A Non-Abelian Variation on the Savvidy Vacuum of the Yang-Mills Gauge Theory

Suzhou Huang, A. R. Levi

As a prelude to a truly non-perturbative evaluation of the effective potential in terms of lattice QCD, the one loop effective potential for a non-Abelian gauge configuration is ca…

Monte Carlo Simulations of the SU(2) Vacuum Structure

A. R. Levi

Lattice Monte Carlo simulations are performed for the SU(2) Yang Mills gauge theory in the presence of an Abelian background with external sources to obtain information on the effe…

An Extended Technicolor Model

Thomas Appelquist, John Terning

An extended technicolor model is constructed. Quark and lepton masses, spontaneous CP violation, and precision electroweak measurements are discussed. Dynamical symmetry breaking i…

Fluctuation Induced First Order Phase Transitions

Yue Shen

We study a symmetric scalar field model in four and three dimensions. First, using our data in four dimensions in the weak coupling region, we demonstrate explici…

Surfactant-Mediated Surface Growth: Nonequilibrium Theory

Albert-Laszlo Barabasi

A number of recent experiments have showed that surfactants can modify the growth mode of an epitaxial film, suppressing islanding and promoting layer-by-layer growth. Here a set o…

Exact N=2 Landau-Ginzburg Flows

Paul Fendley, Ken Intriligator

We find exactly solvable N=2-supersymmetric flows whose infrared fixed points are the N=2 minimal models. The exact S-matrices and the Casimir energy (a c-function) are determined…

Central charges without finite-size effects

Paul Fendley, Ken Intriligator

We show how to obtain the ultraviolet central charge from the exact S-matrix for a wide variety of models with a symmetry. This is done by coupling the current to…

A Lattice Calculation of the Isgur-Wise Function

C. Bernard, Y. Shen, A. Soni

We calculate the Isgur-Wise function () by measuring the heavy-heavy meson transition matrix element on the lattice in the quenched approximation. The standard Wilson action i…

The Implications of Naturalness in Effective Field Theory on the Masses of Resonances

Michael J. Dugan, Mitchell Golden

Many years ago Weinberg formulated a definition of ``naturalness'' for effective theories: if an effective theory is to make sense, coefficients must not change too much when the c…

Walking Technicolor And The Vertex

R. S. Chivukula, E. Gates, E. H. Simmons +1

A slowly running technicolor coupling will affect the size of non-oblique corrections to the vertex from extended technicolor dynamics. We show that while ``walking tech…

Phenomenology of a Non-Standard Higgs

R. Sekhar Chivukula, Vassilis Koulovassilopoulos

The one-Higgs-doublet standard model is necessarily incomplete because of the triviality of the scalar symmetry-breaking sector. If the Higgs mass is approximately 600 GeV or highe…

Self-consistently Improved Finite Temperature Effective Potential for Gauge Theories

G. Amelino-Camelia

The finite temperature effective potential of the Abelian Higgs Model is studied using the self-consistent composite operator method, which sums up the contributions of daisy and s…

Massless Flows II: the exact S-matrix approach

P. Fendley, H. Saleur, Al. B. Zamolodchikov

We study the spectrum, the massless S-matrices and the ground-state energy of the flows between successive minimal models of conformal field theory, and within the sine-Gordon mode…

Static Properties of Quark Solitons

Gonen Gomelski, Marek Karliner, Stephen B. Selipsky

It has been conjectured that at distances smaller than the confinement scale but large enough to allow for nonperturbative effects, QCD is described by an effective $SU(N_c {\times…
