KamLAND and solar neutrino data eliminate the LOW solution

V. Barger, D. Marfatia

The KamLAND reactor antineutrino experiment has detected a 3.4σflux suppression relative to the expectation if no neutrino oscillations occur. We combine KamLAND data with solar ne…

Where is the Higgs boson?

A. Aranda, C. Balazs, J. L. Diaz-Cruz

Electroweak precision measurements indicate that the standard model Higgs boson is light and that it could have already been discovered at LEP 2, or might be found at the Tevatron…

The Top Quark: Experimental Roots and Branches of Theory

E. H. Simmons

The CDF and D0 experiments at the Fermilab Tevatron have discovered the top quark and provided first measurements of many of its properties. The small top sample gathered by Run I…

Models of Flavor with Discrete Symmetries

Alfredo Aranda

In an attempt to understand the observed patterns of lepton and quark masses, models invoking a flavor symmetry , under which the Standard Model generations are charged, have…

How two neutrino superbeam experiments do better than one

V. Barger, D. Marfatia, K. Whisnant

We examine the use of two superbeam neutrino oscillation experiments with baselines $\lsim 1000$ km to resolve parameter degeneracies inherent in the three-neutrino analysis of suc…

Introducing the Little Higgs

Martin Schmaltz

Little Higgs theories are an exciting new possibility for physics at TeV energies. In the Standard Model the Higgs mass suffers from an instability under radiative corrections. Thi…

The Collider Phenomenology of Technihadrons in the Technicolor Straw Man Model

Kenneth Lane, Stephen Mrenna

We discuss the phenomenology of the lightest SU(3)_C singlet and non-singlet technihadrons in the Straw Man Model of low-scale technicolor (TCSM). The technihadrons are assumed to…

Deconstructing Dimensional Deconstruction

Kenneth Lane

Dimensional deconstruction (DD) abstracts from higher dimensional models features of related 4--dimensional ones. DD was proposed in Refs.[1,2,3] as a scheme for constructing model…

Cosmological Sign of Neutrino CP Violation

P. H. Frampton, S. L. Glashow, T. Yanagida

It is shown how, in a class of models, the sign of the baryon number of the universe can be related to CP violation in neutrino oscillation experiments.

Pion dispersion relation at finite density and temperature

A. Ayala, P. Amore, A. Aranda

We study the behavior of the pion dispersion relation in a pion medium at finite density and temperature. We introduce a pion chemical potential to describe the finite pion number…

The Littlest Higgs

N. Arkani-Hamed, A. G. Cohen, E. Katz +1

We present an economical theory of natural electroweak symmetry breaking, generalizing an approach based on deconstruction. This theory is the smallest extension of the Standard Mo…

The Minimal Moose for a Little Higgs

N. Arkani-Hamed, A. G. Cohen, T. Gregoire +3

Recently a new class of theories of electroweak symmetry breaking have been constructed. These models, based on deconstruction and the physics of theory space, provide the first al…

Electroweak Limits on Non-Universal Z' Bosons

R. S. Chivukula, E. H. Simmons

Many types of physics beyond the standard model include an extended electroweak gauge group. If these extensions are associated with flavor symmetry breaking, the gauge interaction…

Off--axis Beams and Detector Clusters: Resolving Neutrino Parameter Degeneracies

V. Barger, D. Marfatia, K. Whisnant

There are three parameter degeneracies inherent in the three--neutrino analysis of long--baseline neutrino experiments. We develop a systematic method for determining whether or no…

B-Meson Gateways to Missing Charmonium Levels

Estia J. Eichten, Kenneth Lane, Chris Quigg

We outline a coherent strategy for exploring the four remaining narrow charmonium states [$η_{c}^{\prime}(2\slj{1}{1}{0})$, $h_{c}(1\slj{1}{2}{1})$, $η_{c2}(1\slj{1}{3}{2})$, and $…

Bosonic Supersymmetry? Getting Fooled at the LHC

Hsin-Chia Cheng, Konstantin T. Matchev, Martin Schmaltz

We define a minimal model with Universal Extra Dimensions, and begin to study its phenomenology. The collider signals of the first KK level are surprisingly similar to those of a s…

No-go for detecting CP violation via neutrinoless double beta decay

V. Barger, S. L. Glashow, P. Langacker +1

We present a necessary condition on the solar oscillation amplitude for CP violation to be detectable through neutrinoless double beta (0νββ) decay. It depends only on the fraction…

Radiative Corrections to Kaluza-Klein Masses

Hsin-Chia Cheng, Konstantin T. Matchev, Martin Schmaltz

Extra-dimensional theories contain a number of almost degenerate states at each Kaluza-Klein level. If extra dimensional momentum is at least approximately conserved then the pheno…

Strong Dynamics and Electroweak Symmetry Breaking

Christopher T. Hill, Elizabeth H. Simmons

The breaking of the electroweak symmetry, and origin of the associated ``weak scale,'' may be due to a new strong interaction. Theoretical developments over the past decade have le…
