Form factor relations for heavy-to-light meson transitions: tests of the Quark Model predictions
Joao M. Soares
In the case of heavy-to-light weak meson transitions, a Quark Model derivation leads to very general relations between the form factors that parametrize the hadronic matrix element…
Form factor relations for pseudoscalar to vector meson transitions
Joao M. Soares
In semi-leptonic and other weak decays of mesons, the hadronic matrix elements of the operators in the weak Hamiltonian are parametrized by standard sets of independent, Lorentz in…
QCD corrections to B -> J/psi + anything
Joao M. Soares, Tibor Torma
We calculate the branching ratio for B -> J/psi + anything, within the color-singlet approximation for J/psi production, but including perturbative QCD corrections beyond the leadi…
Form factor relations for heavy-to-heavy and heavy-to-light meson transitions
Joao M. Soares
Relations between the form factors that parametrize the hadronic matrix elements, in spectator decays of heavy mesons, have been derived by Stech within the constituent quark model…
Combining exclusive semi-leptonic and hadronic B decays to measure |V_ub|
Joao M. Soares
The Cabibbo-Kobayashi-Maskawa matrix element |V_ub| can be extracted from the rate for the semi-leptonic decay B -> pi + l + antineutrino_l, with little theoretical uncertainty, pr…
Systematics of soft final state interactions in decay
John F. Donoghue, Eugene Golowich, Alexey A. Petrov +1
By using very general and well established features of soft strong interactions we show, contrary to conventional expectations, that (i) soft final state interactions (FSI) do not…
``Non-factorizable'' terms in hadronic B-meson weak decays
Joao M. Soares
The branching ratios for the hadronic B-meson weak decays B -> J/psi K and B -> D pi are used to extract the size of the ``non-factorizable'' terms in the decay amplitudes. It is p…
Constraints on Extended Technicolor Models from B -> mu+ mu- X
Benjamin Grinstein, Yosef Nir, Joao M. Soares
A recent study by Randall and Sundrum shows that models of Extended Technicolor (ETC) have interesting implications on rare B decays. We extend their study to the decay B -> mu+ mu…
