E835 studied the properties of the charmonium states formed in pp̄ annihilations. Recent and preliminary results are presented, including new preliminary measurements of χ cJ masses and widths (improving the knowledge of fine splitting of P states), a preliminary measurement of ψ(2S) branching ratios, and of the two photon partial width of the χ c 0 .

Abstract
E835 studied the properties of the charmonium states formed in pp̄ annihilations. Recent and preliminary results are presented, including new preliminary measurements of χ cJ masses and widths (improving the knowledge of fine splitting of P states), a preliminary measurement of ψ(2S) branching ratios, and of the two photon partial width of the χ c 0 .
