KLOE results

• KLOE has published about 50 physics papers, addressing several fundamental topics in the fields of flavour and hadronic physics. Among the results the two main ones are:

– The complete set of measurement of neutral and charged kaon decay parameters to allow the precision measurement of Vus setting the best unitarity limit on the CKM matrix

– New preliminary result on hadronic contribution to muon g-2, confirming previous 3 discrepancy between theory and experiment

Limit on “dark photon” production

• Limit on “dark photon” production set using → ee decays

• Best limit in the mass range 40 < MU < 400 MeV

– Start of machine/detector debugging : August/September 2013

– Start of physics data taking: fall 2013

– Goal of integrating 5 fb1 within 2 years

• Main physics goals – Precision kaon quantum interferometry

– Rare KS and decays

– Two photon physics with tagged electrons/positrons

– Searches for dark photons
