“…The remaining five Higgs scalar mass eigenstates consist of two CP-even neutral scalars h 0 and H 0 , one CP-odd neutral scalar A 0 and a charge +1 scalar H + as well as its charge conjugate H − with charge −1. 9 The gauge-eigenstate fields can be expressed in terms of the mass eigenstate fields as…”

We study an extension of the MSSM by an anomalous abelian vector multiplet and a Stückelberg multiplet. The anomalies are cancelled by the Green-Schwarz mechanism and the addition of Chern-Simons terms. The advantage of this choice over the standard one is that it allows for arbitrary values of the quantum numbers of the extra U (1). As a first step towards the study of hadron annihilations producing four leptons in the final state (a clean signal which might be studied at LHC) we then compute the decays Z ′ → Z 0 γ and Z ′ → Z 0 Z 0 . We find that the largest values of the decay rate is ∼ 10 −4 GeV, while the expected number of events per year at LHC is at most of the order of 10.

“…One of the most attractive scenario for physics beyond the SM is the existence of additional massive neutral gauge bosons [1]- [9]. They could be one of the first discoveries at LHC if their mass is in the range of a few TeV.…”

“…Concerning the study presented here, earlier works focusing on extra singlet scalars or E 6inspired U(1) augmented gauge groups in non-suspersimmetric [21,22] and suspersimmetric [23,24] extensions of the SM, respectively, have already been considered.…”

We present the complete set of Renormalisation Group Equations (RGEs) at one loop for the non-exotic minimal U (1) extension of the Standard Model (SM). It includes all models that are anomaly-free with the SM fermion content augmented by one Right-Handed (RH) neutrino per generation. We then pursue the numerical study of the pure B − L model, deriving the triviality and vacuum stability bounds on an enlarged scalar sector comprising one additional Higgs singlet field with respect to the SM.
