Rare $B$ Decays as Tests of the Standard Model (2016, methodology): “Figure 13: Measurement of the ratios RD and RD∗ by the BaBar [263], Belle [264, 265] and LHCb [266] collaborations.”
Revisiting the one leptoquark solution to the R(D(∗)) anomalies and its phenomenological implications (2016, background): “However, the BaBar [6, 7], Belle [8, 9] and LHCb [10] collaborations have recently observed anomalies in the ratios R(D(∗)) = B(B̄ → D(∗)τ ν̄τ ) B(B̄ → D(∗)`ν̄`) , ` = e/µ .”
Phenomenology of an SU(2) × SU(2) × U(1) model with lepton-flavour non-universality (2016, methodology): “The latter includes R(D) and R(D∗) measurements performed by BaBar and Belle [119,120], the LHCb measurement of R(D∗) [121], and the independent Belle measurement of R(D∗) using a semileptonic tagging method [122].”
Maximal flavour violation: a Cabibbo mechanism for leptoquarks (2018, unknown): “One possible answer was given by the principle of Minimal Flavour Violation [1], which allowed for exciting NP at ATLAS and CMS while predicting less room for serendipity at LHCb.”
Beyond the Standard Model Physics at the HL-LHC and HE-LHC (2018, background): “Indeed, the ability of LHC experiments, with a leading role of LHCb in this context, to observe extremely rare flavour transitions, allows one to set constraints on new physics corresponding to scales of hundreds, or even thousands of TeV, completely inaccessible to direct searches.”
