Hadron resonance gas with repulsive interactions and fluctuations of conserved charges
Physics Letters B, 2018 We discuss the role of repulsive baryon–baryon interactions in a hadron gas using relativistic virial expansion and repulsive mean field approaches. The fluctuations of the baryon number as well as strangeness-baryon correlations are calculated in the ...

Physics Letters B, 2021 The baryon form factor of charged pions arises since isospin symmetry is broken. We obtain estimates for this basic property in two phenomenological ways: from simple constituent quark models with unequal up and down quark masses, and from fitting to e+e−

Canadian Journal of Physics, 2000 We describe classical orbits and quantum states of a three-particle system, which is weakly chaotic. The quantum energies of the lowest 48 states, which are invariant under permutations, are given both for various approximations and to high accuracy. The quantum mechanical probability distributions are given in a two-dimensional version of the system,

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

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.)

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 ...

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
UniverseWe 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.
