The search for the Higgs boson dimuon decay in standard model (SM) and its minimal supersymmetric extension (MSSM) based on the proton-proton collision data collected with the CMS detector at LHC is presented. To enhance the sensitivity of the search, events are categorised according to different production mechanisms and the dimuon invariant mass. Upper limits on the production cross section...

The search for the production of the Higgs Boson with a pair of top-anti-top quarks is both very important and very challenging. The final results from run-1 are presented, with about 20 fb^(-1) of data at 8 TeV, as well as first run-2 results with 3.2 fb^(-1) of data at 13 TeV.

The current status of the searches for invisible and quasi invisible decays, decays to J/Psi+Gamma, and lepton flavour violation (emu, etau, mutau) decays of the boson will be reviewed, based on pp collision data collected at centre-of-mass energies of 7 and 8 TeV by the CMS...

Many supersymmetry models feature gauginos and also sleptons with masses less than a few hundred GeV. These can give rise to direct pair production rates at the LHC that can be observed in the data sample recorded by the ATLAS detector. The talk summarises the status of searches for gaugino and slepton pair production in final states with leptons.

A search for electroweak production of supersymmetric particles is performed with two tau leptons in the final state. These results are based on 18.1 to 19.6 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}$ = 8\TeV collected with the CMS detector at the CERN Large Hadron Collider. The observed events are found to be consistent with the standard model prediction. Upper limits are set on the...

Electroweak Physics and Beyond the Standard Model
The proton-proton collisions at sqrt{s} = 13 TeV at the LHC have increased the ATLAS sensitivity to production of strongly produced supersymmetric particles. If R-parity is not conserved, these particles may decay to jets and leptons, and lightest supersymmetric particles may decay into many leptons with or without missing transverse momentum. Several supersymmetric models also predict...

Electroweak Physics and Beyond the Standard Model
A search is performed on the 8 TeV LHC data for additional scalars and pseudoscalar with masses below the newly discovered higgs boson h(125). These searches are motivated within several BSM theories, most significantly extensions of the non mininal extensions of the MSSM like the NMSSM, where additional scalar and pseudoscalar states are expected. The mass range from 350 MeV to 110 GeV is...

Resonant production of two bosons (gammagamma, VV, VH and HH) is a
clear hint for physics beyond the Standard Model, potentially related to
the nature of electroweak symmetry breaking mechanism in the SM. Searches
for diboson resonances have been performed in gammagamma and in
final states with different
numbers of leptons and jets including cases where the two jets are merged
into one...

At the LHC dark matter particles can be produced in association
with other particles which mainly come from initial state
radiation. Searches for such processes are presented using events with
jets, photons or massive gauge bosons recoiling against large missing
transverse momentum in ATLAS at 13 TeV. These “mono-X” signatures provide
powerful probes to dark matter production at the LHC,...

The high-mass resonant production of bottom-quark pairs is also a good benchmark process for high-pT b-quark tagging.

We discuss a scenario in which the enhancement in the diphoton
final state at $M_{\gamma \gamma}$ = 750 GeV, recently observed
by the ATLAS and CMS collaborations, is a technipion. We consider two
different detailed minimal scenarios. In a first one
(vector-like technicolor model)
we assume that the vector-boson fusion is a dominant production mechanism.
In a second one (one family...

Monte Carlo event generators are currently very important tools for the comparison between theory and experiment at particle colliders. Today, these tools typically reach NLO precision in QCD for the fixed-order matrix element. In order to improve this precision, Monte Carlo event generators must compute to NLO in EW as well as to NNLO in QCD. The inclusion of a full NLO EW calculation is...
