ρ-ω mixing in J/ψ → VP decays

Abstract

Abstract:The study of ρ-ω mixing has mainly focused on vector meson decays with isospin I = 1, namely the ρ(ω) → π + π − process. In this paper, we present a study of ρ-ω mixing in ρ(ω) → π + π − π 0 (I = 0) using a flavor parameterization model for the J/ψ → VP process. By fitting a theoretical framework to PDG data, we obtain the SU(3)-breaking effect parameters sV = 0.03±0.12, sP = 0.17±0.17 and the ρ-ω mixing polarization operator Πρω = (0.006±0.011) GeV 2 . New values are found for the branching ratios when the mixing effect is incorporated:

“…Besides, the crystallinity before crosslinking of 6s-PCL 100 , 6-s-PCL 200 , and 6-s-PCL 300 were 48.5%, 50.0%, and 50.7%, which have been reported in our previous study. 44 However, the crystallinity of PCL segment in the APCNs was far different from it. For APCNs (PCL200-PEG) and APCN (PCL300-PEG) , there were 12.64% and 13.71% respectively.…”
