WebAchieving the full potential of the LHC will challenge our understanding and description of events with multiple jets. A detailed understanding and description of the multi-jet predictions arising from the Standard Model (SM) is necessary in order to fully disentangle this contribution from that which might arise from much sought-after extensions of the … Web7 de out. de 2015 · We analyse the impact of the higher-order corrections to mono-jet signals in various benchmark scenarios with spin-1 (vector and axial-vector) mediators, calculate DM production cross sections (both total and differential) at NLO accuracy with up to two jets, and also merge the corresponding samples via the FxFx procedure [ 20 ]. Web26 de nov. de 2013 · The full electroweak and QCD induced contributions and their interferences are calculated at leading order. We find that, for inclusive cuts, the interference effects can be large if the jets are produced with large transverse momentum where, however, the production rate is suppressed. foamy water from faucet
