Light particles with baryon and lepton numbers

open access: yesPhysics 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.

Effects of three-baryon forces on kaon condensation in hyperon-mixed matter

open access: yesPhysics 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.

Baryon Production in the String Fragmentation Picture [PDF]

open access: yes, 1996
An improved version of the ``pop-corn'' model for baryon production in quark and gluon jets is presented. With a reduced number of parameters the model reproduces well both production rates for different baryon species and baryon momentum distributions ...

On the estimation of the strange quark mass from the experimental data on the light baryon octet

open access: yesЯдерна фізика та енергетика, 2018
Simple relations connecting the strange quark mass to the splittings of the light hyperon masses were obtained on the basis of the phenomenological quark model compatible with the present-day theory of strong interactions, i.e.

Density-dependent effective baryon–baryon interaction from chiral three-baryon forces [PDF]

open access: yesNuclear Physics A, 2017
A density-dependent effective potential for the baryon-baryon interaction in the presence of the (hyper)nuclear medium is constructed, based on the leading (irreducible) three-baryon forces derived within SU(3) chiral effective field theory. We evaluate the contributions from three classes: contact terms, one-pion exchange and two-pion exchange. In the

Tachyon-dependent Chern-Simons terms and the V-QCD baryon

open access: yesJournal of High Energy Physics, 2022
The structure of the five-dimensional Tachyon-Chern-Simons action and its relevance to single-baryon states in the context of the V-QCD models for holographic QCD with backreacting flavor are analyzed.

The THREEHUNDRED project: The effect of baryon processes at galaxy cluster scale [PDF]

open access: yesEPJ Web of Conferences, 2022
The role of baryon models in hydrodynamic simulations is still unclear. Future surveys that use cluster statistics to precisely constrain cosmological models require a better understanding of the baryonic effects.

Baryon Number Transport in a Cosmic QCD-Phase Transition [PDF]

open access: yes, 1994
We investigate the transport of baryon number across phase boundaries in a putative first order QCD-phase transition. Two independent phenomenological models are employed to estimate the baryon penetrability at the phase boundary: chromoelectric flux ...

The V-QCD baryon: numerical solution and baryon spectrum

open access: yesJournal of High Energy Physics, 2023
The single baryon solution of V-QCD is numerically computed. The spectrum of spin and isospin modes is also computed by quantizing the light fluctuations around the baryon.
