Measurement of CP asymmetry in D 0 → K S 0 K S 0 $$ {D}^0\to {K}_{\textrm{S}}^0{K}_{\textrm{S}}^0 $$ decays with Run 3 data

open access: yesJournal of High Energy Physics
A measurement of CP asymmetry in D 0 → K S 0 K S 0 $$ {D}^0\to {K}_{\textrm{S}}^0{K}_{\textrm{S}}^0 $$ decays is reported, based on a data sample of proton-proton collisions collected with the LHCb detector in 2024 at a centre-of-mass energy of 13.6 TeV,

Nonperturbative dynamics in D-meson mixing

open access: yesJournal of High Energy Physics
Theoretical predictions for the $${D}^{0}\overline{{D }^{0}}$$ mixing parameters fall significantly short of experimental measurements, with discrepancies spanning several orders of magnitude. This gap is mainly due to the Glashow-Iliopoulos-Maiani (GIM)

Neutrino nonstandard interactions and lepton flavor universality violation at SND@LHC via charm production

open access: yesJournal of High Energy Physics
In this work, we explore the effect of neutrino nonstandard interactions (NSI) involving the charm quark at SND@LHC. Using an effective description of new physics in terms of four-fermion operators involving a charm quark, we constrain the Wilson ...

Long distance contributions to neutral D-meson mixing from lattice QCD

open access: yesJournal of High Energy Physics
The study of neutral D-meson mixing provides a unique probe of long-distance effects in the charm sector, where Standard Model contributions are dominated by nonperturbative effects.

Search for charged-lepton flavour violation in top quark interactions with an up-type quark, a muon, and a τ lepton in proton-proton collisions at $$\sqrt{s}={13}$$ TeV

open access: yesJournal of High Energy Physics
A search for charged-lepton flavour violation (CLFV) in top quark (t) production and decay is presented. The search uses proton-proton collision data corresponding to 138 fb −1 collected with the CMS experiment at $$\sqrt{s}={13}$$ TeV.

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

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 ...

Measurements of T-odd observables

open access: yes, 2015
The study of T-odd observables using four-body hadronic final states of charm meson decays provides complementary insight to measuring CP asymmetries via decay rate asymmetries.
