We present Monte Carlo preliminary results about the feasibility to detect the χ c family in p-p collisions at 14 TeV in the ALICE Central Barrel at CERN LHC. The χ c1 and χ c2 were forced to decay in the radiative channel J/Ψ+γ→e + e −+γ and were merged with a proton-proton non-biased collision. After Monte Carlo transport and simulation of the detector response, the e +, e − and converted γ were reconstructed and identified in the ALICE ITS, TPC and TRD detectors. Separate signals corresponding to γ from χ c1 and from χ c2 were observed. The position and relative weight of the fit to gaussians agreed with the input values within the statistical limits.
