$\Upsilon(nS)$ polarizations in $pp$ collisions at $\sqrt{s}=$ 7 and 8 TeV by the LHCb collaboration
A polarization measurement carried out for the $\Upsilon(1S)$, $\Upsilon(2S)$ and $\Upsilon(3S)$ mesons produced in pp collisions at $\sqrt{s}=$ 7 and 8 TeV is presented. Data samples used for the polarization measurement were collected by the LHCb experiment during the 2011 and 2012 data taking run...
