Spin properties in W->taunu events
A measurement of tau polarization in W→τν decays is presented. It is measured from the energies of the decay products in hadronic τ decays with a single final state charged particle. The measured value of the τ polarization is P τ =−1.06±0.04(stat) +0.05 −0.07 (syst) , in agreement with the Standard...

| description | A measurement of tau polarization in W→τν decays is presented. It is measured from the energies of the decay products in hadronic τ decays with a single final state charged particle. The measured value of the τ polarization is P τ =−1.06±0.04(stat) +0.05 −0.07 (syst) , in agreement with the Standard Model prediction, and is consistent with a physically allowed 95% CL interval [-1,-0.91]. |
