Towards a solution for the weak radiative hyperon decays puzzle

The weak radiative hyperon decays problem is a long standing puzzle of about 50 years. It has its origin in the results of experiment [1] which showed a large asymmetry in the decay  Sigma+  >  p gamma, violating, thus, Hara’s theorem [2] which, at the hadron level, states that the parity-violating amplitude of the above decay  vanishes in exact SU(3)-flavor symmetry.

[1] L. K. Gershwin et al., Phys. Rev. 188, 2077 (1969).

[2]  Y. Hara, Phys. Rev. Lett. 12, 378 (1964).

 

I show in this paper that this is another proof of quark compositeness. Please, take a look at the paper by clicking right here.
