their decays into m++ m+ m. Apparently they are produced onlyin the T= O channel. The &
meson has been assigned spinand parity 1 on the basis of good agreement with a Dalitz …

With the tentative choice of G&&4*= iC $ &4rr and r (6” 2n)= 10 MeV, the contribution from
the C-meson pole turns out to be only about 25% of the contribution from the p-meson pole …

&u (q) meson into two charged particles: e++ e, p,++ p,, and m++ m In particular we point out
that the m+ m mode of the co meson, which involves (,—,'-,) twice in the decay rate, may turn …

The branching ratios of the decay of the η 0 meson into neutral products have been
measured. The η 0 is produced in the reaction π− p→ η 0+ n, and the decay products are …

'HE decay of the chargedm-meson throughvirtual nucleon pairs and the annihilation of a pair
with the creation of a neutrino and an electron or p-meson is permitted by the accepted …

(4) u and v are the appropriate spinors for the negative and positive muons or electrons with
mo-menta P and P, q is the rl momentum, k the photon momentum, and e the polarization …

FIG. l. In addition to the three meson nonets, with J= 0, 1, and 2+, which are discussed in the
text, 16 possible candidates for J+= 1 assignments are shown. These are A~(1090), B …

Various assignments of spin J, parity I', and G parity (denotedby 8+ G) for the q have been
dis-cussed by several authors"'; the most popular are the 0+ assignment corresponding to …

The experiment described in the previous I etter'also yields information on thedecay
products of the cv and q mesons.% e present here studies on correlations among the decay …

However, any I= 0 configuration of three pions must be antisymmetric in all pairs of pions.
The original data were insufficient to make this test, but Bastien et al. later reported …
