The International School for Advanced Studies (SISSA) was founded in 1978 and was the first institution in Italy to promote post-graduate courses leading to a Doctor Philosophiae (or PhD) degree. A centre of excellence among Italian and international universities, the school has around 65 teachers, 100 post docs and 245 PhD students, and is located in Trieste, in a campus of more than 10 hectares with wonderful views over the Gulf of Trieste.
SISSA hosts a very high-ranking, large and multidisciplinary scientific research output. The scientific papers produced by its researchers are published in high impact factor, well-known international journals, and in many cases in the world's most prestigious scientific journals such as Nature and Science. Over 900 students have so far started their careers in the field of mathematics, physics and neuroscience research at SISSA.

We have studied, with the KLOE detector at the DAΦNE Φ-Factory, the dynamics of
the decay η → π+π−π0 using η mesons from the decay ϕ → ηγ for an integrated luminosity = 450 pb−1.
From a fit to the Dalitz plot density distribution we obtain a precise measurement of the slope parameters.
An alternative parametrization relates the π+π−π0 slopes to that for η → 3π0 showing the consistency of KLOE results for both channels.
We also obtain the best confirmation of the C-invariance in the
η → π+π−π0 decay.
