Measurement of W-Polarization in Di-Leptonic ttbart Events in pp Collisions with sqrt(s) = 7 TeV
We present a measurement of the W boson helicity fractions in $t\bar{t}$ events with the full dataset collected by the CMS detector in 2011 at a center-of-mass energy of $\sqrt{s}=7$~TeV. This corresponds to an integrated luminosity of $4.6\;\mathrm{fb}^{-1}$. The analysis is based on the dilepton d...
