Standard Model tests with smeared experiment and theory / Jüttner, Andreas (CERN ; Southampton U.)
For Standard Model processes in which on-shell intermediate hadronic states contribute - including inclusive semileptonic decays and long-distance effects in rare exclusive decays such as $D\to π\ell\ell$ and $B\to K^{(\ast)}\ell\ell$ - spectral-reconstruction techniques provide a promising route to model-independent lattice QCD predictions for use in phenomenological predictions.

Factorization Beyond Coherence / Becher, Thomas (U. Bern (main)) ; Hager, Patrick (CERN) ; Neubert, Matthias (U. Mainz, PRISMA ; Cornell U., LEPP) ; Schwienbacher, Dominik (U. Bern (main))
We derive a novel factorization theorem for $N$-jettiness at hadron colliders, which incorporates coherence-violating effects induced by Glauber gluons and several new momentum modes. [...]

Renormalisation and matching of massless scalar correlation functions in Soft de Sitter Effective Theory / Beneke, Martin (Munich, Tech. U.) ; Hager, Patrick (CERN) ; Sanfilippo, Andrea F. (Granada U.)
For light and massless scalar fields, cosmological correlation functions suffer from infrared divergences and secular logarithms. [...]

On Thrust Resummation Ambiguities in $e^+e^-$ Annihilation into Hadrons / Buonocore, Luca (CERN) ; Nason, Paolo (INFN, Milan Bicocca) ; Rottoli, Luca (Milan Bicocca U. (main) ; INFN, Milan Bicocca) ; Torrielli, Paolo (INFN, Turin ; U. Turin (main))
In $e^+e^-$ shape-variable studies, and in particular for the case of thrust, fixed-order QCD predictions are typically supplemented with the resummation of contributions enhanced near the two-jet limit. [...]
