Setting the scale for the CLS 2 + 1 flavor ensembles
read the original abstract
We present measurements of a combination of the decay constants of the light pseudoscalar mesons and the gradient flow scale $t_0$, which allow to set the scale of the lattices generated by CLS with $2 + 1$ flavors of non-perturbatively improved Wilson fermions. Mistunings of the quark masses are corrected for by measuring the derivatives of observables with respect to the bare quark masses.

The Lambda 1405 at the $SU(3)$ point in lattice QCD
Lattice QCD at the SU(3) symmetric point extracts energy levels for singlet and octet baryon-meson channels to inform the two-pole structure of Lambda(1405).

Finite-volume analysis of the $H$-dibaryon including left-hand-cut effects
Finite-volume N/D analysis with left-hand cuts applied to lattice data shows a mild but statistically significant effect on H-dibaryon binding energy compared to Lüscher quantization.

Comparing RM123 and non-perturbative QCD+QED approaches to the HVP with C-periodic boundary conditions
Full dynamical QCD+QED simulations yield smaller uncertainties than the RM123 method for the intermediate-window HVP contribution at fixed lattice spacing, volume, and statistics.

$f_K/f_{\pi}$ in iso-symmetric QCD and the CKM matrix unitarity
Lattice QCD result for f_K/f_π in isoQCD gives |V_us|/|V_ud| consistent with CKM unitarity once isospin and QED effects are included.
