A Note on Baryon-Baryon Interaction [PDF]

open access: yesProgress of Theoretical Physics, 1961
The process of a ( XI /sup -/ n) collision giving rise to hyperon systems is studied, the possibility of a bound state in the final system being also envisaged. The implication arising from the various parity assignments for the hyperons is discussed and the decay distribution of the possible bound system is analyzed. (L.N.N.)

Baryon Asymmetry, Dark Matter and Local Baryon Number [PDF]

open access: yes, 2014
We propose a new mechanism to understand the relation between the baryon and dark matter asymmetries in the universe in theories where the baryon number is a local symmetry.

Baryon-baryon interactions from Effective Field Theory

open access: yesEPJ 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

open access: yesGalaxies, 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.

Baryon Number Fluctuation and the Quark-Gluon Plasma [PDF]

open access: yes, 2001
We show that $\omega_B$ or $\omega_{\bar B}$, the squared baryon or antibaryon number fluctuation per baryon or antibaryon, is a possible signature for the quark-gluon plasma that is expected to be created in relativistic heavy ion collisions, as it is a

Baryon-baryon interactions from the lattice [PDF]

open access: yes, 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.

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.

Direct baryogenesis in the broken phase

open access: yesJournal 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

Cosmological Dynamics of Interacting Dark Energy and Dark Matter in f(Q)$f(Q)$ Gravity

open access: yesFortschritte der Physik, EarlyView.
Abstract In this work, the behavior of interacting dark energy (DE) and dark matter (DM) within a model of f(Q)$f(Q)$ gravity is explored, employing the standard framework of dynamical system analysis. The power‐law f(Q)$f(Q)$ model is considered, incorporating two different forms of interacting DE and DM: 3αHρm$3\alpha H\rho _m$ and α3HρmρDE$\frac ...

Baryon-baryon interactions in free space and baryonic medium

open access: yes, 2003
We study the interactions of the octet baryons in a relativistic meson exchange approach connecting free-space and in-medium interactions with those in finite (hyper)nuclei. A short sketch of the model including the relativistic T- and G-matrix and the mapping of the G-matrix onto density dependent vertex functionals in the density dependent ...
