| dc.description | We present a study of the polarization of the $Υ(1S)$ and $Υ(2S)$ states using a $1.3 $ fb$^{-1}$ data sample collected by the D0 experiment in 2002--2006 during Run II of the Fermilab Tevatron Collider. We measure the polarization parameter $α=(σ_{T}-2σ_{L})/(σ_{T}+2σ_{L})$, where $σ_{T}$ and $σ_{L}$ are the transversely and longitudinally polarized components of the production cross section, as a function of the transverse momentum ($p_{T}^Υ$) for the $Υ(1S)$ and $Υ(2S)$. Significant $p_{T}^Υ$-dependent longitudinal polarization is observed for the $Υ(1S)$. A comparison with theoretical models is presented. | |
