The imprint of conservation laws on correlated particle production
Journal of High Energy PhysicsThe study of event-by-event fluctuations of net-baryon number in a subspace of full phase space is a promising direction for deciphering the structure of strongly interacting matter created in collisions of relativistic heavy nuclei.

Mass predictions of triply heavy hybrid baryons via QCD sum rules
European Physical Journal C: Particles and Fields, 2023 In this article, we study the mass spectrum of the low-lying triply heavy hybrid baryon, which consists of three valence heavy quarks in a color octet and one valence gluon, with spin-parity $$J^P=(\frac{1}{2})^+$$ J P = ( 1 2 ) + via QCD sum rules. This

Meson-Baryon Scattering in QCD_2 for any Coupling
, 2003 Extending earlier work on strong-coupling meson-baryon scattering in QCD_2, we derive the effective meson-baryon action for any value of the coupling constant, in the large-N_c limit.

On Extracting Thermal Parameters and Scenario in High‐Energy Collisions
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.The inconsistent thermal parameters derived from various models in high‐energy collisions are examined. A comprehensive literature review suggests model‐independent parameters to address these inconsistencies, based on the average transverse momentum 〈pT〉 and root‐mean‐square transverse momentum pT2.

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 ...

Possible molecular dibaryons with csssqq quarks and their baryon–antibaryon partners
European Physical Journal C: Particles and Fields, 2023 In this work, we systematically investigate the charmed–strange dibaryon systems with csssqq quarks and their baryon–antibaryon partners from the interactions $$\varXi ^{(',*)}_{c}\varXi ^{(*)}$$ Ξ c ( ′ , ∗ ) Ξ ( ∗ ) , $$\varOmega ^{(*)}_c\varLambda ...

Baryons 2002, 2003 We review the status of hybrid baryons. The only known way to study hybrids rigorously is via excited adiabatic potentials. Hybrids can be modelled by both the bag and flux-tube models. The low-lying hybrid baryon is N 1/2^+ with a mass of 1.5-1.8 GeV. Hybrid baryons can be produced in the glue-rich processes of diffractive gamma N and pi N production,

On the Square Speed of Sound in High‐Energy Collisions: Range of Values and How to Understand It
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.After reviewing the sound speeds in various forms and conditions of matter, we investigate the sound speed of hadronic matter that has decoupled from the hot and dense system formed during high‐energy collisions. We comprehensively consider factors such as energy loss of the incident beam, rapidity shift of leading nucleons, and the Landau hydrodynamic

Interactions and decays of high-spin baryon resonances
EPJ Web of Conferences, 2012 Understanding strong interactions at low energy region requires the precise knowledge on the spectra and the properties of hadrons. Such informations can be obtained through detailed and sophisticated analyses of experimental data collected from various ...
