Measurements of the production of P-wave charmonium states through radiative decays at the ATLAS experiment
he production cross sections of the χc1 and χc2 charmonium states are\nmeasured in\npp collisions at √s = 7 TeV using 4.5 fb−1 of integrated luminosity\nrecorded by the\nATLAS detector at the LHC. The χc states are reconstructed in the radiative\ndecay\nχc → J/ψ(μ+μ−)γ, where the photons are reconst...
