Dependence of net-hyperon production at mid-rapidity on beam energy and its implication on baryon number carrier [PDF]

EPJ Web of Conferences
The conventional picture of baryon number is that each valence quark inside a baryon carries 1/3 unit of baryon number. However, an alternative picture exists where the center of a Y-shaped topology of gluon fields, called the baryon junction, carries 1 ...

Baryon–Baryon interactions from lattice QCD [PDF]

Chinese Physics C, 2010
We report on new attempt to investigate baryon-baryon interactions in lattice QCD. From the Bethe-Salpeter (BS) wave function, we have successfully extracted the nucleon-nucleon ($NN$) potentials in quenched QCD simulations, which reproduce qualitative features of modern $NN$ potentials.

Baryon and Lepton Number Assignment in $E_6$ Models [PDF]

, 1995
In $E_6$ models there are new particles whose baryon number is not uniquely assigned. We point out that the baryon and lepton number assignment to these particles can change the baryogenesis scenario significantly.

Lattice QCD at finite baryon density using analytic continuation

EPJ Web of Conferences, 2018
We simulate lattice QCD with two flavors of Wilson fermions at imaginary baryon chemical potential. Results for the baryon number density computed in the confining and deconfining phases at imaginary baryon chemical potential are used to determine the ...

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*)

Importance of Baryon-Baryon Coupling in Hypernuclei [PDF]

, 1994
The $\Lambda N - \Sigma N$ coupling in $\Lambda$--hypernuclei and $\Lambda \Lambda - \Xi N$ coupling in $\Lambda \Lambda$--hypernuclei produce novel physics not observed in the conventional, nonstrange sector.

Tensor Amplitudes for Partial Wave Analysis of $\mathit{\psi }\mathbf{\to }\mathbf{\Delta }\overline{\mathbf{\Delta }}$ within Helicity Frame

Universe
We have derived the tensor amplitudes for partial wave analysis of ψ→ΔΔ¯, Δ→pπ within the helicity frame, as well as the amplitudes for the other decay sequences with same final states.

Evolution of Baryon-Free Matter Produced in Relativistic Heavy-Ion Collisions

, 2003
A 3-fluid hydrodynamic model is introduced for simulating heavy-ion collisions at incident energies between few and about 200 AGeV. In addition to the two baryon-rich fluids of 2-fluid models, the new model incorporates a third, baryon-free (i.e.

Dark Matter, Baryon Asymmetry, and Spontaneous B and L Breaking [PDF]

, 2010
We investigate the dark matter and the cosmological baryon asymmetry in a simple theory where baryon (B) and lepton (L) number are local gauge symmetries that are spontaneously broken.

Diquark Study in Quark Model

Particles
To investigate diquark correlation in baryons, the baryon spectra with different light–heavy quark combinations are calculated using Gaussian expansion method within both the naive quark model and the chiral quark model. By computing the diquark energies
