Study of charm mixing and CP violation with D0 → K±π∓π±π∓ decays
Journal of High Energy PhysicsA study of charm mixing and CP violation in D 0 → K ± π ∓ π ± π ∓ decays is performed using data collected by the LHCb experiment in proton-proton collisions from 2015 to 2018, corresponding to an integrated luminosity of 6 fb −1.

Weak decays of antitriplet charmed baryons from the perspective of flavor symmetry
Journal of High Energy Physics, 2023 In this work, we carry out a global fit for the two-body weak decays of antitriplet charmed baryons in both SU(3) respected and broken scenarios incorporating all the available data up to date. In the SU(3) irreducible representation approach (IRA), more

Possible anomalies in Higgs decay: charm-suppression and flavour-violation [PDF]
The European Physical Journal C, 2009 It is suggested that the Higgs boson may have a branching ratio into the $c \bar{c}$ mode suppressed by several orders of magnitude compared with conventional predictions and in addition some small but detectable flavour-violating modes such as $b \bar{s}$ and $τ\barμ$.

Generation of SU(3) sum rule for charmed baryon decay
Journal of High Energy Physics, 2022 Flavor SU(3) symmetry is a powerful tool to analyze charmed baryon decays. In this work, we propose an approach to generate SU(3) sum rules for the singly and doubly charmed baryon decays without writing the Wigner-Eckhart invariants explicitly. The SU(3)

Flavour-violating decays of mixed top-charm squarks at the LHC [PDF]
The European Physical Journal C, 2018 We explore signatures related to squark decays in the framework of non-minimally flavour-violating Supersymmetry. We consider a simplified model where the lightest squark consists of an admixture of charm and top flavour. By recasting the existing LHC searches for top and charm squarks, we show that the limits on squark masses from these analyses are ...

A U-spin anomaly in charm CP violation
Journal of High Energy Physics, 2023 Recent LHCb data shows that the direct CP asymmetries of the decay modes D 0 → π + π − and D 0 → K + K − have the same sign, violating an improved U-spin limit sum rule in an unexpected way at 2.1σ.

The mathematical structure of U-spin amplitude sum rules
Journal of High Energy Physics, 2022 We perform a systematic study of SU(2) flavor amplitude sum rules with particular emphasis on U-spin. This study reveals a rich mathematical structure underlying the sum rules that allows us to formulate an algorithm for deriving all U-spin amplitude sum
