Abstract
The polarization of photons produced in radiative decays is studied for the first time. The data are recorded by the LHCb experiment in collisions corresponding to an integrated luminosity of at center-of-mass energies of 7 and 8 TeV. A time-dependent analysis of the decay rate is conducted to determine the parameter , which is related to the ratio of right- over left-handed photon polarization amplitudes in transitions. A value of is measured. This result is consistent with the standard model prediction within 2 standard deviations.
