Hard diffractive electroproduction, transverse momentum distribution and QCD vacuum structure
Igor Halperin, Ariel Zhitnitsky
We study the impact of the "intrinsic" hadron transverse momentum on the pre-asymptotic behavior of the diffractive electroproduction of longitudinally polarized -meson. Surpri…
Mapping vesicle shapes into the phase diagram: A comparison of experiment and theory
H. -G. Döbereiner, E. Evans, M. Kraus +2
Phase-contrast microscopy is used to monitor the shapes of micron-scale fluid-phase phospholipid-bilayer vesicles in aqueous solution. At fixed temperature, each vesicle undergoes…
Inclusive B \to sg decay in QCD
I. Halperin, M. Lublinsky
The inclusive nonleptonic transition rate of B meson in gluonic penguin channel is calculated in QCD using the heavy quark mass expansion. We found the branching ratio to be approx…
Deconfinement Transition for Quarks on a Line
C. R. Gattringer, L. D. Paniak, G. W. Semenoff
We examine the statistical mechanics of a 1-dimensional gas of both adjoint and fundamental representation quarks which interact with each other through 1+1-dimensional U(N) gauge…
Large Order Behavior of Quasiclassical Euclidean Gravity in Minisuperspace Models
T. Fugleberg, A. Zhitnitsky
We demonstrate in two minisuperspace models that a perturbation expansion of quasiclassical Euclidean gravity has a factorial dependence on the order of the term at large orders. T…
Coulomb drag in double layer electron systems at even denominator filling factors
S. Sakhi
An interacting double layer system, with uniform positive background, is studied at finite temperature in the presense of a strong magnetic field corresponding to half filling in e…
Muon Spin Relaxation Investigation of the Spin Dynamics of Geometrically Frustrated Antiferromagnets Y2Mo2O7 and Tb2Mo2O7 Static Critical Behavior of the Spin-Freezing
S. R. Dunsiger, R. F. Kiefl, K. H. Chow +11
The spin dynamics of geometrically frustrated pyrochlore antiferromagnets Y2Mo2O7 and Tb2Mo2O7 have been investigated using muon spin relaxation. A dramatic slowing down of the mom…
Exploiting Causal Independence in Bayesian Network Inference
N. L. Zhang, D. Poole
A new method is proposed for exploiting causal independencies in exact Bayesian network inference. A Bayesian network can be viewed as representing a factorization of a joint proba…
Boundary conformal field theory approach to the two-dimensional critical Ising model with a defect line
Masaki Oshikawa, Ian Affleck
We study the critical two-dimensional Ising model with a defect line (altered bond strength along a line) in the continuum limit. By folding the system at the defect line, the prob…
The Initial Mass Function: Now and Then
Harvey B. Richer, Gregory G. Fahlman
We examine whether existing data in clusters, both old and young, and in the field of the Galactic disk and halo is consistent with a universal slope for the initial mass function…
Spectral Function Analysis of Fermi Liquids and of Composite Fermions in a Finite Magnetic Field: Renormalised Gaps
S. Curnoe, P. C. E. Stamp
We consider the self-energy and quasiparticle spectrum, for both electrons interacting with phonons, and composite fermions interacting with gauge fluctuations. In both cases we in…
Boundary Condition Changing Operators in Conformal Field Theory and Condensed Matter Physics
Ian Affleck
Boundary condition changing operators in conformal field theory describe various types of "sudden switching" problems in condensed matter physics such as the X-ray edge singularity…
Dirac Quantization of Two-Dimensional Dilaton Gravity Minimally Coupled to N Massless Scalar Fields
Domingo Louis-Martinez
It is shown that the Callan-Giddings-Harvey-Strominger theory on the cylinder can be consistently quantized (using Dirac's approach) without imposing any constraints on the sign of…
How strange a non-strange heavy baryon?
Ariel R. Zhitnitsky
We give some general arguments in favor of the large magnitude of matrix elements of an operator associated with nonvalence quarks in heavy hadrons. We estimate a strange matrix el…
Discordant Redshifts in Compact Groups
A. Iovino, P. Hickson
This paper addresses the long standing question of discordant redshifts in compact groups. We have used an homogenous catalogue of 173 compact groups selected by an automated proce…
Exact Quantum States for all Two-Dimensional Dilaton Gravity Theories
Domingo Louis-Martinez
It is shown that the recently obtained quantum wave functionals in terms of the CJZ variables for generic 2d dilaton gravity are equivalent to the previously reported exact quantum…
Superconducting transition induced by columnar disorder in strong magnetic field
Igor F. Herbut
The superconducting transition in presence of strong columnar disorder parallel to the magnetic field is considered. A solvable model appropriate for description of the broad cross…
Continuum dual theory of the transition in 3D lattice superconductor
Igor F. Herbut
A recently proposed form of dual theory for the three dimensional superconductor is rederived starting from the lattice electrodynamics and studied by renormalization group. The su…
Characterization of Solidified Gas Thin Film Targets via Alpha Particle Energy Loss
MUH collaboration, M. C. Fujiwara, G. A. Beer +15
A method is reported for measuring the thickness and uniformity of thin films of solidified gas targets. The energy of alpha particles traversing the film is measured and the energ…
Magnetization plateaus in spin chains: ``Haldane gap'' for half-integer spins
Masaki Oshikawa, Masanori Yamanaka, Ian Affleck
We discuss zero-temperature quantum spin chains in a uniform magnetic field, with axial symmetry. For integer or half-integer spin, , the magnetization curve can have plateaus a…
Generalized London free energy for high- vortex lattices
Ian Affleck, Marcel Franz, M. H. Sharifzadeh Amin
We generalize the London free energy to include four-fold anisotropies which could arise from d-wave pairing or other sources in a tetragonal material. We use this simple model to…

G. Grignani, G. Semenoff, P. Sodano +1
We show that the problem of computing the vacuum expectation values of gauge invariant operators in the strong coupling limit of topologically massive gauge theory is equivalent to…
