Snowmass Theory Frontier: Effective Field Theory
Matthew Baumgart, Fady Bishara, Tomas Brauner +34
We summarize recent progress in the development, application, and understanding of effective field theories and highlight promising directions for future research. This Report is p…
Structure Function Sum rules for Systems with Large Scattering Lengths
Walter D. Goldberger, Ira Z. Rothstein
We use a dispersion relation in conjunction with the operator product expansion (OPE) to derive model independent sum rules for the dynamic structure functions of systems with larg…
Standard Model couplings and collider signatures of a light scalar
JiJi Fan, Walter D. Goldberger, Andreas Ross +1
The electroweak symmetry breaking (EWSB) sector of the Standard Model can be far richer and more interesting than the usual single scalar doublet model. We explore scenarios where…
Light scalar at LHC: the Higgs or the dilaton?
Walter D. Goldberger, Benjamin Grinstein, Witold Skiba
It is likely that the LHC will observe a color- and charge-neutral scalar whose decays are consistent with those of the Standard Model (SM) Higgs boson. The Higgs interpretation of…
Les Houches Lectures on Effective Field Theories and Gravitational Radiation
Walter D. Goldberger
These lectures give an overview of the uses of effective field theories in describing gravitational radiation sources for LIGO or LISA. The first lecture reviews some of the standa…
Spin dependent masses and Sim(2) symmetry
JiJi Fan, Walter D. Goldberger, Witold Skiba
Recently, Cohen and Glashow pointed out that all known experimental tests of relativistic kinematics are consistent with invariance of physics under the four-parameter subgroup Sim…
Systematics of Coupling Flows in AdS Backgrounds
Walter D. Goldberger, Ira Z. Rothstein
We give an effective field theory derivation, based on the running of Planck brane gauge correlators, of the large logarithms that arise in the predictions for low energy gauge cou…
Warped Supersymmetric Grand Unification
Walter D. Goldberger, Yasunori Nomura, David R. Smith
We construct a realistic theory of grand unification in AdS_5 truncated by branes, in which the unified gauge symmetry is broken by boundary conditions and the electroweak scale is…
Phenomenology of a Stabilized Modulus
Walter D. Goldberger, Mark B. Wise
We explore the phenomenology of a stabilized modulus field in the Randall-Sundrum scenario. It is found that if the large separation between branes arises from a small bulk scalar…
Modulus Stabilization with Bulk Fields
Walter D. Goldberger, Mark B. Wise
We propose a mechanism for stabilizing the size of the extra dimension in the Randall-Sundrum scenario. The potential for the modulus field that sets the size of the fifth dimensio…
Bulk Fields in the Randall-Sundrum Compactification Scenario
Walter D. Goldberger, Mark B. Wise
Recently, Randall and Sundrum proposed a solution to the hierarchy problem where the background spacetime is five dimensional. There are two 3-branes, and the mass scale for fields…
Semileptonic B Decays as a Probe of New Physics
Walter D. Goldberger
Physics beyond the Standard Model could be measured indirectly, through its effects on Standard Model observables. One place to look for such effects is in the semileptonic decays…
