Four-quark states with charm quarks in a two-body Bethe-Salpeter approach

Nico Santowsky, Christian S. Fischer

We study the internal structure of a range of four-quark states with charm quark contributions using a two-body Bethe-Salpeter equation. Thereby, we examine charmonium-like states…

The light scalars: four- vs. two-quark states in the complex energy plane from Bethe-Salpeter equations

Nico Santowsky, Christian S. Fischer

We study the dynamical generation of scalar mesons in the light quark sector ( $q \in {u, d, s}$ ) and calculate the masses and widths for the $f_{0} (500), a_{0} (980)$ and $f_{0} (980)$ . To th…

Reply to comment on "The $σ$ -meson: four-quark vs. two-quark components and decay width in a Bethe-Salpeter approach"

Nico Santowsky, Gernot Eichmann, Christian S. Fischer +2

In a recent comment [1] Blankleider and Kvinikhidze claim that our work [2] is based on a set of inconsistent Bethe-Salpeter equations for the coupling of four-quark to two-quark s…
