Lattice QCD calculations have reached per-mille-level precision for certain experimentally measurable quantities. Often, the limiting systematic uncertainty of such computations comes from determination of the lattice scale, converting the lattice results to physical units. A number of lattice collaborations carried out determinations of theoretical scales (e.g., a popular choice is the gradient flow scale) that are in slight tension. Lattice scale determination with fully accounted systematic uncertainties is not a purely theoretical question as it influences, for instance, the computation of the hadronic contribution to the anomalous magnetic moment of the muon and the determination of the CKM matrix elements. Thus, the precision of the lattice scale plays a direct role in confirming the Standard Model or differentiating new physics beyond the Standard Model

The workshop aims to examine current state and recent advances in nuclear astrophysics and identify crucial reactions that require assessment of information relevant to the field using stable and Radioactive Ion Beam (RIB) facilities. The workshop will bring together experimentalists and theoreticians studying nuclear reactions, along with physicists engaged in stellar and stellar-explosion modeling as well as in astronomical observations and cosmochemistry. The primary objective is to identify stellar scenarios that necessitate accurate nuclear reaction data, which significantly impact stellar evolution, and determine the most effective methods to obtain such data. The workshop will establish a collaborative framework and encourage joint activities among the participating scientists to facilitate the comparison of reaction studies using different and complementary techniques.
