 +   <​hidden TTP02-04 ​ QCD-corrected spin analysing power of jets in decays of polarized top quarks > We present results for the differential distributions of  
 + jets from non-leptonic decays of polarized 
 + top quarks within the Standard Model, including QCD radiative 
 + ​corrections. Our work extends existing results 
 + which are only available for semileptonic top quark  
 + ​decays at the parton level.  
 + For $t(\uparrow)\to b$-jet $+2$ light jets  
 + we compute in particular the QCD-corrected top-spin 
 + ​analysing power of the $b$-quark jet and the least energetic 
 + light jet. The dependence of the results on the choice 
 + of the jet recombination scheme is found to be small. 
 + In addition we compute the spin analysing 
 + power of the thrust axis. Our results constitute a so far  
 + ​missing ingredient to analyse top quark production and  
 + ​subsequent non-leptonic decay at next-to-leading order in $\alpha_s$, keeping 
 + the full information on the top quark polarization.
