Tau custodian searches at the LHC Águila Giménez, Francisco Del Carmona Bermúdez, Adrián Santiago Pérez, José Large hadron collider Tau physics Strong electroweak symmetry breaking Custodial symmetry The tau lepton can be more composite than naively expected in models of strong electroweak symmetry breaking with tri-bimaximal lepton mixing. New leptonic resonances required by custodial symmetry, the tau custodians, can then be the first signal of this lepton flavor realization. Tau custodians can be very light, decaying almost exclusively into taus. The LHC reach for these new leptons is up to masses of 240, 480 and 720 GeV for sqrt{s}=14 TeV and an integrated luminosity of 30, 300 and 3000 fb^{-1}, respectively. Our analysis can be extended to any pair produced particles decaying mostly into taus and Standard Model bosons. 2014-03-06T13:28:37Z 2014-03-06T13:28:37Z 2011 info:eu-repo/semantics/article Águila, F.; Carmona, A.; Santiago, J.
