SUMMARY:$SU(3)_F$ Analysis for Beauty Baryon Decays
DESCRIPTION:Featuring Avital Dery\, Cornell University\n\nPart of the HET S
	eminar Series.\n\nThe measurement of rare b-baryon decays at LHCb can teach
	 us about isospin breaking and $SU(3)_F$ breaking. We perform a general $SU
	(3)_F$ analysis of $b \to c\bar{c}s(d)$ decays of members of the beauty  ba
	ryon antitriplet to a member of the light baryon octet and a singlet. Under
	 several reasonable assumptions we find ${\cal A}(\Xi^0_b \to \Lambda S)/{\
	cal A}(\Xi^0_b \to \Xi^0 S) \approx 1/\sqrt{6} |V^*_{cb}V_{cd}/(V^*_{cb}V_{
	cs})|$ and ${\cal A}(\Lambda_b \to \Sigma_0 S)/{\cal A}(\Lambda_b \to \Lamb
	da S) \sim 0.02$. These two relations have been recently probed by LHCb for
	 the case of $S = J/\Psi$. The former agrees with the measurement\, while f
	or the latter our prediction lies close to the upper bound set by LHCb. We 
	discuss the implications of these measurements in terms of our understandin
	g of isospin breaking as well as of dynamic mixing of the $SU(3)_F$ baryon 
	states.
