Investigating the η1′(1855) exotic state in the J/ψ→η1′(1855)η(′) decays
An analysis of the J/ψ→ηη′γ decay by the BESIII collaboration claims the observation of an exotic state η1(1855) with IGJPC=0+1−+. To establish its C-parity partner η1′(1855) in the picture of the KK¯1(1400) molecular state, we propose that J/ψ→η1′(1855)η(′) receives the main contributions from the...
