Meson turbulence at quark deconfinement from AdS/CFT

open access: yesNuclear 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”.

B-Meson Wavefunction in the Wandzura-Wilczek Approximation

open access: yes, 2005
The B-meson wavefunction has been studied with the help of the vacuum-to-meson matrix element of the nonlocal operators in the heavy quark effective theory.

Isospin dependence of the eta prime meson production in nucleon-nucleon collisions [PDF]

open access: yes, 2008
A comparison of the close-to-threshold total cross section for the eta prime production in pp --> pp eta prime and pn --> pn eta prime reactions constitutes a tool to investigate the eta prime meson structure and the reaction mechanism in the channels of

Neutral $B$ meson mixings and $B$ meson decay constants with static heavy and domain-wall light quarks [PDF]

open access: yes, 2014
Neutral $B$ meson mixing matrix elements and $B$ meson decay constants are calculated. Static approximation is used for $b$ quark and domain-wall fermion formalism is employed for light quarks.

Meson B fragmentation function with consideration of mass corrections

open access: yesIranian Journal of Physics Research, 2019
Study of B meson (meson with the bottom quark flavor) in Large Hadron Collider (LHC) is of special importance so that the detector LHCb is devoted to investigate these types of mesons.

The sigma-meson exchange contribution to the muonic hydrogen Lamb shift [PDF]

open access: yesEPJ 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

The UTfit collaboration average of D meson mixing data: Winter 2014 [PDF]

open access: yes, 2014
A bstractWe update the analysis of D meson mixing including the latest experimental results as of January 2014. We derive constraints on the parameters M12, Γ12 and Φ12 that describe D meson mixing using all available data, allowing for CP violation.

A Model of Mesons [PDF]

open access: yesviXra, 2017
Detailed models of mesons have been derived in terms of real structured particles, in order to replace the formless quark/anti-quark singularities of standard QCD theory. Pion design is related to the muonic mass, and a Yukawa potential is calculated for the hadronic field.

Spectrum of mesons and hyperfine dependence potentials

open access: yesIranian Journal of Physics Research, 2006
In most models, mesons consist of quark -antiquark pairs moving in a confining potential. However, it would be interesting to consider the effect of an extra residual interaction by introducing the quark particles which contain a dependent spin and ...

In-medium properties of mesons

open access: yesEPJ 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.
