Question: Consider the decays of the J/ into with their measured branching ratios and Determine the isospin of the J/. J/y pa pTt (1.69 0.15)

Consider the decays of the J/ψ into ρπ with their measured branching ratios

 J/y → pa pTt (1.69 ± 0.15) x 10-2 all  


and

 J/w → p°z° 0_0 (0.56 + 0.07) × 10-2 all


Determine the isospin of the J/ψ.

J/y pa pTt (1.69 0.15) x 10-2 all J/w pz 0_0 (0.56 + 0.07) 10-2 all
