Vector meson production, pion photoproduction, and vector meson dominance

open access: yesNuclear Physics B, 1971
Abstract The vector meson dominance hypothesis can be formulated covariantly in terms of invariant amplitudes. This method, which has been successfully used to predict π−p→ϱon from pion photoproduction, is extended to include ω production and charged ϱ production. With the introduction of only two further parameters to describe the mass dependence of

The electromagnetic form factors of heavy-light pseudo-scalar and vector mesons

open access: yesJournal of High Energy Physics
We systematically investigate the electromagnetic form factors of heavy-light pseudo-scalar and vector mesons within the Dyson-Schwinger/Bethe-Salpeter equations framework for the first time.

X(3872): propagating in a dense medium

open access: yesNuclear Physics B, 2018
In cold nuclear matter, the shifts in the mass and current-meson coupling as well the vector self energy of the exotic X(3872) are calculated using the diquark–antidiquark current within the framework of the in-medium two-point QCD sum rule.
