Elastic s-wave scattering phase shifts and |Vub| from lattice calculations of form factors for exclusive semileptonic decays
J. M. Flynn, J. Nieves
Omnes dispersion relations make a connection between form factors for exclusive semileptonic decays and phase shifts in the corresponding elastic scattering channels. We describe t…
Improved B -> pi l nu_l form factors from the lattice
UKQCD Collaboration, K. C. Bowler, L. Del Debbio +6
We present the results of a lattice computation of the form factors for B^0 ->pi^- l^+nu_l decays near zero-recoil. These results will allow a determination of the CKM matrix eleme…
First Lattice Study of Semileptonic Decays of Lambda_b and Xi_b Baryons
UKQCD Collaboration, K. C. Bowler, R. D. Kenway +7
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 funct…
Heavy Baryon Specroscopy from the Lattice
UKQCD Collaboration
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…
An ``Improved" Lattice Study of Semi-leptonic Decays of D-Mesons
UKQCD Collaboration
We present results of a lattice computation of the matrix elements of the vector and axial-vector currents which are relevant for the semi-leptonic decays and $D…
The Isgur-Wise Function from the Lattice
the UKQCD Collaboration
We calculate the Isgur-Wise function by measuring the elastic scattering amplitude of a meson in the quenched approximation on a lattice at , using an $O(…
