We measure five angular-asymmetry observables as functions of the decay recoil that are sensitive to lepton-universality-violating contributions. We use events where one neutral $B$ is fully reconstructed in $\\Upsilon\\left(4S\\right)\\to{}B\\overline{B}$ decays in data corresponding to $189~\\mathrm{fb}^{-1}$ integrated luminosity from electron-positron collisions collected with the Belle II detector. We find no significant deviation from the standard model expectations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.144759.v1/t1","@type":"Dataset","description":"Observed values of all angular asymmetry variables.","name":"Central values"},{"@id":"https://doi.org/10.17182/hepdata.144759.v1/t2","@type":"Dataset","description":"Full experimental covariance matrix of all angular asymmetry variables.","name":"Covariance Matrix"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2685572?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/144759"}],"inLanguage":"en","name":"Tests of light-lepton universality in angular asymmetries of $B^0 \\to D^{*-} \\ell \\nu$ decays","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2685572?version=1","version":1}
