**Title:**
Recent results on the search of direct CP violation in
K^{+-} -> 3 pi decays by the NA48/2 Collaboration

**Speaker:** Dr Luca Fiorini (Cambridge)

**Abstract**

NA48/2 is a high precision
experiment on charged Kaon decays installed at SPS site of CERN and using a
novel design for simultaneous
K^{+}/K^{-} beams and an upgraded NA48 set-up.
Main goal of the experiment is the search of direct CP-violation in
K^{+-} -> 3 pi
decays. During the two years long data taking, an unprecedentedly large
statistics of
K^{+-}
decays has been collected.
Recent results on direct CP violation obtained by
the analysis of 2003 data will be presented.
The observation of a cusp-like effect in the
pi^{+-} pi^{0} pi^{0}
Dalitz plot and a linked novel method to measure the difference of
pion-pion scattering lengths
a_{0}-a_{2}
will be presented as well.
