Summary of the Very Large Hadron Collider Physics and Detector Workshop

G. Anderson, U. Baur, M. Berger +16

One of the options for an accelerator beyond the LHC is a hadron collider with higher energy. Work is going on to explore accelerator technologies that would make such a machine fe…

General constraints on light resonances in a strongly coupled symmetry breaking sector

R. S. Chivukula, F. M. Renard, C. Verzegnassi

In this paper we consider the information that can be obtained about a strongly-interacting symmetry breaking sector from precision measurements of four-fermion processes at LEP2 o…

Towards an Effective Particle-String Resolution of the Cosmological Constant Problem

Raman Sundrum

The Cosmological Constant Problem is re-examined from an effective field theory perspective. While the connection between gravity and particle physics has not been experimentally p…

The Significance of the Heavy Top Quark

E. H. Simmons

Experiment shows that the top quark is far heavier than the other elementary fermions. This finding has stimulated research on theories of electroweak and flavor symmetry breaking…

Numerical Approaches to High Energy Electroweak Baryon Number Violation Above and Below the Sphaleron Barrier

Claudio Rebbi, Robert Singleton

We review some promising numerical techniques for calculating high energy baryon number violating cross sections in the standard model. As these lectures are designed to be self- c…

Counting 4 pi 's in Strongly Coupled Supersymmetry

Andrew G. Cohen, David B. Kaplan, Ann E. Nelson

We extend the "naive dimensional analysis" arguments used in QCD for estimating the strengths of operators in chiral Lagrangians to strongly coupled supersymmetric theories. In par…

Flavor from Strongly Coupled Supersymmetry

David B. Kaplan, Francois Lepeintre, Martin Schmaltz

Strongly coupled supersymmetric theories can give rise to composite quarks and leptons at low energy. We show that the internal structure of these particles can explain the origin…

Tevatron Constraints on Topcolor-Assisted Technicolor

Yumian Su, Gian Franco Bonini, Kenneth Lane

We study the constraints on models of topcolor-assisted technicolor arising from measurements of high- jets and high-mass lepton pairs at the Tevatron collider. Existing data…

Finding Low-Scale Technicolor at Hadron Colliders

Estia Eichten, Kenneth Lane, John Womersley

In multiscale and topcolor-assisted models of walking technicolor, relatively light spin-one technihadrons and exist and are expected to decay as …

Reparameterization Invariance to all Orders in Heavy Quark Effective Theory

Raman Sundrum

Heavy Quark Effective Theory splits a heavy quark momentum into a large fixed momentum and a variable residual momentum, p = m_Q v + k. It thereby suffers a redundancy of descripti…

Flavor Physics and the Triviality Bound on the Higgs Mass

R. S. Chivukula, B. A. Dobrescu, E. H. Simmons

The triviality of the scalar sector of the standard one-doublet Higgs model implies that this model is only an effective low-energy theory valid below some cut-off scale . The u…

B - L Mediated Supersymmetry Breaking

Bogdan A. Dobrescu

I present a realistic model of dynamical supersymmetry breaking, in which a gauge interaction communicates supersymmetry breaking to the standard fields. A distinctive…

Hadronic String from Confinement

Raman Sundrum

The existence of hadronic string is derived as a consequence of confinement in QCD. A state of ``stretched glue'', created by a Polyakov loop operator, is shown to have translation…

New Gauge Interactions and Single Top Quark Production

E. H. Simmons

Extensions of the standard model that include new W bosons or extended technicolor gauge bosons can predict sizeable changes in the rate of single top quark production, even when c…
