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 ...

On the Baryon Fractions in Clusters and Groups of Galaxies [PDF]

, 2010
We present the baryon fractions of 2MASS groups and clusters as a function of cluster richness using total and gas masses measured from stacked ROSAT X-ray data and stellar masses estimated from the infrared galaxy catalogs. We detect X-ray emission even

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*)

A Note on Baryon-Baryon Interaction [PDF]

Progress 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 spectroscopy [PDF]

Reviews of Modern Physics, 2010
About 120 baryons and baryon resonances are known, from the abundant nucleon with $u$ and $d$ light-quark constituents up to the recently discovered $ _b^-=bss$, and the $ _b^-=bsd$ which contains one quark of each generation. In spite of this impressively large number of states, the underlying mechanisms leading to the excitation spectrum are not ...

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.

Correlation length of the angular mode for an approximate U(1) symmetry during inflation

Physics Letters B, 2023
It is known that a light scalar field obtains fluctuations in the de Sitter inflationary background. Such fluctuations could provide an initial condition for baryogenesis through the Affleck-Dine mechanism, where an approximate U(1)B symmetry is usually ...

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 ...

Baryon Number Transport via Gluonic Junctions [PDF]

, 1998
A novel non-perturbative gluon junction mechanism is introduced within the HIJING/B nuclear collision event generator to calculate baryon number transport and hyperon production in pA and AA collisions. This gluonic mechanism can account for the observed
