The Vacuum Structure of Light-Front -Theory
T. Heinzl, C. Stern, E. Werner +1
We discuss the vacuum structure of -theory in 1+1 dimensions quantised on the light-front . To this end, one has to solve a non-linear, operator-valued constraint equa…
Hadronic Rare Decays via Exchange or Annihilation Diagrams
Zhi-zhong Xing
The two-body mesonic decays induced only via a single -exchange or annihilation quark diagram, such as and $\bar{B}^0_d\rightarrow D^{(…
Possible Effects of Mixing in Weak Decays
Zhi-zhong Xing
mixing at a detectable level requires the presence of new physics and may lead to some observable effects in weak decays of mesons. We show that violation…
On the quantum probability flux through surfaces
M. Daumer, D. Duerr, S. Goldstein +1
We remark that the often ignored quantum probability current is fundamental for a genuine understanding of scattering phenomena and, in particular, for the statistics of the time a…
A Time-independent Way to Probe D^0-\bar D^0 Mixing at Tau-charm Factories
Zhi-zhong Xing
mixing leads to the mass and width differences in the mass eigenstates of and mesons (measured by parameters and respectively)…
D^0 \to K^{\pm}π^{\mp} and CP Violation at a τ-charm Factory
Zhi-zhong Xing
We calculate the time-dependent and time-integrated decay rates of at the and resonances. The possi…
The Light Higgsino-Gaugino Window
Jonathan L. Feng, Nir Polonsky, Scott Thomas
Supersymmetric models are typically taken to have parameter and all soft supersymmetry breaking parameters at or near the weak scale. We point out that a small window of allowe…
On the Ubiquity of K3 Fibrations in String Duality
Paul S. Aspinwall, Jan Louis
We consider the general case of N=2 dual pairs of type IIA/heterotic string theories in four dimensions. We show that if the type IIA string in this pair can be viewed as having be…
q-deformed Phase Space and its Lattice Structure
M. Fichtmueller, A. Lorek, J. Wess
A q-deformed two-dimensional phase space is studied as a model for a noncommutative phase space. A lattice structure arises that can be interpreted as a spontaneous breaking of a c…
Physical phase space of lattice Yang-Mills theory and the moduli space of flat connections on a Riemann surface
S. A. Frolov
It is shown that the physical phase space of $\g$-deformed Hamiltonian lattice Yang-Mills theory, which was recently proposed in refs.[1,2], coincides as a Poisson manifold with th…
On the Flux-Across-Surfaces Theorem
M. Daumer, D. Dürr, S. Goldstein +1
The quantum probability flux of a particle integrated over time and a distant surface gives the probability for the particle crossing that surface at some time. We prove the free F…
Higher-Dimensional Algebra I: Braided Monoidal 2-Categories
John C. Baez, Martin Neuchl
We begin with a brief sketch of what is known and conjectured concerning braided monoidal 2-categories and their applications to 4d topological quantum field theories and 2-tangles…
Nucleon Spin and the Mixing of Axial Vector Mesons
Michael Birkel, Harald Fritzsch
It is shown that the QCD anomaly may lead to an abnormal mixing behavior of the axial vector mesons similar to the pseudoscalar mesons. These mixing effects, involving a gluonic ax…
EPR-Bell Nonlocality, Lorentz Invariance, and Bohmian Quantum Theory
K. Berndl, D. Duerr, S. Goldstein +1
We discuss the problem of finding a Lorentz invariant extension of Bohmian mechanics. Due to the nonlocality of the theory there is (for systems of more than one particle) no obvio…
The performance of Lagrangian perturbation schemes at high resolution
Thomas Buchert, Georgios Karakatsanis, Robert Klaffl +1
We present high--spatial resolution studies of the density field as predicted by Lagrangian perturbation approximations up to the third order. The first--order approximation is equ…
On Testing Unitarity of the Quark Mixing Matrix
Zhi-zhong Xing
Unitarity triangles and characteristic measurables of the Cabibbo-Kobayashi-Maskawa (CKM) matrix are discussed. Beyond the CKM scheme we make a rephasing-in…
On the Relation Between the Holomorphic Prepotential and the Quantum Moduli in SUSY Gauge Theories
J. Sonnenschein, S. Theisen, S. Yankielowicz
We give a simple proof of the relation $Λ\p_artialΛ\F= {i\over2π}b_1\langle\Trϕ^2\rangle$, which is valid for supersymmetric QCD with massless quarks. We consider g…
B Meson Form Factors and Exclusive Decays
A. Khodjamirian, R. Rückl
We present results for the and form factors derived from QCD sum rules on the light-cone. Our predictions are compared with experiment and used t…
On Quantum Groups in the Hubbard Model with Phonons
Bianca L. Cerchiai, Peter Schupp
The correct Hamiltonian for an extended Hubbard model with quantum group symmetry as introduced by A. Montorsi and M. Rasetti is derived for a D-dimensional lattice. It is shown th…
Large enhancement of deuteron polarization with frequency modulated microwaves
The SMC Collaboration
We report a large enhancement of 1.7 in deuteron polarization up to values of 0.6 due to frequency modulation of the polarizing microwaves in a two liters polarized target using th…
Averaging inhomogeneous Newtonian cosmologies
Thomas Buchert, Juergen Ehlers
Idealizing matter as a pressureless fluid and representing its motion by a peculiar--velocity field superimposed on a homogeneous and isotropic Hubble expansion, we apply (Lagrangi…
The mass of the eta' in self-dual QCD
Marcus Hutter
The QCD gauge field is modeled as an ensemble of statistically independent selfdual and antiselfdual regions. This model is motivated from instanton physics. The scale anomaly then…
Lepton Mass Hierarchy and Neutrino Oscillations
H. Fritzsch, Z. Z Xing
Starting from the symmetry of lepton flavor democracy, we propose and discuss a simple pattern for the mass generation and flavor mixing of the charged leptons and neutrinos. The t…
Self-trapping of the dilaton
Rainer Dick
The dilaton in three dimensions does not roll. Witten's conjecture that duality between theories in three and four dimensions solves the cosmological constant problem thus may also…
