mesons: semileptonic and nonleptonic decays
C. Albertus, E. Hernandez, J. Nieves +1
In this contribution we compute some nonleptonic and semileptonic decay widths of mesons, working in the context of constituent quark models \cite{Albertus:2014gba, Albertus:…
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…
|Vub| from exclusive semileptonic B to pi decays revisited
Jonathan M Flynn, Juan Nieves
We update the extraction of |Vub| from exclusive semileptonic B to pi decays, combining experimental partial branching fraction information with theoretical form factor calculation…
Study of the semileptonic decays B->pi, D->pi and D->K
C. Albertus, J. M. Flynn, E. Hernandez +2
The semileptonic decay B->pi is studied starting from a simple quark model that takes into account the effect of the B* resonance. A novel, multiply subtracted, Omnes dispersion re…
Semileptonic Decays from an Omnès Improved Nonrelativistic Constituent Quark Model
C. Albertus, J. M. Flynn, E. Hernández +2
The semileptonic decay is studied starting from a simple quark model which includes the influence of the pole. To extend the predictions of a nonrelativistic…
Form Factors for Semileptonic B -> pi and D -> pi Decays from the Omnes Representation
J. M. Flynn, J. Nieves
We use the Omnes representation to obtain the q-squared dependence of the form factors f+ and f0 for semileptonic H -> pi decays from the elastic pi H -> pi H scattering amplitudes…
