$D \to (K π)_{27}$ 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…

$T_{cc}$ pole trajectory

Protick Mohanta, Srijit Paul, Subhasish Basak

We investigate the spectrum of doubly charmed tetraquark $T_{cc}$ with quantum number $I (J^{P}) = 0 (1^{+})$ using MILC's $N_{f} = 2 + 1 + 1$ HISQ gauge ensembles at two lattice spacings. We…

$B \to ρ ℓ ν ˉ$ resonance form factors from $B \to π π ℓ ν ˉ$ in lattice QCD

Luka Leskovec, Stefan Meinel, Marcus Petschlies +3

The decay $B \to ρ ℓ ν ˉ$ is an attractive process for determining the magnitude of the smallest CKM matrix element, $∣ V_{u b} ∣$ , and can provide new insights into the origin of…

Lattice outlook on $B \to ρ ℓ ν ˉ$ and $B \to K^{⋆} ℓℓ$

Luka Leskovec, Stefan Meinel, Marcus Petschlies +4

Lattice Quantum Chromodynamics (QCD) has significantly contributed to our understanding of the CKM matrix through precise determinations of hadronic matrix elements. With advanceme…

Elastic Nucleon-Pion scattering amplitudes in the $Δ$ channel at physical pion mass from Lattice QCD

Constantia Alexandrou, Simone Bacchio, Giannis Koutsou +4

We present an investigation of pion-nucleon elastic scattering in the $I (J^{P}) = \frac{3}{2} (\frac{3}{2}^{+})$ channel using lattice QCD with degenerate up and down, strange and c…

A lattice QCD study of the $B \to π π ℓ ν ˉ$ transition

Luka Leskovec, Stefan Meinel, Marcus Petschlies +4

$V_{u b}$ is the smallest and least known of all CKM matrix elements; the community currently determines its magnitude primarily through the exclusive process $B \to π ℓ ν ˉ$ . Here…
