Can supersymmetry breaking lead to electroweak symmetry breaking via formation of scalar bound states?
John M. Cornwall, Alexander Kusenko, Lauren Pearce +1
The recent discovery of the putative 125-GeV Higgs boson has motivated a number of attempts to reconcile its relatively large mass with the predictions of the minimal supersymmetri…
Moduli dark matter and the search for its decay line using Suzaku X-ray telescope
Alexander Kusenko, Michael Loewenstein, Tsutomu T. Yanagida
Light scalar fields called moduli arise from a variety of different models involving supersymmetry and/or string theory; thus their existence is a generic prediction of leading the…
Cosmic connections: from cosmic rays to gamma rays, to cosmic backgrounds and magnetic fields
Alexander Kusenko
Combined data from gamma-ray telescopes and cosmic-ray detectors have produced some new surprising insights regarding intergalactic and galactic magnetic fields, as well as extraga…
TeV gamma rays from blazars beyond z=1?
Felix Aharonian, Warren Essey, Alexander Kusenko +1
At TeV energies, the gamma-ray horizon of the universe is limited to redshifts z<<1, and, therefore, any observation of TeV radiation from a source located beyond z=1 would call fo…
Light Sterile Neutrinos: A White Paper
K. N. Abazajian, M. A. Acero, S. K. Agarwalla +184
This white paper addresses the hypothesis of light sterile neutrinos based on recent anomalies observed in neutrino experiments and the latest astrophysical data.
Primordial seeds of supermassive black holes
Masahiro Kawasaki, Alexander Kusenko, Tsutomu T. Yanagida
Supermassive black holes exist in the centers of galaxies, including Milky Way, but there is no compelling theory of their formation. Furthermore, observations of quasars imply tha…
Dark Matter Search Using XMM-Newton Observations of Willman 1
Michael Loewenstein, Alexander Kusenko
We report the results of a search for an emission line from radiatively decaying dark matter in the ultra-faint dwarf spheroidal galaxy Willman 1 based on analysis of spectra extra…
Time structure of gamma-ray signals generated in line-of-sight interactions of cosmic rays from distant blazars
Anton Prosekin, Warren Essey, Alexander Kusenko +1
Blazars are expected to produce both gamma rays and cosmic rays. Therefore, observed high-energy gamma rays from distant blazars may contain a significant contribution from seconda…
