Precision Higgs Coupling Measurements In H→ww*→lνlν Final State With The Atlas Detector At The Lhc
The Standard Model (SM) is a gauge theory that describes the fundamental particles of matter and the forces between these particles. It has been tested to a very high precision in the past several decades, except for ... -
Probing The 5f Electrons: A Relativistic DFT Study Of Americium Surfaces
(Physics, 2008-09-17)Surface chemistry and physics have been and continues to be very active fields of research because of the obvious scientific and technological implications and consequent importance of such research. One of the many ... -
Propagation And Generation Of Waves In Solar Atmosphere
(Physics, 2010-03-03)The fact that the temperature increases with height in the solar atmosphere has been known for many years. To maintain this temperature increase, sources of heating must be present in the atmosphere. One of the most ... -
PROSPECTS FOR OBSERVING DYNAMICALLY FORMED BINARY BLACK HOLES IN THE LOCAL UNIVERSE WITH GRAVITATIONAL WAVES
(2018-06-07)The dynamical evolution of globular clusters is expected to produce stellar-mass binary black holes with higher total mass than found in the field population of binary black holes. Such systems are identified as gravitational ... -
Quantum Modeling Of Dark Matter In Galactic Halos
(Physics, 2013-03-20)Eighty years after its initial discovery, the nature of dark matter remains a mystery. Contrary to observational evidence, simulations of dark matter halos predict cuspy density profiles and an abundant population of dwarf ... -
The Role Of The Y-component Of The Interplanetary Magnetic Field In Transpolar Saturation And Ring Current Response As Found In Data And Simulation
(Physics, 2010-07-19)Energy is transferred into the magnetosphere of Earth through merging of magnetic fields (Dungey cycle and lobe cell convection) and through momentum transfer across the magnetopause (viscous interactions). These processes ... -
