Abstract
A measurement of the time-integrated CP asymmetry in D 0→ K 0 S K 0 S 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 D 0 candidate is required to originate from a D*+→ D 0 π+ decay, allowing the determination of the flavour of the D 0 meson using the pion charge. The D 0→ K+ K− decay, which has a well measured CP asymmetry, is used as a calibration channel. The CP asymmetryfor D 0→ K 0 S K 0 S is measured to be
