Absence of Species Doubling in Finite-Element Quantum Electrodynamics
Kimball A. Milton
In this letter it will be demonstrated explicitly that the finite-element formulation of quantum electrodynamics is free from fermion doubling. We do this by (1) examining the latt…
A Nonperturbative, Schwinger-Dyson-Equation Analysis of Quark Masses and Mixings in a Model with QCD and Higgs Interactions
Lesley L. Smith, Pankaj Jain, Douglas W. McKay
The Landau gauge Schwinger-Dyson Equation for the quark self-energy is solved in the quenched ladder approximation for several cases of one- and two-quark-generations. The exchange…
On the constrained KP hierarchy II
L. A. Dickey
A constrained KP hierarchy is discussed that was recently suggested by Aratyn et al. and by Bonora et al. This hierarchy is a restriction of the KP to a submanifold of operators wh…
On the constrained KP hierarchy
L. A. Dickey
An explanation for the so-called constrained hierarhies is presented by linking them with the symmetries of the KP hierarchy. While the existence of ordinary symmetries (belonging…
Measurement of the B -> D^* l nu Branching Fractions and |Vcb|
The CLEO Collaboration
We study the exclusive semileptonic B meson decays B- -> D*0 l- nu and B0 -> D*+ l- nu using data collected with the CLEO II detector at CESR. We present measurements of the branch…
Semileptonic Branching Fraction of Charged and Neutral B Mesons
The CLEO collaboration
An examination of leptons in events tagged by reconstructed decays yields semileptonic branching fractions of for charged and $b_0=(10.9…
