Revisiting lifetimes of doubly charmed baryons

open access: yesJournal 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 +

Lifetimes of singly charmed hadrons

open access: yesJournal of High Energy Physics, 2022
We provide an extensive study of the lifetimes of singly charmed baryons and mesons, within the heavy quark expansion with all known corrections included.

Open Charm Physics at BESIII [PDF]

open access: yesEPJ 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.

A novel unbinned model-independent method to measure the CKM angle γ in B ± → DK ± decays with optimised precision

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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

Simple model for large CP violation in charm decays, B-physics anomalies, muon g − 2 and dark matter

open access: yesJournal 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 ...

Measurement of CP asymmetries in D s + → η π + $$ {D}_{(s)}^{+}\to \eta {\pi}^{+} $$ and D s + → η ′ π + $$ {D}_{(s)}^{+}\to {\eta}^{\prime }{\pi}^{+} $$ decays

open access: yesJournal of High Energy Physics, 2023
Searches for CP violation in the decays D s + → η π + $$ {D}_{(s)}^{+}\to \eta {\pi}^{+} $$ and D s + → η ′ π + $$ {D}_{(s)}^{+}\to {\eta}^{\prime }{\pi}^{+} $$ are performed using pp collision data corresponding to 6 fb −1 of integrated luminosity ...

Mixing and CP violation in the beauty and charm sectors at LHCb

open access: yesEPJ Web of Conferences, 2014
The LHCb detector is a dedicated heavy flavour experiment operating at the Large Hadron Collider designed to pursue an extensive study of CP violation in the beauty and charm sectors.
