In recent years, the CKM picture of flavor and CP violation has been confirmed, mainly due to B decay data. Yet, it is likely that there are small corrections to this picture. We expect to find new physics not much above the weak scale.…

With the first evidence of direct CP violation in $D^0 \to K^+K^-/\pi^+\pi^-$ there is a strong reason to probe CP asymmetries in charm baryons in three-body final states $\Lambda_c \to p\pi^+\pi^-/pK^+K^-$ & $\Lambda_c \to pK^+\pi^-$ with…
