Decays of b quark
Tomasz Skwarnicki
Importance of studies of quark decays and experimental status of various measurements are discussed.
Morse Theory and the Topology of Configuration Space
W. D. McGlinn, L. O'Raifeartaigh, S. Sen +1
The first and second homology groups are computed for configuration spaces of framed three-dimensional point particles with annihilation included, when up to two particles and an a…
Singular Vertices and the Triangulation Space of the D-sphere
S. Catterall, G. Thorleifsson, J. Kogut +1
By a sequence of numerical experiments we demonstrate that generic triangulations of the sphere for contain one {\it singular} simplex. The mean number of element…
Edge States and Entanglement Entropy
A. P. Balachandran, L. Chandar, Arshad Momen
It is known that gauge fields defined on manifolds with spatial boundaries support states localized at the boundaries. In this paper, we demonstrate how coarse-graining over these…
Cosmological-Parameter Determination with Microwave Background Maps
Gerard Jungman, Marc Kamionkowski, Arthur Kosowsky +1
The angular power spectrum of the cosmic microwave background (CMB) contains information on virtually all cosmological parameters of interest, including the geometry of the Univers…
A Specimen of Theory Construction from Quantum Gravity
Rafael D. Sorkin
I describe the history of my attempts to arrive at a discrete substratum underlying the spacetime manifold, culminating in the hypothesis that the basic structure has the form of a…
