“…The bosonic sector of the Uð1Þ 0 model shows up through the Z 0 gauge boson and the singlet Higgs boson S. The cleanest and the most direct signal of a Z 0 gauge boson, if accessible at the LHC, will be a new resonance, centered at M '' ¼ M Z 0 , in the dilepton spectrum (' ¼ e or unless otherwise stated) [8,9] …”

“…The collider searches at LEP and Tevatron plus various indirect observations require Z À Z 0 mixing angle ZÀZ 0 to be at most a few 10 À3 with an unavoidable model dependence coming from the Z 0 couplings [7][8][9][10]26,27]. This bound requires either M Z 2 to be large enough (well in the TeV range) or Á 2 to be sufficiently suppressed by the vacuum configuration, that is,…”

Search for gauge extensions of the MSSM at the LHC

The extensions of the minimal supersymmetric model (MSSM), driving mainly from the need to solve the problem, involve novel matter species and gauge groups. These extended MSSM models can be searched for at the LHC via the effects of the gauge and Higgs bosons or their fermionic partners. Traditionally, the focus has been on the study of the extra forces induced by the new gauge and Higgs bosons present in such models. An alternative way of studying such effects is through the superpartners of matter species and the gauge forces. We thus consider a Uð1Þ 0 gauge extension of the MSSM, and perform an extensive study of the signatures of the model through the production and decays of the scalar quarks and gluino, which are expected to be produced copiously at the LHC. After a detailed study of the distinctive features of such models with regard to the signatures at the LHC, we carry out a detailed Monte Carlo analysis of the signals from the process pp ! n leptons þ m jets þ E 6 T , and compare the resulting distributions with those predicted by the MSSM. Our results show that the searches for the extra gauge interactions in the supersymmetric framework can proceed not only through the forces mediated by the gauge and Higgs bosons but also through the superpartner forces mediated by the gauge and Higgs fermions. Analysis of the events induced by the squark/gluino decays presented here is complementary to the direct Z 0 searches at the LHC.

The total cross section and the forward-backward asymmetry for the process e + e ! + (n ) are measured in the energy range 20-136 GeV by reconstructing the e ective centre-of-mass energy after initial state radiation. The analysis is based on the data recorded with the ALEPH detector at LEP between 1990 and 1995, corresponding to a total integrated luminosity of 143.5 pb 1 . Two di erent approaches are used: in the rst one an exclusive selection of events with hard initial state radiation in the energy range 20-88 GeV is directly compared with the Standard Model predictions showing good agreement. In the second one, all events are used to obtain a precise measurement of the energy dependence of 0 and A 0 FB from a model independent t, enabling constraints to be placed on models with extra Z bosons.

An analysis of the data collected in 1997 and 1998 with the DELPHI detector at e + e − collision energies close to 183 and 189 GeV was performed in order to extract the hadronic and leptonic fermion-pair cross-sections, as well as the leptonic forward-backward asymmetries and angular distributions. The data are used to put limit on contact interactions between fermions, the exchange of R-parity violating SUSY sneutrinos, Z ′ bosons and the existence of gravity in extra dimensions.
