Results of the coupled channel analysis of π+π−π0, K+K−π0 and K±K0Sπ∓ final states from p̄p annihilation at rest in hydrogen targets at different densities
2003
Abstract The π + π − π 0 , K + K − π 0 and K ± K 0 π ∓ final states produced by p p annihilation at rest at three different hydrogen target densities have been analyzed in the frame of a coupled channel analysis together with ππ and πK scattering data. Here we present the main results which concern masses, widths, ππ and K K partial widths of all the involved resonances ( J P =0 + ,1 − ,2 + ), the direct determination of Γ K K /Γ ππ ratio for f 0 (1370) and f 0 (1500) ( Γ K K /Γ ππ =0.91±0.20 and Γ K K /Γ ππ =0.25±0.03 , respectively), the determination of a 0 (1300) parameters ( M =1303±16 MeV; Γ =92±16 MeV) and the observation of two different high mass ρ signals associated to ρ (1450) and ρ (1700) ( M =1182±30 MeV; Γ =389±20 MeV and M =1594±20 MeV; Γ =259±20 MeV, respectively).
