Özet
.Understanding the internal structure of the scalar mesons has been a prominent topic in the last decades.
Although the scalar mesons have been investigated both theoretically and experimentally, however, many
properties of them are not so clear yet. Identifying the scalar mesons is difficult, experimentally; hence the
theoretical and phenomenological works can play a crucial role in this respect. In this work, the decay constant and
mass of all light scalar mesons are evaluated in the context of the two-point QCD sum rules. The results on masses
and decay constants are in good consistency with existing experimental data. Our predictions for those which we
have not any experimental results yet can be checked in future experiments.
