# Aspects of open-flavour mesons in a comprehensive DSBSE study

## TL;DR

This paper extends Dyson-Schwinger-Bethe-Salpeter-equation studies to all open-flavour mesons, providing comprehensive theoretical results for meson masses and decay constants compared with experimental data and other models.

## Contribution

It offers the most extensive set of open-flavour meson results within the DSBSE framework, covering all flavour combinations and benchmarking against existing data.

## Key findings

- Comprehensive meson mass predictions across all flavour combinations.
- Leptonic decay constants calculated and compared with experimental values.
- Results align well with other theoretical approaches and experimental data.

## Abstract

Open-flavour meson studies are the necessary completion to any comprehensive investigation of quarkonia. We extend recent studies of quarkonia in the Dyson-Schwinger-Bethe-Salpeter-equation approach to explore their results for all possible flavour combinations. Within the inherent limitations of the setup, we present the most comprehensive results for meson masses and leptonic decay constants currently available and put them in perspective with respect to experiment and other approaches.
