Baryon-baryon interactions from Effective Field Theory
EPJ Web of Conferences, 2010 I report on recent progress in the description of baryon-baryon systems within chiral effective field theory. In particular, results for the hyperon-nucleon and hyperon-hyperon interactions as well as for strangeness S = −3 to −4 baryon-baryon systems ...

Favored Inflationary Models by Scalar Field Condensate Baryogenesis
Galaxies, 2021 We calculate the baryon asymmetry value generated in the Scalar Field Condensate (SCF) baryogenesis model obtained in several inflationary scenarios and different reheating models.

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 ...

Baryon-baryon interactions from the lattice [PDF]
, 2008 I discuss the latest progress in calculating baryon-baryon interactions with lattice QCD. The latest results from the NPLQCD collaboration for nucleon-nucleon scattering along with preliminary calculations of hyperon-nucleon scattering are presented.

Glueball–baryon interactions in holographic QCD
Physics Letters B, 2017 Studying the Witten–Sakai–Sugimoto model with type IIA string theory, we find the glueball–baryon interaction is predicted in this model. The glueball is identified as the 11D gravitational waves or graviton described by the M5-brane supergravity ...

Direct baryogenesis in the broken phase
Journal of High Energy Physics, 2020 We show a new mechanism for baryogenesis where the reheating temperature can be smaller than the electroweak scale. The baryon number symmetry is violated by a dimension nine operator which conserves a baryon parity. A high energy quark from the decay of

Astronomische Nachrichten, EarlyView.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Meson-meson correlations in baryon-baryon and antibaryon-baryon interactions [PDF]
Progress in Particle and Nuclear Physics, 1996 Recent work of the J lich group about the role of meson-meson correlations in baryon-baryon and antibaryon-baryon interactions is reviewed.
