Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at $$\sqrt{\mathrm{s}}=7$$ s = 7  TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
Two-particle angular correlations were measured in pp collisions at $$\sqrt{s} = 7$$ s = 7  TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected peak dominated by effects

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

Many-Quark Interactions: Large-N Scaling and Contribution to Baryon Masses

open access: yesUniverse, 2022
Starting from an effective Hamiltonian modeling, of a baryon made of N identical quarks in the large-N approach of QCD, we obtain analytical formulas, allowing to estimate the contributions of multiquark interactions to the baryon mass.

Hadron resonance gas with repulsive interactions and fluctuations of conserved charges

open access: yesPhysics 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 ...

BARYONS WITH HOLOGRAPHY [PDF]

open access: yesModern Physics Letters A, 2008
We perform the first study of baryons in holographic QCD with [Formula: see text] multi-D-brane system in type IIA superstring theory. The baryon is described as a chiral soliton solution in the four-dimensional meson effective action derived from holographic QCD.

Baryonic content of the pion

open access: yesPhysics 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−

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

open access: yesEPJ 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 ...

The Baryon asymmetry in the Standard Model with a low cut-off [PDF]

open access: yes, 2004
We study the generation of the baryon asymmetry in a variant of the standard model, where the Higgs field is stabilized by a dimension-six interaction. Analyzing the one-loop potential, we find a strong first order electroweak phase transition for Higgs ...

The linear baryon

open access: yesCanadian 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,
