Baryon-baryon interactions from Effective Field Theory

open access: yesEPJ Web of Conferences, 2010
I report on recent progress in the description of baryon-baryon systems within chiral effective field theory. In particular, results for the hyperon-nucleon and hyperon-hyperon interactions as well as for strangeness S = −3 to −4 baryon-baryon systems ...

Negative Baryon density and the Folding structure of the B=3 Skyrmion [PDF]

open access: yes, 2013
The Skyrme model is a non-linear field theory whose solitonic solutions, once quantised, describe atomic nuclei. The classical static soliton solutions, so-called Skyrmions, have interesting symmetries and can only be calculated numerically ...

Finkelstein-Rubinstein constraints for the Skyrme model with pion masses [PDF]

open access: yes, 2006
The Skyrme model is a classical field theory modelling the strong interaction between atomic nuclei. It has to be quantized in order to compare it to nuclear physics.

Measurement of the Xi(-)(b) and Omega(-)(b) baryon lifetimes [PDF]

open access: yes, 2014
Using a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξ−b and Ω−b baryons are reconstructed in the Ξ−b → J/ψΞ− and Ω−b → J/ψΩ− decay modes and their lifetimes measured to be τ(Ξ−b) = 1.55+0.10−0.09 (stat) ± 0.03

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

The THREEHUNDRED project: The effect of baryon processes at galaxy cluster scale [PDF]

open access: yesEPJ Web of Conferences, 2022
The role of baryon models in hydrodynamic simulations is still unclear. Future surveys that use cluster statistics to precisely constrain cosmological models require a better understanding of the baryonic effects.

Tachyon-dependent Chern-Simons terms and the V-QCD baryon

open access: yesJournal of High Energy Physics, 2022
The structure of the five-dimensional Tachyon-Chern-Simons action and its relevance to single-baryon states in the context of the V-QCD models for holographic QCD with backreacting flavor are analyzed.

S(3) skyrmions and the rational map ansatz [PDF]

open access: yes, 2000
This paper discusses multi-skyrmions on the 3-sphere with variable radius L using the rational map ansatz. For baryon number B = 3,...,9 this ansatz produces the lowest energy solutions known so far.

Constraining baryon annihilation in the hadronic phase of heavy-ion collisions via event-by-event fluctuations

open access: yesPhysics Letters B, 2022
We point out that the variance of net-baryon distribution normalized by the Skellam distribution baseline, κ2[B−B¯]/〈B+B¯〉, is sensitive to the possible modification of (anti)baryon yields due to BB¯ annihilation in the hadronic phase.
