Effects of three-baryon forces on kaon condensation in hyperon-mixed matter
Physics Letters B, 2021 Possibility of kaon-condensed phase in hyperon-mixed matter is considered on the basis of chiral symmetry for kaon-baryon and kaon-kaon interactions, being combined with the relativistic mean-field theory for two-body baryon interaction.

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

Generation of SU(3) sum rule for charmed baryon decay
Journal of High Energy Physics, 2022 Flavor SU(3) symmetry is a powerful tool to analyze charmed baryon decays. In this work, we propose an approach to generate SU(3) sum rules for the singly and doubly charmed baryon decays without writing the Wigner-Eckhart invariants explicitly. The SU(3)

Chiral Baryon Fields in the QCD Sum Rule
, 2012 We study the structure of local baryon fields using the method of QCD sum rule. We only consider the single baryon fields and calculate their operator product expansions. We find that the octet baryon fields belonging to the chiral representations [(3,3*)

Light particles with baryon and lepton numbers
Physics Letters B, 2021 We consider light new particles χ and ϕ that carry baryon and lepton numbers. If these particles are lighter than nucleons they lead to exotic decays such as p→π+χ and p→e+ϕ, not yet fully constrained by dedicated searches.

The eta' in baryon chiral perturbation theory
, 2000 We include in a systematic way the eta' in baryon chiral perturbation theory. The most general relativistic effective Lagrangian describing the interaction of the lowest lying baryon octet with the Goldstone boson octet and the eta' is presented up to ...

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 ...

Aharonov–Bohm protection of black hole's baryon/skyrmion hair
Physics Letters B, 2017 The baryon/skyrmion correspondence implies that the baryon number is encoded into a topological surface integral. Under certain conditions that we clarify, this surface integral can be measured by an asymptotic observer in form of an Aharonov–Bohm phase ...

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.
