140. Search for heavy resonances with the ATLAS detector

Katherine Pachal (University of Oxford (GB))

06/05/2014, 16:30

Searches for new physics in the form of resonances are sensitive over a great range of energies and produce a wide variety of experimental signatures. Within ATLAS, resonance searches are particularly popular in exotic analyses because of their relative model independence. This talk will examine a variety of recent results in \sqrt{s}=8 TeV data which span boson, lepton, and jet-based final...

152. Distinguishing Flavor Non-universal Color-singlet and Color-octet Vector Resonances at the LHC

Pawin Ittisamai (Michigan State University)

Electrically-neutral massive color-singlet and color-octet vector bosons, common predictions of beyond the standard model physics, have the potential to be discovered as a resonance in a dijet channel at the LHC. A color-singlet resonance that has leptophobic couplings needs further investigation to be distinguished from the color-octet one. In previous work, we introduced a method for...

28. Search for massive resonances decaying to charged lepton pairs at CMS

Andreas Guth (Rheinisch-Westfaelische Tech. Hoch. (DE))

06/05/2014, 17:00

At the LHC, the production of resonances decaying into pairs of charged leptons can be probed at unprecedented centre-of-mass energies. Results from searches for dilepton resonances at high invariant mass with muons and electrons based on the full dataset of 20/fb taken by the CMS detector in 2012 in proton-proton collisions at a centre-of-mass energy of 8 TeV are presented. The signatures...

150. Searches for vector-like quarks, tt and tb resonances with the ATLAS detector

Nicolas Gilberto Gutierrez Ortiz (University of Glasgow (GB))

06/05/2014, 17:15

With the discovery of the Higgs boson the experiments are now looking with renewed interest for BSM scenarios that would help resolve the hierarchy problem. We will report on searches for vector-like quarks and new heavy bosons that preferentially mix with and couple to $3^{\mathrm{rd}}$ generation quarks, using the 8 TeV data collected by the ATLAS experiment.

39. Constraints on cosmological parameters from Planck and BICEP2 data

Luis Anchordoqui (U)

06/05/2014, 17:30

I will introduce S-dual inflationary potentials that explain the recent measurement of low-multipole B-mode polarization anisotropies by the BICEP2 experiment as arising from primordial tensor fluctuations.

76. New W-prime signals at the LHC

Natascia Vignaroli (Michigan State University)

06/05/2014, 17:45

We study the $W^{'}$ phenomenology in composite Higgs / warped extra dimensional models focusing on the effect of fermionic resonances at the TeV scale. After deriving the existing bounds from the current LHC-8 analyses, we highlight the most promising signatures for $W^{'}$ discovery at the 14 TeV LHC. In particular, we find very promising the study of $W^{'}$ decay modes into vector-like top...

182. Searches for New Physics in Events with Multiple Leptons with the ATLAS Detector

144. Effective operators for coupling adjoint scalar fields to SM gauge bosons

Russell Colburn (O)

06/05/2014, 18:15

We study novel decay topologies for adjoint scalar fields. Such fields appear in many models, such as Minimal Flavor Violating and R-symmetric versions of supersymmetry. We study effective operators where the adjoint scalars couple to pairs of SM gauge bosons. In particular we focus on gluon-photon and gluon-Z decays of colored adjoint scalars. We present sensitivity studies in new channels...
