چکیده
First Lattice Study of Semileptonic Decays of Λ b and Ξ b Baryons. Abstract We present the results of the first lattice study of semileptonic decays of baryons containing a b-quark. Predictions for the decay distributions are given and the Isgur-Wise functions for heavy baryons are computed, for values of the velocity transfer up to about ω = 1.2. The computations are performed on a 24 3 ×48 lattice at β = 6.2 using the Sheikholeslami-Wohlert action in the quenched approximation.

Study of Charm Baryons with the BaBar Experiment
We report on several studies of charm baryon production and decays by the BABAR collaboration. We confirm previous observations of the Ξ ′ 0/+ c , Ξ c (2980) + and Ξ c (3077) + baryons, measure branching ratios for Cabibbo-suppressed Λ + c decays and use baryon decays to study the properties of the light-quark baryons, Ω − and Ξ(1690) 0 .

Weak radiative decays of beauty baryons into strange baryons, induced by the elec-troweak penguin, are estimated by using a quark model approach. Relations between formfactors in the semileptonic and in the weak radiative decays are derived within the heavy quark effective theory. The partial decay widths are found to be of the order of 10 −15 MeV for Λ b → Λγ and Ξ b → Ξγ and of the oder of 10...

The results of an exploratory lattice study of heavy baryon spectroscopy are presented. We have computed the full spectrum of the eight baryons containing a single heavy quark, on a 24 3 × 48 lattice at β = 6.2, using an O(a)-improved fermion action. We discuss the lattice baryon operators and give a method for isolating the contributions of the spin doublets (Σ, Σ *), (Ξ ′ , Ξ *) and (Ω, Ω *) ...
متن کاملMasses and semileptonic decays of doubly heavy baryons in a nonrelativistic quark model
We evaluate masses and semileptonic decay widths for the ground state of doubly heavy Ξ and Ω baryons in the framework of a nonrelativistic quark model. We solve the three-body problem by means of a variational ansatz made possible by heavy-quark spin symmetry constraints. Our masses are comparable to the ones obtained in relativistic calculations and we get one of the best agreements with latt...
متن کاملWeak decays Ξ Q → Λ Q π
The weak decays Ξ b → Λ b π and Ξ c → Λ c π, in which the heavy quark is not destroyed, are discussed. The branching fractions for these decays, corresponding to an absolute rate of order 0.01 ps −1 , should be at a one percent level for the b hyperons and at a (few) per mill level for Ξ c , possibly making feasible their experimental study in future. It is shown, through an application of the ...
