213. Time-integrated WS-to-RS ratio of the 𝑫0 −→ 𝑲+𝝅−𝝅0 decay at Belle II / Chanchal Sharma, Kavita Lalwani [BELLE2-CONF-PROC-2023-047]
27 December 2023

In the standard model, mixing and CP violation in the charm sector are expected to be very small, and thus, they constitute a sensitive probe for potential new physics contributions. [...]
