Current status of the E(1420)/{iota}(1440) and future prospects of the g{sub T} decaying into {phi}{phi}
A survey is given of the current status of the f{sub 1}(1420)/E and the {eta}(1440)/{iota} in the channels of K {bar K}{pi} and {eta}{pi}{pi}. There is now strong evidence that the {eta}(1440)/{iota} is split into two J{sup PC} = o{sup {minus}+} states in the 1.4--1.5 GeV range with the lower-mass state coupling mostly to a{sub 0}(980){pi} whereas the upper-mass state couples mainly to K*(890){bar K}. Both of them cannot be quarkonia. It appears very likely that the f{sub 1}(1420)/E is an S-wave K*(890){bar K} molecule with a strong overlap with the a{sub 0}(980)/{delta}. It is thought that one or more of the J{sup PC} = 1{sup ++} f{sub 2}(2010)/g{sub r}, F{sub 2}(2300)/g{sub T}{prime} and f{sub 2}(2340)/g{sub f}{double_prime} states decaying into {phi}{phi} may be the tensor glueball. The future prospects at BNL and elsewhere for further experimental work on these on other exotic states coupling to {phi}{phi} are discussed.
