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 ...

Baryon-Baryon-Meson Coupling Constants in QCD
AIP Conference Proceedings, 2010 The strong coupling constant of decuplet and octet baryons to vector and pseudoscalar mesons are calculated in light cone QCD sum rules in general case and when the SU(3)f symmetry is taken into account. A comparison of the obtained results with the existing experimental data and predictions of the other nonperturbative approaches is also made.

Baryonic resonances from baryon decuplet-meson octet interaction [PDF]
Nuclear Physics A, 2005 The s-wave interactions of the baryon decuplet with the octet of pseudoscalar mesons is studied in a unitarized coupled channel approach. We obtain a fair agreement for mass and width of several [Formula: see text] resonances. In particular, the Ξ(1820), the Λ(1520) and the Σ(1670) states are well reproduced.

Fortschritte der Physik, Volume 73, Issue 9-10, October 2025.Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

Correlation length of the angular mode for an approximate U(1) symmetry during inflation
Physics Letters B, 2023 It is known that a light scalar field obtains fluctuations in the de Sitter inflationary background. Such fluctuations could provide an initial condition for baryogenesis through the Affleck-Dine mechanism, where an approximate U(1)B symmetry is usually ...

Intermediate range baryon-baryon potentials
Physics Letters B, 1975 Abstract Information about the sign and strength of the two pion exchange contribution to the baryon-baryon potentials is obtained by relating them to the corresponding NN and NΛ potentials.

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

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

Confining Bond Rearrangement in the Random Center Vortex Model
, 2016 We present static meson-meson and baryon--anti-baryon potentials in Z(2) and Z(3) random center vortex models for the infrared sector of Yang-Mills theory, i.e., hypercubic lattice models of random vortex world-surfaces.

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.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 ...
