Measurement of the polarization of the Υ(1S) and Υ(2S) states in pp̄ collisions at s=1.96TeV

Measurement of the polarization of the Υ(1S) and Υ(2S) states in pp̄ collisions at s=1.96TeV

We present a study of the polarization of the Υ(1S) and Υ(2S) states using a 1.3fb-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=(σT-2σL)/(σT+2σL), where σT and σL are the transversely and longitudin...
