abstract
Applying asymptotic expansions at threshold, we compute the two-loop QCD correction to the short-distance coefficient that governs the leptonic decay $\psi\to l^+ l^-$ of a S-wave quarkonium state and discuss its impact on the relation between the quarkonium non-relativistic wave function at the origin and the quarkonium decay constant in full QCD.

Semi-analytical two-loop QCD corrections to $e^+e^-\to J/\psi+\chi_{cJ}$ at B factories
Semi-analytical NNLO QCD corrections to e+e- -> J/psi + chi_cJ are computed via asymptotic expansions, yielding large corrections that reduce scale dependence for some channels and a discrepancy with Belle data on the...

Renormalisation and matching of massless scalar correlation functions in Soft de Sitter Effective Theory
SdSET is shown to renormalise and match like a flat-space EFT: tree-level trispectrum and six-point matching plus a one-loop power-spectrum match determine the SdSET couplings and initial-condition functions.

Impact of relativistic corrections to high-pT prompt-psi(2S) production at hadron colliders
Relativistic O(v^2) corrections to color-singlet fragmentation functions, especially for gluons, bring leading-power NRQCD predictions for prompt psi(2S) at high pT into agreement with LHC data without color-octet mat...

Rare $W \to B_c + \gamma$ decay up to the NNLO and NLL accuracy in QCD
The rare decay W to Bc plus photon gets NNLO QCD corrections that reduce the width by 31 percent, giving a branching fraction of 1.522 times 10 to the minus 10 after NLL resummation.
