The polarizations of promptly produced ${\ensuremath{\chi}}_{c1}$ and ${\ensuremath{\chi}}_{c2}$ mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$. The ${\ensuremath{\chi}}_{c}$ states are reconstructed via their radiative decays ${\ensuremath{\chi}}_{c}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\gamma}$, with the photons being …
