Search for new phenomena in final states with large jet multiplicities and missing transverse momentum at sqrt(s)=8 TeV proton-proton collisions using the ATLAS experiment

  title={Search for new phenomena in final states with large jet multiplicities and missing transverse momentum at sqrt(s)=8 TeV proton-proton collisions using the ATLAS experiment},
  author={Atlas Collaboration},
A search is presented for new particles decaying to large numbers (7 to greater or equal to 10) of jets, missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3/fb of pp collision data at sqrt(s)=8 TeV collected by the ATLAS experiment at the Large Hadron Collider. The sensitivity of the search is enhanced by considering the number of b-tagged jets and the scalar sum of masses of large-radius jets in an event. No evidence is found for physics beyond the Standard… 

Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at $ \sqrt{s} $ = 8 TeV

A bstractA search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at $ \sqrt{s} $ = 8 TeV using a data sample corresponding

  • Physics
  • 2014
A search for supersymmetry or similar new physics is carried out using a sample with 19.5 fb−1 integrated luminosity of √ s = 8 TeV pp collisions collected by the CMS experiment at the LHC. Our main

Search for supersymmetry at CMS in proton-proton collisions with center-of-mass energy of 13 TeV in the single-lepton final state using the sum of masses of large-radius jets

Author(s): Dishaw, Adam Leo | Advisor(s): Richman, Jeffrey D | Abstract: This dissertation describes a search for supersymmetry in 35.9 fb^{-1} of proton-proton collisions with sqrt(s) = 13 TeV

Inclusive search for supersymmetry using razor variables in pp collisions at ffiffi s p = 13 TeV

An inclusive search for supersymmetry using razor variables is performed in events with four or more jets and no more than one lepton. The results are based on a sample of proton-proton collisions

LHC searches examined via the RPV MSSM

We confront the ATLAS and CMS new physics searches with simplified models from R-parity violating (RPV) supersymmetry that contain naturally light stops and higgsinos. We emphasize the important role

Strong supersymmetry: A search for squarks and gluinos in hadronic channels using the ATLAS detector

Previous experiments have not found evidence for supersymmetric particles, and set limits on the mass of supersymmetric particles. However, with the high collision energies achieved at the Large

Search for dark matter and compressed mass-spectra supersymmetry with the vector boson fusion topology in pp collisions at sqrt(s) = 8 TeV

  • Physics
  • 2015
The first search for dark matter candidate production through pure electroweak vector boson fusion processes is presented. Events with two jets in the vector boson fusion topology and large missing

Search for scalar top quarks decaying into scalar tau leptons with ATLAS at $\sqrt s $= 8 TeV

This thesis presents a search for Supersymmetry carried out in a particular scenario arising from the Gauge Mediated Supersymmetry breaking mechanism that assumes a massless gravitino as lightest

Identifying fake leptons in ATLAS while hunting SUSY in 8 TeV proton-proton collisions

For several theoretically and experimentally motivated reasons, super- symmetry (SUSY) has for some time been identified as an interesting candidate for a theory of fundamental particle physics

The Hunt for Supersymmetry at the Tevatron

Model-independent and model-dependent limits on new particle production are set, and interpretations in supersymmetric models are given, and several limits from the Large Electron Positron (LEP) era have been extended.
