Dark Radiation and Localization of Gravity on the Brane
Rui Neves, Cenalo Vaz
We discuss the dynamics of a spherically symmetric dark radiation vaccum in the Randall-Sundrum brane world scenario. Under certain natural assumptions we show that the Einstein eq…
Spacetime-varying couplings and Lorentz violation
Alan Kostelecky, Ralf Lehnert, Malcolm Perry
Spacetime-varying coupling constants can be associated with violations of local Lorentz invariance and CPT symmetry. An analytical supergravity cosmology with time-varying fine-str…
On the proximate order of growth of generating functions of Polya frequency sequences
Maria Teresa Alzugaray
We study the possible growth of g.f.'s analytic in the unit disk and describe the proximate orders of growth of these functions. Some classical function theory results conce…
Domains of holomorphy of generating functions of Polya frequency sequences of finite order
Maria Teresa Alzugaray
A domain $G\subset \bar\mathbb C$ is the domain of holomorphy of the generating function of a Pólya frequency sequence of order if and only if it satisfies the following condit…
Elliptic Flow from Color Glass Condensate
Alex Krasnitz, Yasushi Nara, Raju Venugopalan
We show that an observable fraction of the measured elliptic flow may originate in classical gluon fields at the initial stage of a peripheral high-energy nuclear collision. This m…
Gluon production in the Color Glass Condensate model of collisions of ultrarelativistic finite nuclei
Alex Krasnitz, Yasushi Nara, Raju Venugopalan
We extend previous work on high energy nuclear collisions in the Color Glass Condensate model to study collisions of finite ultrarelativistic nuclei. The changes implemented includ…
