Using the expression of the dynamical gluon mass obtained through the operator product expansion we discuss the relevance of gluon mass effects in the decays V -> hadrons (V = J/Psi, Upsilon). Relativistic and radiative corrections are also introduced to calculate alpha_s(m_c) and alpha_s(m_b) comparing them with other values available in the literature. The effects of dynamical gluon masses are negligible for Upsilon decay but important for J/Psi decay.

Discussion (0). Continue with ORCID to comment.

  1. Nonrelativistic meson masses from the Curci-Ferrari model

    hep-ph 2025-09 conditional novelty 5.0 of 10

    A potential model built from the Curci-Ferrari massive-gluon action fits charm and bottom meson spectra, and the fit prefers a nonzero gluon mass.

  2. Gluon mass scale through the Schwinger mechanism

    hep-ph 2025-01 conditional novelty 2.0 of 10

    A comprehensive review showing how massless composite poles in QCD vertices can generate the gluon mass scale, with a BSE-based computation reaching m=367 MeV against the 354 MeV lattice value.
