We present recent results from the CMS experiment of searches for massive vector-like top and bottom quark partners using data collected in proton-proton collisions at centre-of-mass energy of sqrt(s)=8 TeV. These partners can be found in models addressing the hierarchy problem to stabilize the mass of the Higgs boson. The searches span a range of final states, from multi-lepton to entirely...

The naturalness argument for theories beyond the Standard Model supports
the presence of fermionic top/bottom quark partners, usually referred to
as vector-like quarks (VLQs), to cancel mass divergence for the Higgs boson.
Searches for vector-like quarks have been performed in various final states
with leptons, jets and missing transverse momentum at the ATLAS experiment.

The phenomenology of typical charge 2/3 top partners is determined by their decays T -> th, T -> tZ, T -> bW. Recent CMS and ATLAS searches have bounded the mass of such a top partner to be greater than ~700 GeV. We consider a Little Higgs model in which the quadratically divergent top loops are cancelled by a single top partner which is odd under a parity that forbids the couplings...

Non-minimal universal extra dimensions (nmUED) involve the choice of boundary localized kinetic terms (BLKT) for the 5 dimensional gauge bosons and fermions. We find that with suitable choice of these parameters needed to explain the current Higgs data, the BLK terms removes the approximate degeneracy of the KK mass spectrum, and the pair productions of the level-1 quarks and gluons give rise...

I will discuss discovery potential of new physics at hadron colliders using the recently proposed on-shell constrained $M_2$ variables. Particular focus is upon new physics signatures in the top quark sector, for which regular pair-produced top quarks are dominant background. The relevant signal processes are featured by an *asymmetric* event topology, whereas top quark pairs are *symmetric*....

Many extensions to the Standard Model predicts new particles decaying into
two massive bosons (WW, WZ, ZZ and HH). Searches for such diboson resonances
have been performed in final states with different numbers of leptons and jets
including fat-jets with jet substructure. Searches for new physics in other
final states are also carried out. This talk summarizes ATLAS searches for...

New results on searches for heavy resonances decaying to pairs of Standard Model bosons (WW, WZ, ZZ, WH, ZH, HH) based on the full dataset (L = 19.7fb-1) of proton-proton collisions at sqrt(s) = 8 TeV collected by the CMS detector at the LHC are presented. Several New Physics scenarios including extra dimensions, composite Higgs models, and the recently proposed heavy vector triplet (HVT)...

Searches for resonant pair production of Higgs bosons at the LHC using the CMS apparatus through various decay channels are presented. The analyses use Run I pp collision data recorded at sqrt(s) = 8 TeV. Upper limits on the production cross section of massive resonances between 250 GeV and 1.1 TeV are reported, and constraints on theories with extended Higgs sectors and Randall Sundrum...
