Description
In the present talk we will present results from a large data sample collected at 7 TeV, from which CMS could extensively study the polarization of the 3 Upsilon states, as a function of pT in two rapidity windows, conducting a complete analysis, including the polar and azimuthal anisotropy angles, and in 3 different polarization frames.
Thanks to the large data sample, CMS could also extensively study the polarization of the 3 Upsilon states, as a function of pT in two rapidity windows, conducting a complete analysis, including the polar and azimuthal anisotropy angles, and in 3 different polarization frames.
Given its powerful Silicon tracker, CMS has excellent photon conversion capabilitites, allowing to separately study the chic2 and chic1 P-wave states, separated by a mass difference of 45 MeV only.
