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

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 ...

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.

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.

The charm of 331 [PDF]

open access: yesJournal of High Energy Physics, 2021
We perform a detailed analysis of flavour changing neutral current processes in the charm sector in the context of 331 models. As pointed out recently, in the case of Z′ contributions in these models there are no new free parameters beyond those already ...

A search for top-squark pair production, in final states containing a top quark, a charm quark and missing transverse momentum, using the 139 fb −1 of pp collision data collected by the ATLAS detector [PDF]

open access: yesJournal of High Energy Physics
This paper presents a search for top-squark pair production in final states with a top quark, a charm quark and missing transverse momentum. The data were collected with the ATLAS detector during LHC Run 2 and correspond to an integrated luminosity of ...

CP Violation in Heavy-Flavour Hadrons [PDF]

open access: yesLepton Photon Interactions at High Energies, 2017
Measurements of $CP$-violating observables in $B$ meson decays can be used to determine the angles of the Unitarity Triangle and hence probe for manifestations of New Physics beyond the Cabibbo-Kobayashi-Maskawa Standard Model paradigm.

SM prediction for the CP asymmetries in two-body hadronic charm meson decays

open access: yesProceedings of 21st Conference on Flavor Physics and CP Violation — PoS(FPCP2023), 2023
Charm Physics is highly topical in the current flavour landscape, especially after the announcement by LHCb of the measurement of direct CP asymmetries in the separate decays of 𝐷 0 → 𝐾 + 𝐾 − and consequently 𝐷 0 → 𝜋 + 𝜋 − , preceded by the measurement ...

CKM, mixing and $CP$ violation results at LHCb

open access: yesProceedings of Particles and Nuclei International Conference 2021 — PoS(PANIC2021), 2022
We review the most precise tests of the CKM model of flavour physics performed by the LHCb collaboration during 2021. These include world best measurements of both time-dependent and time-independent CP violation in charm decays, the first observation of
