In this paper, we study the extent to which CP parity of a Higgs boson, and more generally its anomalous couplings gauge bosons, can be measured at LHC future electron-positron collider. We consider several processes, including boson production in gluon weak fusion association with an electroweak boson. decays $ZZ, WW, \gamma \gamma$, $Z \gamma$. Matrix element approach three decay topologies is developed applied analysis. A complete Monte Carlo simulation above processes proton $e^+e^-$...
We present an extension of the JHUGen and MELA framework, which includes event generator library for matrix element analysis. It enables simulation, optimal discrimination, reweighting techniques, analysis a bosonic resonance triple quartic gauge boson interactions with most general anomalous couplings. The new features, become especially relevant at current stage LHC data taking, are simulation gluon fusion vector in off-shell region, associated $ZH$ production NLO QCD including $gg$...
We constrain the Higgs boson (Yukawa) coupling to quarks in first two generations $H\ensuremath{\rightarrow}ZZ$ final states. Deviation of these couplings from Standard Model values leads changes width and cross sections relevant processes. In resonance region, an increased light Yukawa width, which turn a decreased section. off-shell result enhancement signal through $q\overline{q}$ annihilation. With assumption scaling one at time, this study is conceptually simple yields results with same...
