abstract
In this brief review, I summarize the current theoretical knowledge of heavy quarkonium inclusive decays, with emphasis on recent progress made in the framework of QCD effective field theories. In appendix, I list the imaginary parts of the matching coefficients of the dimension 6 and dimension 8 NRQCD four-fermion operators as presently known.

Effective field theories for dark matter pairs in the early universe: Debye mass effects
Debye mass resummation reduces bound-state dark matter depletion by up to a factor of two relative to fixed-order NLO, changing relic abundance predictions by a few percent.
