The pion-pion scattering lengths from DIRAC

Cibran Santamarina

The scattering lengths of a two pion system are the {\it golden magnitudes} to test the QCD predictions in the low energy sector. The DIRAC (PS-212) experiment at CERN will obtain…

A Monte Carlo Calculation of the Pionium Break-up Probability with Different Sets of Pionium Target Cross Sections

C. Santamarina, M. Schumann, L. G. Afanasyev +1

Chiral Perturbation Theory predicts the lifetime of pionium, a hydrogen-like $π^{+} π^{-}$ atom, to better than 3% precision. The goal of the DIRAC experiment at CERN is to obtain and…
