Search for Long-Lived Neutral Particles Decaying into Lepton Jets in Proton-Proton Collisions at √s = 8 TeV with the ATLAS Detector
Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called "lepton jets"). These particles can also be ...
Measurement of the Higgs Boson Mass from the H → γγ and H → ZZ* → 4ℓ Channels in pp Collisions at Center-Of-Mass Energies of 7 and 8 TeV with the ATLAS Detector
(American Physical Society, 2014-09-09)
An improved measurement of the mass of the Higgs boson is derived from a combined fit to the reconstructed invariant mass spectra of the decay channels H → γγ and H → ZZ∗ → 4ℓ. The analysis uses the pp collision data sample ...
Search for Scalar Diphoton Resonances in the Mass Range 65-600 GeV with the ATLAS Detector in pp Collision Data at √s = 8 TeV
(American Physical Society, 2014-10-20)
A search for scalar particles decaying via narrow resonances into two photons in the mass range 65-600 GeV is performed using 20.3 fb⁻¹ of √s = 8 TeV pp collision data collected with the ATLAS detector at the Large Hadron ...
