Effective field theory analysis of rare |∆c| = |∆u| = 1 charm decays

open access: yesJournal of High Energy Physics
We perform a global analysis of |∆c| = |∆u| = 1 transitions using recent data on D 0 → μ + μ − , D + → π + μ + μ − , Λ c → p μ + μ − , and D 0 → π + π − μ + μ − decays, and work out constraints on new physics Wilson coefficients C 7 , 9 , 10 ′ $$ {C}_{7 ...

New predictions for the lifetimes of doubly heavy baryons and the B c meson

open access: yesJournal of High Energy Physics
We present updated predictions for the lifetimes of all weakly decaying doubly heavy baryons, including bb, cc, and bc baryons, as well as for the B c meson.

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 the LHCb Run 3 detector

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)

Study of doubly heavy baryon lifetimes

open access: yesJournal of High Energy Physics
We study the lifetimes and inclusive semileptonic decay widths of doubly heavy baryons within the framework of heavy quark expansion. Our analysis includes next-to-leading-order corrections to the dimension-3, -5, and -6 operators, together with the ...

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 ...
