DESCRIPTION:Speakers: Giulia Tuci (Heidelberg University)\n\nMeasurement o
 f CP asymmetry in D0→K0SK0S decays with the upgraded LHCb detector \nTh
 e study of CP violation in charm mesons provides a complementary probe for
  possible interactions beyond the Standard Model with respect to beauty me
 sons\, and allows the exploration of even higher energy scales. The LHCb e
 xperiment collected the largest sample of charm hadrons ever\, order of bi
 llions of decays\, and reported the first observation of CP violation in D
 0→K+K- and D0→ π + π  π - decays in 2019\, marking a milestone in
  flavour physics.  However\, the compatibility of the observation with th
 e Standard Model is still debated\, and providing complementary experiment
 al results is a crucial step towards clarifying the physics picture. In th
 is seminar\, a new measurement of the time-integrated CP asymmetry in the 
 decay D0->KsKs will be presented. The analysis has been performed using da
 ta collected by the LHCb experiment in 2024. The analysis is based on data
  collected by the LHCb experiment in 2024\, using the upgraded detector wi
 th improved tracking\, vertex resolution\, and a software-based trigger sy
 stem. Thanks to these improvements\, unprecedented precision in charm phys
 ics can now be achieved.\n \n\nhttps://agenda.infn.it/event/49345/
