We revisit the hyperon weak radiative decays in the framework of the non-relativistic constituent quark model. This study confirms the nonlocal feature of the hyperon weak radiative transition operators which are dominated by the pole terms, and an overall self-consistent description of the available experimental data for the Cabibbo-favored hyperon weak radiative decays is achieved. It provides a natural mechanism for evading the Hara theorem, where sizeable parity-violating contributions can come from the intermediate orbital excitations. Cancellations between pole terms also explain significant SU(3) flavor symmetry breaking manifested by the experimental data. We also discuss several interesting selection rules arising from either the electromagnetic or the weak interaction vertices. These features suggest nontrivial relations among different hyperon decays.

Unraveling weak radiative hyperon decays with broken flavor symmetry
A broken-SU(3) fit with eight parameters reproduces the observed hyperon radiative decay data and predicts a sizable negative Xi- -> Sigma- gamma asymmetry that current data do not rule out.
-
The Cabibbo-favored hadronic weak decays of the $\Xi_c$ in the quark model
Using direct meson emission, color suppressed, and pole terms in a quark model, the authors reproduce most measured Xi_c decay branching ratios and predict asymmetry parameters, while failing one measured asymmetry sign.

SU(3) flavor symmetry analysis of hyperon non-leptonic two body decays
An SU(3)-based fit with strange-quark-mass corrections reproduces most hyperon decay data, but leaves a weak 1-sigma deviation in Sigma+ to p pi0 that the authors interpret as a possible sign of new physics.
