Leptonic CP violation in a two parameter model
Samina S. Masood, Salah Nasri, Joseph Schechter
We further study the "complementary" Ansatz, Tr=0, for a prediagonal light Majorana type neutrino mass matrix. Previously, this was studied for the CP conserving case and th…
Plans for the LIGO-TAMA Joint Search for Gravitational Wave Bursts
Patrick J. Sutton, Masaki Ando, Patrick Brady +18
We describe the plans for a joint search for unmodelled gravitational wave bursts being carried out by the LIGO and TAMA collaborations using data collected during February-April 2…
Fixed-Connectivity Membranes
Mark J. Bowick
The statistical mechanics of flexible surfaces with internal elasticity and shape fluctuations is summarized. Phantom and self-avoiding isotropic and anisotropic membranes are disc…
Baryogenesis after Hyperextended Inflation
Antonio De Felice, Mark Trodden
We study a baryogenesis mechanism operating in the context of hyperextended inflation and making use of a coupling between the scalar field and a standard model global current, suc…
Molecular Hydrogen Formation on Ice Under Interstellar Conditions
Hagai B. Perets, Ofer Biham, Giulio Manico +4
The results of experiments on the formation of molecular hydrogen on low density and high density amorphous ice surfaces are analyzed using a rate equation model. The activation en…
Cosmic Acceleration and Modified Gravitational Models
Damien A. Easson
There is now overwhelming observational evidence that our Universe is accelerating in its expansion. I discuss how modified gravitational models can provide an explanation for this…
