An effective field theory of QCD at high density
Deog Ki Hong
We derive a (Wilsonian) effective field theory of QCD at finite density by integrating out the states in the Dirac sea when the chemical potential . The quark-gluo…
Flavour Universal Dynamical Electroweak Symmetry Breaking
Gustavo Burdman, Nick Evans
The top condensate see-saw mechanism of Dobrescu and Hill allows electroweak symmetry to be broken while deferring the problem of flavour to an electroweak singlet, massive sector.…
Lepton Number Violation in Top-Color Assisted Technicolor
Tonguc Rador
We calculate the rates for lepton number violating processes via the exchange of the Z' boson occuring in top-color assisted technicolor. The current experimental limits on muon el…
Non-Perturbative Couplings and Color Superconductivity
Nick Evans, Stephen Hsu, Myckola Schwetz
Quark matter at sufficiently high density exhibits color superconductivity, due to attractive gluonic interactions. At lower densities of order , it has been proposed th…
Dijet Mass Spectrum Limits on Flavor-Universal Colorons
Iain Bertram, Elizabeth H. Simmons
Using recent D0 data on the dijet mass spectrum, we present a limit on flavor-universal colorons. At 95% CL we find Mc/cot(theta) > 837 GeV. We discuss the implications of this lim…
An Effective Field Theory Approach to Color Superconductivity at High Quark Density
Nick Evans, Stephen D. H. Hsu, Myckola Schwetz
We investigate the Fermi Liquid theory of high density QCD. Using the renormalization group (RG), we determine the behavior of effective fermion interactions near the Fermi surface…
Top Quark Seesaw Theory of Electroweak Symmetry Breaking
R. Sekhar Chivukula, Bogdan A. Dobrescu, Howard Georgi +1
We study electroweak symmetry breaking involving the seesaw mechanism of quark condensation. These models produce a composite Higgs boson involving the left-handed top quark, yet t…
Saturating the Bound on the Scale of Fermion Mass Generation
R. Sekhar Chivukula
Recently, Jaeger and Willenbrock have shown that the Appelquist and Chanowitz bound on the scale of top-quark mass generation can formally be saturated in a particular limit of a t…
Top-Bottom Splitting in Technicolor with Composite Scalars
Bogdan A. Dobrescu, Elizabeth H. Simmons
We present a model of dynamical electroweak symmetry breaking in which the splitting between the top and bottom quark masses arises naturally. The W and Z masses are produced by a…
Compactification for a Three-Brane Universe
Raman Sundrum
A fully realistic and systematic effective field theory model of a 3-brane universe is constructed. It consists of a six-dimensional gravitating spacetime, containing several, appr…
A Heavy Top Quark From Flavor-Universal Colorons
Marko B. Popovic, Elizabeth H. Simmons
Ordinary technicolor and extended technicolor cannot produce the heavy top quark unaided. We demonstrate that a flavor-universal extension of the color interactions combined with a…
Effective Field Theory of Vacuum Tilting
R. Sekhar Chivukula, Howard Georgi
Simple models of topcolor and topcolor-assisted technicolor rely on a relatively strong U(1) gauge interaction to ``tilt'' the vacuum. This tilting is necessary to produce a top-co…
Large-N and Vacuum Alignment in Topcolor Models
R. Sekhar Chivukula, Howard Georgi
Topcolor and topcolor-assisted technicolor provide examples of dynamical electroweak symmetry breaking which include top-condensation, thereby naturally incorporating a heavy top q…
Up-Down Asymmetry of Neutral Current Events as a Diagnostic for Nu_mu - Nu-st Versus Nu_mu- Nu_tau Oscillations
John G. Learned, Sandip Pakvasa, J. L. Stone
We show that the asymmetry in the neutral current events (e.g. Nu N -> Nu N pi^0) can be used to discriminate between Nu_mu - Nu_tau and Nu_mu - Nu_st mixing as being responsible f…
A New Model of Topcolor-Assisted Technicolor
Kenneth Lane
I present a model of topcolor-assisted technicolor that can have topcolor breaking of the desired pattern, hard masses for all quarks and leptons, mixing among the heavy and light…
Effective Field Theory for a Three-Brane Universe
Raman Sundrum
A general effective field theory formalism is presented which describes the low-energy dynamics of a 3-brane universe. In this scenario an arbitrary four-dimensional particle theor…
Emission of Axions in strongly magnetized star
Deog Ki Hong
We show that the axion decay constant does not get any correction at any order by external magnetic fields. On the other hand, in the context of the Wilsonian effective action unde…
Narrow Technihadron Production at the First Muon Collider
Estia Eichten, Kenneth Lane, John Womersley
In modern technicolor models, there exist very narrow spin-zero and spin-one neutral technihadrons---, and ---with masses of a few 100 GeV. The large cou…
Technicolor and the First Muon Collider
Kenneth Lane
The motivations for studying dynamical scenarios of electroweak and flavor symmetry breaking are reviewed and the latest ideas, especially topcolor-assisted technicolor, are summar…
