In the Standard Model, the three charged leptons are identical copies of each other, apart from mass differences. Experimental tests of this feature in semileptonic decays of b-hadrons are highly sensitive to New Physics particles which preferentially couple to the 2nd and 3rd generations of leptons. A review of the latest lepton universality tests in semileptonic $b\to c$ transitions at LHCb is reported.

Anonymous Report 1 on 2019-1-17 Invited Report


The provided proceedings give a very clear overview on measurements on lepton flavour non-universality at LHCb. The content is certainly worth to publish. A few minor comments of editorial nature have been provided to the author and are requested to be included.

Requested changes

2nd paragraph first sentence: tau leptons is a challenging at -> either is a challenge or is challenging
2nd paragraph towards the end: “selmileptonic" -> “semilleptonic"; "Run 1 data collected by LHC experiment" -> either "by the LHCb experiment” or “by LHCb”


Sentence after Eq (1): missing comma before respectively
End of next paragraph: missing comma after “(describing the separation of signal decay particles from other decays)”
End of this section: “smallest smallest” -> smallest

“at the time or writing” -> “at the time of writing"
