A bstractThe interference effects between an extra neutral spin-1 Z′-boson and the Standard Model background in the Drell-Yan channel at the LHC are studied in detail. The final state with two oppositely charged leptons is considered. The interference contribution to the new physics signal, currently not fully taken into account by experimental collaborations in Z′-searches and in the interpretation of the results, can be substantial. It may affect limits or discovery prospects of Z′ at the LHC… 
Drell-Yan production of multi Z′-bosons at the LHC within Non-Universal ED and 4D Composite Higgs Models
A bstractThe Drell-Yan di-lepton production at hadron colliders is by far the preferred channel to search for new heavy spin-1 particles. Traditionally, such searches have exploited the Narrow Width
Interference Effects in tt̄ Production at the LHC as a Window on New Physics
Many extensions of the Standard Model (SM) contain (pseudo)scalar bosons with masses in the TeV range. At hadron colliders, such particles would predominantly be produced in gluon fusion and would
Forward-backward asymmetry as a discovery tool for Z′ bosons at the LHC
A bstractThe Forward-Backward Asymmetry (AFB) in Z′ physics is commonly only perceived as the observable which possibly allows one to interpret a Z′ signal appearing in the Drell-Yan channel by
Interference effects in dilepton resonance searches for Z′ bosons and dark matter mediators
Abstract New Z′ gauge bosons arise in many extensions of the Standard Model and predict resonances in the dilepton invariant mass spectrum. Searches for such resonances therefore provide important
Cross-fertilising extra gauge boson searches at the LHC
Abstract For the purpose of cross-fertilising currently separate experimental approaches, we connect results of LHC analyses attempting to access the properties of additional W′ and Z′ bosons from
Interference effects in tt¯$$ t\overline{t} $$ production at the LHC as a window on new physics
A bstractMany extensions of the Standard Model (SM) contain (pseudo)scalar bosons with masses in the TeV range. At hadron colliders, such particles would predominantly be produced in gluon fusion and
Exclusion and discovery via Drell-Yan in the 4DCHM
Searches for Z' bosons are most sensitive in the dilepton channels at hadron colliders. Whilst finite width and interference effects do affect the modifications the presence of BSM physics makes to
Effects of Z−Z′ mixing in double W-bosons production at the large hadron collider
The potential of the Large Hadron Collider (LHC) for searches for effects associated with Z−Z′ mixing in the hadroproduction of W±-boson pairs is studied. The results of our numerical analysis are
Electroweak tt¯ hadroproduction in the presence of heavy Z′ and W′ bosons at NLO QCD in POWHEG
We extend and improve upon our previous calculation of electroweak topquark pair hadroproduction in extensions of the Standard Model with extra heavy neutral and charged spin-1 resonances. In
Diagnosis of a New Neutral Gauge Boson at the LHC and ILC for Snowmass 2013
A U(1)' or Z' is generic in many scenarios of physics beyond the Standard Model, such as string theory compactifications, GUTs, extra-dimensions, compositeness, dynamical electroweak symmetry

Apart from its mass and width, the most important property of a new charged gauge boson, W{prime}, is the helicity of its couplings to the SM fermions. Such particles are expected to exist in many
