A bstract The differential branching fraction of the rare decay Λ 0 b→ Λμ+ μ− is measured as
a function of q 2, the square of the dimuon invariant mass. The analysis is performed using …

We report the first observation of the baryonic flavor-changing neutral current decay Λ b 0→

Using (2+ 1)-flavor lattice QCD, we compute the 10 form factors describing the Λ b→ Λ
matrix elements of the b→ s vector, axial vector, and tensor currents. The calculation is …

We study decay properties of the P-wave charmed baryons using the method of light-cone
QCD sum rules, including the S-wave decays of the flavor 3¯ FP-wave charmed baryons into …

We present a systematic discussion of Λ b→ Λ transition form factors in the framework of soft-
collinear effective theory (SCET). The universal soft form factor, which enters the symmetry …

The differential branching fraction of the rare decay Λ0b→ Λµ+ µ− is measured as a function

A bstract We compute radiative corrections to Λ b→ Λ from factors, at next-to-leading
logarithmic accuracy, from QCD light-cone sum rules with Λ b-baryon distribution …

Using the covariant constituent quark model previously developed by us we calculate the
differential rate and the forward-backward asymmetries on the lepton and hadron side for …

A bstract We study the differential decay rate for the rare Λ b→ Λ (→ Nπ) ℓ+ ℓ− transition,
including a determination of the complete angular distribution, assuming unpolarized Λ b …

A bstract Rare b→ sℓ+ ℓ− flavour-changing-neutral-current processes provide important
tests of the Standard Model of particle physics. Angular observables in exclusive b→ sℓ+ ℓ …
