DESCRIPTION:Theoretical calculations of nuclear reactions provide critical
inputs for modeling of important astrophysical\, cosmological and experim
ental processes such as stellar nuclear burning\, big-bang nucleosynthesis
and neutrino detection. Precision calculations with well-justified uncert
ainty estimates are needed both for cross sections probed by ongoing and p
lanned experiments\, and for those that are probed imprecisely or not at a
ll by available experimental techniques. Nuclear theory is in a better pos
ition than ever to provide such calculations owing to (i) continuing devel
opments in effective field theories of quantum chromodynamics that enable
us to calculate low-energy reactions involving light nuclei and halo/clust
er nuclei in a systematically improvable framework\, and (ii) recent progr
ess in techniques for rigorous treatment of uncertainties in such calculat
ions.\n\nThis Virtual Workshop will bring together experts working on (i)
formal developments in effective field theories of the strong interactions
and electroweak currents\, (ii) applications of such approaches to specif
ic nuclear reactions\, (iii) parameter estimation\, model selection\, opti
mization and statistical uncertainty analysis techniques applicable for nu
clear theory\, (iv) astrophysical models that need precise nuclear rates\,
(v) precision cross section measurements. The Workshop aims to help nucle
ar theorists prioritize important processes where precise calculations are
feasible\, forge collaborations to study them\, discuss both current prac
tice for uncertainty quantification in these reactions and how to improve
it\, identify the course of action that needs to be taken to push uncertai
nty quantification in calculations of nuclear reactions beyond the current
state of the art\, and learn what approaches will get buy-in from experim
entalists and astrophysicists.\n\nhttps://indico.mitp.uni-mainz.de/event/2
