dc.description.abstractA measurement of the time-integrated CP asymmetry in D0 → K0SK0S decays is reported. The data correspond to an integrated luminosity of about 2 fb−1 collected in 2015–2016 by the LHCb collaboration in pp collisions at a centre-of-mass energy of 13 TeV. The D0 candidate is required to originate from a D*+ → D0π+ decay, allowing the determination of the flavour of the D0 meson using the pion charge. The D0 → K+K− decay, which has a well measured CP asymmetry, is used as a calibration channel. The CP asymmetryfor D0 → K 0SK 0S is measured to be ACP(D0→K0SK0S)=(4.3±3.4±1.0)%, where the first uncertainty is statistical and the second is systematic. This result is combined with the previous LHCb measurement at lower centre-of-mass energies to obtain ACP(D0→K0SK0S)=(2.3±2.8±0.9)%.
