Measurement of the photon polarization in $Λ_{b} \to Λ γ$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +994

The photon polarization in $b \to s γ$ transitions is measured for the first time in radiative b-baryon decays exploiting the unique spin structure of $Λ_{b} \to Λ γ$ decays. A data s…
