Search for heavy lepton partners of neutrinos in proton–proton collisions in the context of the type III seesaw mechanism

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

A search is presented in proton–proton collisions at s=7TeV for fermionic triplet states expected in type III seesaw models. The search is performed using final states with three isolated charged leptons and an imbalance in transverse momentum. The data, collected with the …

Search for physics beyond the standard model in events with a Z boson, jets, and missing transverse energy in pp collisions at s=7 TeV

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

A search is presented for physics beyond the standard model (BSM) in events with a Z boson, jets, and missing transverse energy (E miss T ).This signature is motivated by BSM physics scenarios, including supersymmetry.The study is performed using a sample of …

Search for neutral Higgs bosons decaying to tau pairs in pp collisions at s=7 TeV

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

A search for neutral Higgs bosons decaying to tau pairs at a center-of-mass energy of 7 TeV is performed using a dataset corresponding to an integrated luminosity of 4.6 fb−1 recorded by the CMS experiment at the LHC. The search is sensitive …
