CP Violation -- An Essential Mystery in Nature's Grand Design

I. Bigi

CP violation has so far been observed in one system only, namely in the decays of neutral kaons, and it can still be described by a single real quantity corresponding to a superwea…

Collective motion of self-propelled particles: kinetic phase transition in one dimension

Andras Czirok, Albert-Laszlo Barabasi, Tamas Vicsek

We demonstrate that a system of self-propelled particles (SPP) exhibits spontaneous symmetry breaking and self-organization in one dimension, in contrast with previous analytical p…

An invariant of smooth 4-manifolds

Laurence R. Taylor

We define a diffeomorphism invariant of smooth 4-manifolds which we can estimate for many smoothings of R^4 and other smooth 4-manifolds. Using this invariant we can show that unco…

Mean Field Theory of Polynuclear Surface Growth

E. Ben-Naim, A. R. Bishop, I. Daruka +1

We study statistical properties of a continuum model of polynuclear surface growth on an infinite substrate. We develop a self-consistent mean-field theory which is solved to deduc…

Red Clump Stars as a Tracer of Microlensing Optical Depth

David P. Bennett

Zaritsky and Lin have recently suggested that the color magnitude diagram of the Large Magellanic Cloud (LMC) contains evidence of foreground red clump stars. They interpret this a…

Relativistic Hydrodynamics in Close Binary Systems: Analysis of Neutron-Star Collapse

G. J. Mathews, P. Marronetti, J. R. Wilson

We discuss the underlying relativistic physics which causes neutron stars to compress and collapse in close binary systems as has recently been observed in numerical (3+1) dimensio…

Vertex Effects at Future Colliders

E. Gabrielli, V. A. Ilyin, B. Mele

We show that the Higgs production in collisions, through the one-loop reaction at large transverse momentum, can provide a precise determination of the vertex…
