            psi' and J/psi -->omega pi+pi-; omega f_2  (continued)

RESULTS:

            ----omega pi+pi- branching ratio----

Figure 3 shows a fit to the M(pi+pi-pi0) distribution of Fig. 1a (ie the 
J/psi sample).  The fit gives 364.9 +/- 27.4 J/psi-->omega pi+pi- events.

Figure 4 shows a fit to the M(pi+pi-pi0) distribution of Fig. 2a (ie the
psi' sample). The fit gives 203.2 +/- 19.6 J/psi-->omega pi+pi- events.

Thus, using the formula on Slide 2, we get:
 
      Br(psi'-->omega pi+pi-)          203.2+/-19.6
      ----------------------- = 0.19 x ------------ = 0.106 +/- 0.0013
      Br(J/psi-->omega pi+pi-)         364.9+/-27.4

Using the PDG value of Br(J/psi-->omega pi+pi-) = (7.2 +/- 1.0) x 10^{-3},
we get:

       **********************************************************
       *   Br(psi'-->omega pi+pi-) = (7.6 +/- 1.4) x 10^{-4}    *
       **********************************************************

This is larger then, but consistent with the Xinhua's result of
(5.6 +/- 1.4) x 10^{-4},

            ----omega f_2 branching ratio----


Figures 4 and 6 show fits to the M(pi+pi-) distribution of Fig. 1b (ie the 
J/psi sample) for different background shapes.  The fits give 208.8 +/- 23.7
J/psi-->omega f_2 events for a shape that seems to overestimate the back-
ground (Fig.5) and 290 +/- 33.7 for a shape that tries to minimize the
background.  I take the average of these as the number of J/psi->omega
f_2 events.

Figure 7 shows a fit to the M(pi+pi-) distribution of Fig. 2b (ie the
psi' sample). This fit, which gives 24 +/- 17 psi'-->omega f_2 events,
gives the most events of the various background shapes I tried.  Since
a fit without any f_2 gives a similar confidence level, I use this result
to establish a 90% CL upper limit of 45 for the number of psi'->omega f_2 
events.

Thus, using the formula on Slide 2, we get:
 
      Br(psi'-->omega f_2)             45
      --------------------- < 0.19 x ------ = 0.034
      Br(J/psi-->omega F_2)           250

Using the PDG value of Br(J/psi-->omega f_2) = (4.3 +/- 0.6) x 10^{-3},
we get:

       *********************************************
       *   Br(psi'-->omega f_2) < 1.4 x 10^{-4}    *
       *********************************************

This is consistent with Xinhua's Br value of (8.1+/-5.3)x10^{-5}
