Squark flavour violation and naturalness at the LHC [PDF]
, 2013 While rare meson decays place stringent constraints on much of the flavour violating parameter space of supersymmetric models, the mixing between right-handed top and charm squarks is so far unconstrained by the available data.

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 +

Searches for CP violation in two-body charm decays [PDF]
, 2015 where the first uncertainty is statistical and the second systematic. This represents a significant improvement in precision over the previous measurement of this parameter.

CP violation in charm and beauty decays at LHCb [PDF]
, 2013 LHCb is a dedicated heavy flavour physics precision experiment at the LHC searching for New Physics (NP) beyond the Standard Model (SM) through the study of very rare decays of beauty and charm-flavoured hadrons and precision measurements of CP-violating

A bound on the charm chromo-EDM and its implications [PDF]
Journal of High Energy Physics, 2013 A bstractWe derive bounds on the electric and chromo-electric dipole moments of the charm quark. The second one turns out to be particularly strong, and we quantify its impact on models that allow for a sizeable flavour violation in the up quark sector ...

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.

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.

Tasting flavoured Majorana dark matter
Journal of High Energy Physics, 2022 We study a simplified model of flavoured Majorana dark matter in the Dark Minimal Flavour Violation framework. The model extends the Standard Model by a dark matter flavour triplet and a scalar mediator, through which the new dark fermions couple to ...

Study of singly heavy baryon lifetimes
Journal of High Energy Physics, 2023 We study the inclusive decay widths of singly heavy baryons with the improved bag model in which the unwanted center-of-mass motion is removed. Additional insight is gained by comparing the charmed and bottom baryons. We discuss the running of the baryon
