Measurement of the Top Quark Mass in ppbar Collisions at sqrt(s) = 1.96 TeV using the Decay Length Technique
A. Abulencia et al.
We report the first measurement of the top quark mass using the decay length technique in ppbar collisions at a center-of-mass energy of 1.96 TeV. This technique uses the measured…
Cross Section Measurements of High- Dilepton Final-State Processes Using a Global Fitting Method
M. Kruse
We present a new method for studying high- dilepton events (, , ) and simultaneously extracting the production cross sections o…
Eternal inflation, bubble collisions, and the persistence of memory
Jaume Garriga, Alan H. Guth, Alexander Vilenkin
A ``bubble universe'' nucleating in an eternally inflating false vacuum will experience, in the course of its expansion, collisions with an infinite number of other bubbles. In an…
Commensurability classes of 2-bridge knot complements
Alan W. Reid, Genevieve S. Walsh
We show that a hyperbolic 2-bridge knot complement is the unique knot complement in its commensurability class. We also discuss constructions of commensurable hyperbolic knot compl…
Freak observers and the measure of the multiverse
Alexander Vilenkin
I suggest that the factor in the pocket-based measure of the multiverse, , should be interpreted as accounting for equilibrium de Sitter vacuum fluctuations, whi…
Anthropic predictions for vacuum energy and neutrino masses in the light of WMAP-3
Levon Pogosian, Alexander Vilenkin
Anthropic probability distributions for the cosmological constant and for the sum of neutrino masses are updated using the WMAP-3 data release. The new distribution for Lambda is i…
