In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8 level and beyond. [...]

Four-lepton production in gluon fusion at NLO matched to parton showers
/ Alioli, Simone (Milan Bicocca U.) ; 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. The calculation consistently incorporates the continuum background, the Higgs-mediated $gg\to H^* \to VV$ process, and their interference. [...]

Monte Carlo event generators for high energy particle physics event simulation
/ Buckley, Andy (ed.) (Glasgow U.) ; Krauss, Frank (ed.) (Durham U.) ; Plätzer, Simon (ed.) (Vienna U.) ; Seymour, Michael (ed.) (Manchester U.) ; Alioli, Simone (Milan Bicocca U.) ; Andersen, Jeppe (Durham U.) ; Bellm, Johannes (Lund U.) ; Butterworth, Jon (University Coll. London) ; Dasgupta, Mrinal (Manchester U.) ; Duhr, Claude (CERN ; University Coll. London) et al.
Monte Carlo event generators (MCEGs) are the indispensable workhorses of particle physics, bridging the gap between theoretical ideas and first-principles calculations on the one hand, and the complex detector signatures and data of the experimental community on the other hand. [...]

Catching a New Force by the Tail
/ Alioli, Simone (CERN ; Milan Bicocca U.) ; Farina, Marco (Rutgers U., Piscataway) ; Pappadopulo, Duccio (New York U. ; New York U., CCPP) ; Ruderman, Joshua T. (New York U. ; New York U., CCPP)
The Large Hadron Collider (LHC) is sensitive to new heavy gauge bosons that produce narrow peaks in the dilepton invariant mass spectrum up to about $m_{Z'}\sim 5$ TeV. $Z'$s that are too heavy to produce directly can reveal their presence through interference with Standard Model dilepton production.
