Abstract
We present experimental evidence for the existence of the decay ψ(3684)→γχ, χ→4π±, 6π±, π+π-K+K-, π+π-, and K+K-. There is clear evidence for at least two χ states, one at 3.41 ± 0.01 GeV/c2 and the other at 3.53±0.02 GeV/c2. The χ(3410) decays into ππ and KK and thus must have even spin and parity.
