Further evidence for a large glue component in the f0(1500) meson

, 2002
We argue that the experimental decay rates of the f0(1500) meson into two pseudoscalar mesons and into two photons are incompatible with a quark-antiquark state and that the f0(1710) meson is dominantly an ssbar state.Comment: 11 ...

Millimeter‐Wave WISP Search with Coherent Light‐Shining‐Through‐a‐Wall Toward the STAX Project

Annalen der Physik, Volume 536, Issue 1, January 2024.
This research article shows potential of millimeter waves for searching dark photons, one of the candidates of dark matter. By sharing a common reference signal, an excellent temporal coherency is achieved between production and detection of dark photons.

Probing the transversity spin structure of a nucleon in neutrino-production of a charmed meson

EPJ Web of Conferences, 2016
Including O(mc) terms in the coefficient functions and/or O(mD) twist 3 contributions in the heavy meson distribution amplitudes leads to a non-zero transverse amplitude for exclusive neutrino production of a D pseudoscalar charmed meson on an ...

Mixing of eta-eta' Mesons in J/psi Decays into a Vector and a Pseudoscalar Meson

, 1997
The octet-singlet mixing angle $\theta_P$ in the pseudoscalar meson nonet is deduced from the rich set of accurate data on $J/\psi$ decays into a vector and a pseudoscalar meson.

Primer on Axion Physics

Annalen der Physik, Volume 536, Issue 1, January 2024.
A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.

Relativistic corrections to the pair Bc-meson production in e+e− annihilation

Nuclear Physics B, 2016
Relativistic corrections to the pair Bc-meson production in e+e−-annihilation are calculated. We investigate a production of pair pseudoscalar, vector and pseudoscalar+vector Bc-mesons in the leading order perturbative quantum chromodynamics and ...

Decay constants and form factors of s-wave and p-wave mesons in the covariant light-front quark model

, 2011
We reanalyze the decay constants of s-wave and p-wave mesons and D, B ->M form factors, where M represents a pseudoscalar meson, a vector meson, a scalar meson, or an axial vector meson within a covariant light-front quark model.

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.
