Spin-dependent Effects on the Hyperfine Structure in Heavy Hybrid Mesons

Abstract

We study the hyperfine structure of a heavy hybrid meson, interesting because of the non-trivial contribution of its gluon field on the heavy quak-antiquark pair. We will be able to work on a non-relativistic frame, thanks to the meson being much heavier than the energy of the gluonic field, and so use the Schrödinger equation to define the system. With the results from the hyperfine structure we will be able to draw the relationships between the different possible masses of the system
