Meson Condensation [PDF]

open access: yesParticles, 2019
We give a pedagogical review of the properties of the various meson condensation phases triggered by a large isospin or strangeness imbalance. We argue that these phases are extremely interesting and powerful playground for exploring the properties of ...

Vector-meson production and vector meson dominance [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We consider the fidelity of the vector meson dominance (VMD) assumption as an instrument for relating the electromagnetic vector-meson production reaction $$e + p \rightarrow e^\prime + V + p$$ e + p → e ′ + V + p to the purely hadronic process $$V + p ...

Meson-Meson and Meson-Baryon Interactions in Lattice QCD [PDF]

open access: yesAIP Conference Proceedings, 2006
We study the meson-meson and meson-baryon interactions in lattice QCD. The simulation is performed on 20^3 * 24 lattice at \beta=5.7 using Wilson gauge action and Wilson fermion at the quenched level.

Tetraquarks in the 1/N expansion and meson-meson resonances [PDF]

open access: yes, 2016
Diquarks are found to have the right degrees of freedom to describe the tetraquark poles in hidden-charm to open-charm meson-meson amplitudes. Compact tetraquarks result as intermediate states in non-planar diagrams of the 1/N expansion and the ...

Meson exchange models for Meson production [PDF]

open access: yesAIP Conference Proceedings, 1999
The production of mesons in nucleon-nucleon collisions is reviewed from the viewpoint of the meson-exchange picture. In the first part various possible production mechanisms and their relative importance are discussed.

Meson-meson Scattering in QCD-like Theories [PDF]

open access: yesJournal of High Energy Physics, 2011
We discuss meson-meson scattering at next-to-next-to-leading order in the chiral expansion for QCD-like theories with general $n$ degenerate flavours for the cases with a complex, real and pseudo-real representation. I.e.

Pseudoscalar meson and vector meson interactions and dynamically generated axial-vector mesons [PDF]

open access: yesPhysical Review D, 2014
The axial-vector mesons ${a}_{1}(1260)$, ${b}_{1}(1235)$, ${f}_{1}(1285)$, ${h}_{1}(1170)$, ${h}_{1}(1380)$, and ${K}_{1}(1270)$ are dynamically generated in the unitized chiral perturbation theory.

Meson-Meson Scattering in Relativistic Constraint Dynamics

open access: yesJournal of Physics: Conference Series, 2004
Dirac's relativistic constraint dynamics have been successfully applied to obtain a covariant nonperturbative description of QED and QCD bound states.

Meson-Meson Scattering in Lattice QED_2+1 [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1992
Scattering phase shifts of a meson-meson system in staggered 3-dimensional lattice QED are computed. The main task of the simulation is to obtain a discrete set of two-body energy levels.
