced for simulating heavy-ion collisions at incident energies between few and about 200 AGeV. In addition to the two baryon-rich fluids of 2-fluid models, the new model incorporates a third, baryon-free (i.e.

Baryon Number Conservation and Statistical Production of Antibaryons [PDF]
, 2000 The statistical production of antibaryons is considered within the canonical ensemble formulation. We demonstrate that the antibaryon suppression in small systems due to the exact baryon number conservation is rather different in the baryon-free (B=0 ...

AIP Conference Proceedings, 2010 Galaxies are composed of baryonic stars and gas embedded in dark matter halos. Here I briefly review two aspects of the connection between baryons and their halos. (1) The observed baryon content of galaxies falls short of the cosmic baryon fraction by an amount that varies systematically with mass. Where these missing baryons now reside is unclear. (2)

Antimatter Gravity and the Results of the ALPHA‐g Experiment
Annalen der Physik, Volume 536, Issue 7, July 2024.The recent results of the ALPHA‐g experiment, which show gravitational attraction between antihydrogen atoms and the Earth, seem to undermine the success of repulsive‐gravity models in the cosmological field. Analyzing the theory of CPT gravity, two solutions are found that are consistent with the experimental results, while preserving the large‐scale ...

Differing Interactions Require Baryon and Lepton Conservation [PDF]
arXiv, 1998 Baryon and lepton numbers are conserved. Why? Baryon number must be because baryons are subject to strong interactions, leptons are not. Conservation of baryons leads to that of leptons. This raises further questions which are noted.

Cylindrically Symmetric Diffusion Model for Relativistic Heavy‐Ion Collisions
Annalen der Physik, Volume 536, Issue 5, May 2024.To account for particle production in relativistic heavy‐ion collisions at the Large Hadron Collider, a relativistic diffusion model with cylindrical symmetry is derived from nonequilibrium–statistical considerations. It propagates an initial state based on quantum chromodynamics in time toward a thermal equilibrium limit.

Physics Letters B, 2019 We study baryon-baryon scattering by applying time-ordered perturbation theory to the manifestly Lorentz-invariant formulation of SU(3) baryon chiral perturbation theory.

Physics Letters B, 2021 The baryon form factor of charged pions arises since isospin symmetry is broken. We obtain estimates for this basic property in two phenomenological ways: from simple constituent quark models with unequal up and down quark masses, and from fitting to e+e−

Possible molecular dibaryons with csssqq quarks and their baryon–antibaryon partners
European Physical Journal C: Particles and Fields, 2023 In this work, we systematically investigate the charmed–strange dibaryon systems with csssqq quarks and their baryon–antibaryon partners from the interactions $$\varXi ^{(',*)}_{c}\varXi ^{(*)}$$ Ξ c ( ′ , ∗ ) Ξ ( ∗ ) , $$\varOmega ^{(*)}_c\varLambda ...

Baryon/anti-baryon inhomogeneity and big bang nucleosynthesis [PDF]
arXiv, 1998 We investigate the effects of baryon/anti-baryon inhomogeneity on primordial nucleosynthesis. Recent work claims that electroweak baryogenesis could give rise to distinct regions of net baryon and anti-baryon number, which could survive until the nucleosynthesis epoch.
