Beam energy dependence of net-hyperon yield and its implication on baryon transport mechanism

Physics Letters B
In the constituent quark model, each quark inside a baryon carries 1/3 unit of the baryon number. An alternative picture exists where the center of a Y-shaped topology of gluon fields, called the baryon junction, carries a unit baryon number.

Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method

Frontiers in Physics, 2020
In this article, we review the HAL QCD method to investigate baryon-baryon interactions, such as nuclear forces in lattice QCD. We first explain our strategy in detail to investigate baryon-baryon interactions by defining potentials in field theories ...

Baryon number conservation and statistical production of antibaryons [PDF]

, 2005
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 ...

Interactions and decays of high-spin baryon resonances

EPJ Web of Conferences, 2012
Understanding strong interactions at low energy region requires the precise knowledge on the spectra and the properties of hadrons. Such informations can be obtained through detailed and sophisticated analyses of experimental data collected from various ...

Calculating Masses of Pentaquarks Composed of Baryons and Mesons

Advances in High Energy Physics, 2016
We consider an exotic baryon (pentaquark) as a bound state of two-body systems composed of a baryon (nucleon) and a meson. We used a baryon-meson picture to reduce a complicated five-body problem to simple two-body problems.

Vector Meson Propagator and Baryon Current Conservation

, 2001
If baryons couple only with $\omega $-mesons, one found the baryon spectral function may be negative. We show this unacceptable result is caused by the $k_\mu k_\nu $-terms in the $\omega $-meson propagator.

Quintessence and Spontaneous Leptogenesis

, 2001
We propose in this paper a scenario of spontaneous baryogenesis in cosmological models of Quintessence by introducing a derivative coupling of the Quintessence scalar $Q$ to the baryon current $J_B^{\mu}$ or the current of the baryon number minus lepton ...

Negative-Parity Baryons in Quenched Anisotropic Lattice QCD

, 2003
We study negative-parity baryon spectra in quenched anisotropic lattice QCD. The negative-parity baryons are measured as the parity partner of the ground-state baryons.
