In this talk, we review the recent theoretical progress towards a precise determination of some hadronic observables such as the Kpi and pipi form factors. We show that significant improvement can be achieved by combining dispersive techniques with chiral perturbation theory calculations, lattice results and experimental measurements. We will then present two applications for precise tests of...

I give an overview of the Jefferson Lab Physics Analysis Center (JPAC) activities.
JPAC is a join center between Indiana University and the Jefferson Laboratory.
We provide theoretical tools for data analysis in hadron spectroscopy.
In this talk, I will present the following topics:
- Dalitz plot analysis of eta-> 3pi and omega-> 3pi
- omega -> pi gamma transition form factor
-...

The dispersive approach to QCD, which extends the applicability
range of perturbation theory towards the infrared domain, is
developed. This approach properly accounts for the intrinsically
nonperturbative constraints, which originate in the low-energy
kinematic restrictions on pertinent strong interaction processes.
The dispersive approach proves to be capable of describing
recently...

Formulation of confinement is discussed in the framework of general principles of q.f.t.
Characteristic space-time scales which define the bulk of high-energy hadron scattering
are derived.

Recently reparameterized $f_0(500)$ (former $\sigma$) meson became subject of a number of innovative works in QCD physics.
Difficult to find and to determine experimentally after many years of failures has been finally precisely described be means of theoretical dispersion relations with imposed crossing symmetry condition [1,2].
Its fundamental importance for low energy QCD opened up the...
