| 英文摘要 | The polarization of photons produced in radiative b-s(0) decays is studied for the first time. the data are recorded by the lhcb experiment in pp collisions corresponding to an integrated luminosity of 3 fb(-1) at center-of-mass energies of 7 and 8 tev. a time-dependent analysis of the b-s(0) ->phi gamma decay rate is conducted to determine the parameter a(delta), which is related to the ratio of right-over left-handed photon polarization amplitudes in b -> s gamma transitions. a value of a(delta) = -0.98(-0.52)(-0.20)(+0.46)(+0.23) is measured. this result is consistent with the standard model prediction within 2 standard deviations. |
