Constraining flavorful SMEFT operators with missing energy plus jetGudrun Hiller and •Daniel Wendler — TU Dortmund University, Department of Physics, Otto-Hahn-Str.4, D-44221 Dortmund, Germany

We consider the Drell-Yan process with final state neutrinos, where the experimental signature is given by "missing energy + jet", as a probe for new physics. The process pp → ν ν+ jet is analyzed, to constrain flavorful semileptonic four-fermion operators based on present LHC data (Lint= 139   fb−1). Projections are derived for the High Luminosity Large Hadron Collider (HL-LHC). New physics scales probed are ΛNP ∼ 3.5   TeV, 3.0 TeV, 2.6 TeV and 1.6  TeV for uc, ds, db and sb, respectively for four-fermion operators. The limits are complementary and competitive or better to those from Drell-Yan involving taus, and with low energy observables, such as from rare decays of kaons, charm and beauty hadrons.
