$D \to (K π)_{27}$ at the SU(3)-flavour-symmetric point I: Methodology and strong phase determination

Matthew Black, Felix Erben, Maxwell T. Hansen +5

We present part one of an SU(3)-flavour-symmetric lattice QCD calculation of the amplitude for a $D$ -meson decaying to a $K π$ final state in the 27-dimensional irreducible represen…

Resolving the $T_{cc}^{+}$ with $π$ Exchange from Lattice QCD

Nelson Pitanga Lachini, Raúl A. Briceño

We revisit the lattice QCD description of the doubly charmed tetraquark $T_{cc}^{+}$ using a finite-volume scattering formalism that incorporates one-pion exchange nonperturbatively,…

$K π$ scattering as a step towards $B \to K^{*} ℓ^{+} ℓ^{-}$ from Lattice QCD

Felix Erben, Matthew Black, Peter Boyle +7

Rare $b \to s ℓ^{+} ℓ^{-}$ decays provide some of the most sensitive tests of the Standard Model and require precise and systematically improvable hadronic input from lattice QCD. F…

Coupled-channel scattering of $D D, D D^{}$ and $D^{} D^{*}$ in isospin- $1$ from lattice QCD

Nelson Pitanga Lachini, Christopher E. Thomas, David J. Wilson

The first coupled-channel determination of two-body $D$ and $D^{*}$ scattering amplitudes in isospin- $1$ from lattice quantum chromodynamics is presented. Using three lattice volumes…

Exploring distillation at the SU(3) flavour symmetric point

Felix Erben, Maxwell T. Hansen, Fabian Joswig +2

In these proceedings we present an exact distillation setup with stabilised Wilson fermions at the SU(3) flavour symmetric point utilising the flexibility of the Grid and Hadrons s…

Towards $K π$ scattering with domain-wall fermions at the physical point using distillation

Nelson Pitanga Lachini, Peter Boyle, Felix Erben +2

Resonances play an important role in Standard Model phenomenology. In particular, hadronic resonances feature in $B$ and $D$ decays, which can be central for New Physics searches.…

$K π$ scattering at physical pion mass using distillation

Nelson Pitanga Lachini, Peter Boyle, Felix Erben +2

Scattering at physical pion mass is still an exploratory field in lattice QCD. This generally involves the extraction of excited states through multi-particle correlators on system…
