Rare Charm Decays at BESIII (2403.11597v1)

Published 18 Mar 2024 in hep-ex and hep-ph

Abstract: The rare and forbidden processes within the Standard Model offer an opportunity to explore potential new physics beyond the SM. We summarize the research method and the recent results of rare charm decays at BESIII based on the extensive data samples in the $\tau-c$ energy region, many of which impose stringent constraints on the new physics.
