SU(5) symmetry?
Krasnikov N.V. , Kuz'min V.A.
It is suggested that the recently discovered particles ψι(3105) and ψ2(3695) are members of a 25-plet of vector mesons within the framework of the 5(7(5) groups. The masses of the /" and 0" mesons in the lowest multiplets of the SU(5) group are calculated.
