Riassunto
CP violation in charm has non yet been observed. The D0 -> KS0 KS0 decay is a promising discovery channel for CP violation in charm, because amplitudes are suppressed, a prediction based on Standard Model gives an upper limit for CP asymmetry of 1.1% (C.L. 95%) and further enhancements could result from contributions from physics beyond the Standard Model. I have performed a measurement of CP asymmetries in prompt D0 -> KS0 KS0 decays, using data collected with LHCb experiment in 2015 and 2016 at a 13 TeV pp center-of-mass energy (Run-2) and improving the sensitivity obtained in Run-1.
