Primordial black holes and inflation from double-well potentials
Alexandros Karam, Niko Koivunen, Eemeli Tomberg +2
We investigate the formation of large peaks in the inflationary curvature power spectrum from double-well potentials. In such scenarios, the initial CMB spectrum is created at larg…
Scale-invariance, dynamically induced Planck scale and inflation in the Palatini formulation
Ioannis D. Gialamas, Alexandros Karam, Thomas D. Pappas +2
We present two scale invariant models of inflation in which the addition of quadratic in curvature terms in the usual Einstein-Hilbert action, in the context of Palatini formulatio…
Observation of top-quark pair production in association with a photon and measurement of the production cross section in pp collisions at TeV using the ATLAS detector
ATLAS Collaboration
A search is performed for top-quark pairs () produced together with a photon () with transverse energy greater than 20 GeV using a sample of candidate event…
Search for the lepton flavor violating decay in pp collisions at = 8 TeV with the ATLAS detector
ATLAS Collaboration
The ATLAS detector at the Large Hadron Collider is used to search for the lepton flavor violating process in pp collisions using 20.3 of data collecte…
Electron and photon energy calibration with the ATLAS detector using LHC Run 1 data
ATLAS Collaboration
This paper presents the electron and photon energy calibration achieved with the ATLAS detector using about 25 fb of LHC proton--proton collision data taken at centre-of-mas…
Search for dark matter in events with a Z boson and missing transverse momentum in pp collisions at =8 TeV with the ATLAS detector
ATLAS Collaboration
A search is presented for production of dark matter particles recoiling against a leptonically decaying Z boson in 20.3 fb of pp collisions at =8 TeV with the ATLA…
