Thermal energy of a charm-meson molecule in a pion gas
Journal of High Energy PhysicsThe thermal corrections to the propagator of a loosely bound charm-meson molecule in a pion gas are calculated to next-to-leading order in the heavy-meson expansion using a zero-range effective field theory.

Meson turbulence at quark deconfinement from AdS/CFT
Nuclear Physics B, 2015 Based on the QCD string picture at confining phase, we conjecture that the deconfinement transition always accompanies a condensation of higher meson resonances with a power-law behavior, “meson turbulence”.

Superexotic K*+D*+K*+ bound state
Physics Letters BWe study a system made from K*+D*+K*+ with charge 3, isospin I=3/2, spin J=3, and a quark content of cd¯s¯us¯u, which make it highly exotic relative to the standard qq¯ structure of mesons.

In-medium properties of mesons
EPJ Web of Conferences, 2017 In the project B.4, the modification of meson properties (mass, width) in a nuclear medium has been studied in photoproduction of mesons off nuclear targets.

There is only one set of the correct values of fF, fD and fS coupling constants in SU(3) invariant Lagrangian of the vector-meson-baryon interactions [PDF]
EPJ Web of Conferences, 2019 One can prove, there is generally eight various ω − ø mixings forms in elementary particle physics, which on one side give different forms of the vector-meson-nucleon coupling constants through fF, fD and fS in SU(3) invariant Lagrangian of the vector ...

The sigma-meson exchange contribution to the muonic hydrogen Lamb shift [PDF]
EPJ Web of Conferences, 2019 The sigma(ξ)meson exchange contribution to the potential of the muon-proton interactionin muonichydrogen inducedbythe ξ-meson coupling to two photons is estimated. The transition form factor ξ → γγ is deduced from the quark model and experimental data on

Radiative decays of vector and pseudoscalar nonets
EPJ Web of Conferences, 2012 Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are ...

Distillation of scalar exchange by coherent hypernucleus production in antiproton–nucleus collisions
Physics Letters B, 2017 The total and angular differential cross sections of the coherent process p¯+AZ→ΛA(Z−1)+Λ¯ are evaluated at the beam momenta 1.5÷20 GeV/c within the meson exchange model with bound proton and Λ-hyperon wave functions.

Mass Spectrum of Noncharmed and Charmed Meson States in Extended Linear-Sigma Model
ParticlesThe mass spectrum of different meson particles is generated using an effective Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields and quark flavors, up, down, strange, and charm.

Threshold effects in hadron spectrum: a new spectroscopy?
EPJ Web of Conferences, 2018 The exploration of energies above the open-flavor threshold in the meson spectra has led to the appearance of unexpected states difficult to accommodate in the naive picture of a bound state of a quark and an antiquark.
