Pseudoscalar Mesons and Emergent Mass

Few-Body Systems
AbstractDespite its role in the continuing evolution of the Universe, only a small fraction of the mass of visible material can be attributed to the Higgs boson alone. The overwhelmingly dominant share may/should arise from the strong interactions that act in the heart of nuclear matter; namely, those described by quantum chromodynamics.

q‐Deformed Glueball Spectrum in AdS/QCD Correspondence

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
This work presents the application of the q‐algebra in the glueball spectrum. This algebra is implemented through Jackson’s derivatives in a Schrödinger‐like equation resulting from the gravity fluctuations around the braneworld scenario in five dimensions.

Covariant Spectator Theory of heavy–light and heavy mesons and the predictive power of covariant interaction kernels

Physics Letters B, 2017
The Covariant Spectator Theory (CST) is used to calculate the mass spectrum and vertex functions of heavy–light and heavy mesons in Minkowski space. The covariant kernel contains Lorentz scalar, pseudoscalar, and vector contributions.

Negative Parity N* Resonances in an Extended GBE

, 2003
In this paper, we calculate the masses and mixing angles of L=1 negative parity N* resonances in an extended GBE (Goldstone-boson-exchange model) with harmonic-oscillator wave functions.

Pseudoscalar meson physics with four dynamical quarks [PDF]

, 2012
We present preliminary results for light, strange and charmed pseudoscalar meson physics from simulations using four flavors of dynamical quarks with the highly improved staggered quark (HISQ) action.

The annihilation of virtual photons into pseudoscalar mesons [PDF]

The European Physical Journal C, 2001
We investigate the possibility to constrain the pion distribution amplitude from the gamma* gamma* -> pi transition. For a surprisingly large range in the two photon virtualities we find that the transition form factor is essentially independent of the distribution amplitude. This in turn entails a parameter-free prediction of QCD. The gamma* gamma*

Meson Masses and Mixing Angles in 2+1 Flavor Polyakov Quark Meson Sigma Model and Symmetry Restoration Effects

, 2010
The meson masses and mixing angles have been calculated for the scalar and pseudoscalar sector in the framework of the generalized 2+1 flavor Polyakov loop augmented quark meson linear sigma model. We have given the results for two different forms of the

Soft two-meson-exchange nucleon-nucleon potentials. I. Planar and crossed-box diagrams [PDF]

, 1996
Pion-meson-exchange nucleon-nucleon potentials are derived for two nucleons in the intermediate states. The mesons we include are (i) pseudoscalar mesons: $\pi, \eta, \eta'$; (ii) vector mesons: $\rho, \omega, \phi$; (iii) scalar mesons: $a_{0}(980 ...

Pseudoscalar Meson and Charmed Baryon Scattering Lengths [PDF]

, 2012
We have calculated the scattering lengths between the pseudoscalar meson and charmed triplet, sextet, and excited sextet baryon to the third order with the heavy baryon chiral perturbation theory. The chiral expansion of the pion channels converges well.
