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

Nelson Pitanga Lachini, RaÃºl A. BriceÃ±o

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 I ¨ $ 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…
