Abstract
Nucleon-antinucleon (N \(\bar N\)) annihilation reactions provide a copious source for the production of gluons (g) through the destruction of quark-antiquark (Q \(\bar Q\)) pairs in the initial state. Therefore, in addition to the production of the usual Q \(\bar Q\) meson states, N \(\bar N\) annihilation can serve as an entrance channel to mesonic resonances containing dynamical excitations of the gluon field, for instance hybrids (Q \(\bar Q\) g). We discuss the main features of the spectrum and decay modes for these hybrid mesons. Particularly, we focus on the production mechanism in N \(\bar N\) annihilation, thereby employing a microscopic model with constituent quarks and gluons. The interpretation of the E(1420), observed in the reaction \(p\bar p \to \pi ^ + \pi ^ - E\) at rest, as a hybrid meson is investigated.
