Amplitude analysis of the B+→D+D−K+ decay

Roel Aaij, +973 more
- 07 Dec 2020 - 
TL;DR: In this paper, an amplitude analysis of the LHCb proton-proton collision data was carried out using LHC b collision data taken at 7,8,$ and 13$ TeV, corresponding to a total integrated luminosity of 9 fb$^{-1}.

Test of lepton universality in beauty-quark decays

Roel Aaij, +956 more
- 22 Mar 2021 - 
TL;DR: In this paper, the authors present evidence for the breaking of lepton universality in beauty-quark decays, with a significance of 3.1 standard deviations, based on proton-proton collision data collected with the LHCb detector at CERN's Large Hadron Collider.
