Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Samir Garzon, Richard A. Webb, Mark Covington, Shehzaad Kaka, Thomas M. Crawford | Summary: In large magnetoresistance devices spin torque-induced changes in resistance can produce GHz current and voltage oscillations which can affect magnetization reversal. In addition, capacitive shunting in large resistance devices can further reduce […]
Kavli Affiliate: Karen L. Byrum | First 5 Authors: Robert G. Wagner, Karen L. Byrum, Mayly Sanchez, Alexandre V. Vaniachine, Oswald Siegmund | Summary: We advocate support of research aimed at developing alternatives to the photomultiplier tube for photon detection in large astroparticle experiments such as gamma-ray and neutrino astronomy, and direct dark matter detectors. […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Joshua A. Frieman, , , , | Summary: The discovery ten years ago that the expansion of the Universe is accelerating put in place the present cosmological model, in which the Universe is composed of 4% baryons, 20% dark matter, and 76% dark energy. Yet the […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Yang Bai, Marcela Carena, Eduardo Ponton, , | Summary: We propose a scenario in which the Planck scale is dynamically linked to the electroweak scale induced by top condensation. The standard model field content, without the Higgs, is promoted to a 5D warped background. There is also […]
Kavli Affiliate: Scott P. Wakely | First 5 Authors: H. S. Ahn, P. S. Allison, M. G. Bagliesi, J. J. Beatty, G. Bigongiari | Summary: We present new measurements of heavy cosmic-ray nuclei at high energies per- formed during the first flight of the balloon-borne cosmic-ray experiment CREAM (Cosmic-Ray Energetics And Mass). This instrument uses […]
Kavli Affiliate: Luca Grandi | First 5 Authors: R. Acciarri, M. Antonello, B. Baibussinov, M. Baldo-Ceolin, P. Benetti | Summary: A dedicated test of the effects of Oxygen contamination in liquid Argon has been performed at the INFN-Gran Sasso Laboratory (LNGS, Italy) within the WArP R&D program. Two detectors have been used: the WArP 2.3 […]
Kavli Affiliate: Paolo Privitera | First 5 Authors: M. Ave, , , , | Summary: The fluorescence detection of ultra high energy cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules over a wide range of atmospheric parameters, corresponding to altitudes typical of the cosmic ray shower development in the […]
Kavli Affiliate: Edward Kolb | First 5 Authors: Edward W. Kolb, , , , | Summary: In these two lectures I will discuss some outstanding problems in the standard model of cosmology, concentrating on the physics that might be related to the title of this school, “Searching for the totally unexpected in the LHC era.” […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Savdeep Sethi, , , , | Summary: We show that a class of torsional compactifications of the heterotic string are dual to conventional Kahler heterotic string compactifications. This observation follows from the recently proposed analogue of the c-map for the heterotic string. | Search Query: arXiv Query: […]
Kavli Affiliate: Paolo Privitera | First 5 Authors: AIRFLY Collaboration, , , , | Summary: The fluorescence detection of ultra high energy (> 10^18 eV) cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules, which are excited by the cosmic ray shower particles along their path in the atmosphere. We […]
