Current status of the E(1420)/ι(1440) and future prospects of the gT decaying into φφ
Description
A survey is given of the current status of the f1(1420)/E and the η(1440)/ι in the channels of K bar Kπ and ηππ. There is now strong evidence that the η(1440)/ι is split into two JPC = o-+ states in the 1.4--1.5 GeV range with the lower-mass state coupling mostly to a0(980)π whereas the upper-mass state couples mainly to K*(890)bar K. Both of them cannot be quarkonia. It appears very likely that the f1(1420)/E is an S-wave K*(890)bar K molecule with a strong overlap with the a0(980)/δ. It is thought that one or more of the JPC = 1++ f2(2010)/gr, F2(2300)/gT' and f2(2340)/gf double-prime states decaying into φφ may be the tensor glueball. The future prospects at BNL and elsewhere for further experimental work on these on other exotic states coupling to φφ are discussed
