Simple model for large CP violation in charm decays, B-physics anomalies, muon g − 2 and dark matter
Journal of High Energy Physics, 2020 We present a minimal extension of the Standard Model that can simultaneously account for the anomalies in semi-leptonic B meson decays and the muon g − 2, give large CP violation in charm decays (up to the value recently measured by LHCb), and provide ...

Revisiting lifetimes of doubly charmed baryons
Journal of High Energy Physics, 2023 We present updated predictions for lifetimes of doubly charmed baryons, within the heavy quark expansion, including available NLO α s contributions and newly-computed terms in the 1/m c series. Our improved results confirm the expected hierarchy τ Ξ cc +

Open Charm Physics at BESIII [PDF]
EPJ Web of Conferences, 2019 The study of mesons and baryons containing at least one c quark is denoted as open charm physics. BESIII has collected large data samples at charm related thresholds which provide unique opportunities to study charm decays.

Journal of High Energy Physics, 2023 We present a novel unbinned method to combine B ± → DK ± and charm threshold data for the amplitude-model unbiased measurement of the CKM angle γ in cases where the D meson decays to a three-body final state.

Supersymmetric QCD flavor changing top quark decay [PDF]
, 1997 We present a detailed and complete calculation of the gluino and scalar quarks contribution to the flavour-changing top quark decay into a charm quark and a photon, gluon, or a Z boson within the minimal supersymmetric standard model including flavour ...

Isospin symmetry and analyticity in D → K ¯ ππ $$ D\to \overline{K}\pi \pi $$ decays
Journal of High Energy Physics, 2023 We perform a detailed study of the consequences of isospin symmetry in the Cabibbo favoured D → K ¯ ππ $$ D\to \overline{K}\pi \pi $$ decays. These processes are important for precision testing of the Standard Model and for hadronic physics.
