Exact Path Integrals by Equivariant Cohomology
Hans Dykstra, Joe Lykken, Eric Raiten
It is a common belief among field theorists that path integrals can be computed exactly only in a limited number of special cases, and that most of these cases are already known. H…
Heavy Quark Physics
Paul B. Mackenzie
Lattice calculations of heavy quark systems provide very good measures of the lattice spacing, a key element in recent determinations of the strong coupling constant using lattice…
Properties of Low-Lying Heavy-Light Mesons
Anthony Duncan, Estia Eichten, Aida X. El-Khadra +3
We present preliminary results for the B meson decay constant and masses of low-lying heavy-light mesons in the static limit. Calculations were performed on the lattice in the quen…
The Charmonium Spectrum on the Lattice: A Status Report
Aida X. El-Khadra
We present our most recent results on the charmonium spectrum using relativistic Wilson fermions. We study the dependence of the spectrum on the charm quark mass and the Wohlert-Sh…
The Charm Quark on the Lattice
Andreas S. Kronfeld
We formulate lattice fermions in a way that encompasses Wilson fermions as well as the static and non-relativistic approximations. In particular, we treat systematically ($m…
A streamlined method for chiral fermions on the lattice
Geoffrey T. Bodwin, Eve V. Kovacs
We discuss the use of renormalization counterterms to restore the chiral gauge symmetry in a lattice theory of Wilson fermions. We show that a large class of counterterms can be im…
Gravitational Radiation from Colliding Vacuum Bubbles: Envelope Approximation to Many-Bubble Collisions
Arthur Kosowsky, Michael S. Turner
We introduce an approximation to calculate the gravitational radiation produced by the collision of true-vacuum bubbles that is simple enough to allow the simulation of a phase tra…
Final-State Interaction of Longitudinal Vector Bosons
J. -L. Basdevant, E. L. Berger, D. Dicus +2
In the standard Higgs model of electroweak symmetry breaking, the Higgs boson is associated with both vector-boson and fermion mass generation. In contrast, we discuss a two-Higgs-…
SO(4) Invariant States in Quantum Cosmology
Fay Dowker
The phenomenon of linearisation instability is identified in models of quantum cosmology that are perturbations of mini-superspace models. In particular, constraints that are secon…
Effect of Neutrino Heating on Primordial Nucleosynthesis
B. Fields, S. Dodelson, M. S. Turner
We have modified the standard code for primordial nucleosynthesis to include the effect of the slight heating of neutrinos by annihilations. There is a small, systematic ch…
Novel Spin and Statistical Properties of Nonabelian Vortices
Lee Brekke, Hans Dykstra, Adam F. Falk +1
We study the statistics of vortices which appear in (2+1)--dimensional spontaneously broken gauge theories, where a compact group G breaks to a finite nonabelian subgroup H. Two si…
How Effective is the Effective Potential?
Scott Dodelson, Ben-Ami Gradwohl
Motivated by bubble nucleation in first order phase transitions, we question the validity of the effective potential for inhomogeneous configurations. In an attempt to get some ins…
Flavor Asymmetry of the Nucleon Sea: Consequences for Dilepton Production
Estia J. Eichten, Ian Hinchliffe, Chris Quigg
Parton distributions derived from a chiral quark model that generates an excess of down quarks and antiquarks in the proton's sea satisfactorily describe the measured yields of muo…
Spontaneously Broken Technicolor and the Dynamics of Virtual Vector Technimesons
Christopher T. Hill, Dallas C. Kennedy, Tetsuya Onogi +1
We propose spontaneously breaking technicolor, thus liberating techniquarks and suppressing large resonance contributions to the electroweak parameter. The dynamics is modeled…
Inflation at the Electroweak Scale
L. Knox, M. S. Turner
We present a simple model for slow-rollover inflation where the vacuum energy that drives inflation is of the order of ; unlike most models, the conversion of vacuum ener…
On the Viability of Lattice Perturbation Theory
G. P. Lepage, P. B. Mackenzie
In this paper we show that the apparent failure of QCD lattice perturbation theory to account for Monte Carlo measurements of perturbative quantities results from choosing the bare…
Anomalous Gauge-Boson Couplings at Hadron Supercolliders
G. Valencia
We discuss anomalous gauge boson couplings at hadron supercolliders. We review the usual description of these couplings, as well as the studies of a strongly interacting electrowea…
Metastable Cosmic Strings in Realistic Models
R. Holman, S. D. H. Hsu, T. Vachaspati +1
We investigate the stability of the electroweak Z-string at high temperatures. Our results show that while finite temperature corrections can improve the stability of the Z-string,…
Critical Behavior in the Electroweak Phase Transition
Marcelo Gleiser, Edward W. Kolb
We examine the behavior of the standard-model electroweak phase transition in the early Universe. We argue that close to the critical temperature it is possible to estimate the {\i…
Continuum Gauge Fields from Lattice Gauge Fields
M. Goeckeler, A. S. Kronfeld, G. Schierholz +1
On the lattice some of the salient features of pure gauge theories and of gauge theories with fermions in complex representations of the gauge group seem to be lost. These features…
The gravitational wave contribution to CMB anisotropies and the amplitude of mass fluctuations from COBE results
F. Lucchin, S. Matarrese, S. Mollerach
A stochastic background of primordial gravitational waves may substantially contribute, via the Sachs--Wolfe effect, to the large--scale Cosmic Microwave Background (CMB) anisotrop…
Breakdown of Dimensional Regularization in the Sudakov Problem
J. C. Collins, F. V. Tkachov
An explicit example is presented (a one-loop triangle graph) where dimensional regularization fails to regulate the infra-red singularities that emerge at intermediate steps of stu…
Natural Inflation: Particle Physics Models, Power Law Spectra for Large Scale Structure, and Constraints from COBE
Fred Adams, J. R. Bond, Katherine Freese +2
A pseudo-Nambu-Goldstone boson, with a potential of the form f \sim M_{Pl}Λ\sim M_{GUT}$. We show how thi…
Cosmic Microwave Background Probes Models of Inflation
R. L. Davis, H. M. Hodges, G. F. Smoot +2
Inflation creates both scalar (density) and tensor (gravity wave) metric perturbations. We find that the tensor mode contribution to the CMB anisotropy on large-angular scales can…
