Zusammenfassung: | The LHC potential for discovering doubly charged vector bileptons is investigated considering the measurable process pp→μ+μ+μ−μ−X. The study is performed assuming different bilepton and leptoquark masses. The process cross section is calculated at leading order using the Calchep package. Combining the calculation with the latest ATLAS experiment results at a center-of-mass energy of 7 TeV, bounds on bilepton masses based on LHC data are derived for the first time. The results exclude bilepton masses in the range of 250 GeV to 500 GeV at 95% C.L., depending on the leptoquark mass. Moreover, minimal LHC integrated luminosities needed for discovering and for setting limits on bilepton masses are obtained for 13 TeV center-of-mass energy. Simulated events are passed through a fast parametric detector simulation using the Delphes package. |
