Leading-Color Two-Loop QCD Corrections for Three-Jet Production at Hadron Colliders / Abreu, S. ; Cordero, F. Febres ; Ita, H. ; Page, B. ; Sotnikov, V.
We present the complete set of leading-color two-loop contributions required to obtain next-to-next-to-leading-order (NNLO) QCD corrections to three-jet production at hadron colliders. [...]

Adding Flavor to the Narain Ensemble / Datta, Shouvik ; Duary, Sarthak ; Kraus, Per ; Maity, Pronobesh ; Maloney, Alexander
We revisit the proposal that the ensemble average over free boson CFTs in two dimensions - parameterized by Narain's moduli space - is dual to an exotic theory of gravity in three dimensions dubbed $U(1)$ gravity. [...]

Nonlinear gravitational-wave memory from cusps and kinks on cosmic strings / Jenkins, Alexander C. ; Sakellariadou, Mairi
The nonlinear memory effect is a fascinating prediction of general relativity (GR), in which oscillatory gravitational-wave (GW) signals are generically accompanied by a monotonically-increasing strain which persists in the detector long after the signal has passed. [...]

Four-lepton production in gluon fusion at NLO matched to parton showers / Alioli, Simone (University of Milan - Bicocca) ; Ferrario Ravasio, Silvia (Oxford U., Theor. Phys.) ; Lindert, Jonas M. (Sussex U., Astron. Ctr.) ; Röntsch, Raoul (CERN)
We present a calculation of the next-to-leading order (NLO) QCD corrections to gluon-induced electroweak gauge boson pair production, $gg \to ZZ$ and $gg \to W^+W^-$, matched to the PYTHIA8 parton shower in the POWHEG approach. [...]
