A novel approach for computing glueball masses and matrix elements in Yang-Mills theories on the lattice
Michele Della Morte, Leonardo Giusti
We make use of the global symmetries of the Yang-Mills theory on the lattice to design a new computational strategy for extracting glueball masses and matrix elements which achieve…
B meson spectrum and decay constant from Nf=2 simulations
Benoit Blossier, John Bulava, Michele Della Morte +8
We report on the status of an ALPHA Collaboration project to extract quantities for B physics phenomenology from Nf=2 lattice simulations. The framework is Heavy Quark Effective Th…
Recent results from heavy flavour physics on the lattice
Michele Della Morte
We discuss some recent lattice results on a few selected hadronic quantities relevant for heavy flavour phenomenology and present some recent theoretical developments. We put the e…
The leading hadronic vacuum polarisation on the lattice
Michele Della Morte, Benjamin Jager, Andreas Juttner +1
After discussing the relevance of a first principles theory-prediction of the hadronic vacuum polarisation for Standard Model tests, the theoretical challenges for its computation…
Quark disconnected diagrams in chiral perturbation theory
Michele Della Morte, Andreas Juttner
We show how quark-disconnected and quark-connected contributions to hadronic n-point functions can be written as independent correlators for which one can derive expressions in par…
HQET at order 1/m: III. Decay constants in the quenched approximation
Benoît Blossier, Michele Della Morte, Nicolas Garron +4
We report on the computation of the meson decay constant in Heavy Quark Effective Theory on the lattice. The next to leading order corrections in the HQET expansion are inclu…
HQET at order : II. Spectroscopy in the quenched approximation
Benoît Blossier, Michele Della Morte, Nicolas Garron +4
Using Heavy Quark Effective Theory with non-perturbatively determined parameters in a quenched lattice calculation, we evaluate the splittings between the ground state and the firs…
Towards Precision B-physics from Non-Perturbative Heavy Quark Effective Theory
Michele Della Morte, Jochen Heitger
We convey an idea of the significant recent progress, which opens up good perspectives for high-precision ab-initio computations in heavy flavour physics based on lattice QCD. Rath…
HQET at order 1/m: I. Non-perturbative parameters in the quenched approximation
Benoît Blossier, Michele Della Morte, Nicolas Garron +1
We determine non-perturbatively the parameters of the lattice HQET Lagrangian and those of the time component of the heavy-light axial-vector current in the quenched approximation.…
