Abstract: We analyze patterns from CP-violating new physics (NP) in hadronic and semileptonic rare charm $\vert \Delta c \vert=\vert \Delta u\vert=1$ transitions. Observation of direct CP-violation in hadronic decays, as in $\Delta A_{\text{CP}}$, provides opportunities for… read more here.

Abstract: We consider effects of coloured scalar mediators in decays c → u invisibles. In particular, in these processes, as invisibles, we consider massive right-handed fermions. The coloured scalar S̄1 ≡ (3̄, 1,−2/3), due to its… read more here.
