WebNov 10, 2014 · The presence of the dark photon would be indicated by the appearance of an unexpected peak in the total mass of its decay products above smooth backgrounds. Dark photons may be expected to decay in … WebThis PhD thesis includes two main topics, the first one is related to the search for dark photons. Two different searches were performed at a centre-of-mass energy of $\sqrt{s}=13$ TeV using the LHC Run-2 integrated luminosity of 139 fb$^{-1}$ recorded by the ATLAS detector, the first search concerns dark photons from the SM Higgs boson …

WebFeb 17, 2014 · Dark energy with negative pressure and positive energy density is believed to be responsible for the accelerated expansion of the universe. Quite a few theoretical models of dark energy are based on tachyonic fields interacting with itself and normal (bradyonic) matter. Here, we propose an experimental model of tachyonic dark energy …
