Effective operators and vacuum instability as heralds of new physics
C. P. Burgess, V. Di Clemente, J. R. Espinosa
For a light enough Higgs boson, the effective potential of the Standard Model develops a dangerous instability at some high energy scale, Lambda, signalling the need for new physic…
R_b and New Physics: A Comprehensive Analysis
P. Bamert, C. P. Burgess, J. M. Cline +2
We survey the implications for new physics of the discrepancy between the LEP measurement of and its Standard Model prediction. Two broad classes of models are considered: ($…
The Effective Use of Precision Electroweak Measurements
C. P. Burgess
Several reasonably model-independent formulations of the implications of new physics for precision electroweak measurements have been developed over the past years, most notably by…
Naturally Degenerate Neutrinos
P. Bamert, C. P. Burgess
The solar neutrino problem, atmospheric neutrino problem, and the existence of hot dark matter can all be economically accounted for using only the three known neutrinos if these n…
A Global Fit to Extended Oblique Parameters
C. P. Burgess, S. Godfrey, H. Konig +2
The STU formalism of Peskin and Takeuchi is an elegant method for encoding the measurable effects of new physics which couples to light fermions dominantly through its effects on e…
A New Class of Majoron-Emitting Double-Beta Decays
C. P. Burgess, J. M. Cline
Motivated by the excess events that have recently been found near the endpoints of the double beta decay spectra of several elements, we re-examine models in which double beta deca…
A Common Explanation for the Atmospheric, Solar-Neutrino and Double Beta Decay Anomalies
C. P. Burgess, Oscar Hernandez
We make a number of small changes, including correcting an error in our heavy-neutrino decay rate. None of our analysis is changed, either in substance or detail.
Bounding Anomalous Gauge-Boson Couplings
C. P. Burgess, Stephen Godfrey, Heinz König +2
In this version we have corrected some minor errors in the tables, corrected typos, and added a reference. We have also updated our comparison with earlier workers. Figures are now…
Loops, Cutoffs and Anomalous Gauge Boson Couplings
David London, C. P. Burgess
We discuss several issues regarding analyses which use loop calculations to put constraints on anomalous trilinear gauge boson couplings (TGC's). Many such analyses give far too st…
New Neutrino Physics Without Fine Tuning
C. P. Burgess, James M. Cline, Markus Luty
We show how a 17 keV neutrino, the solar neutrino problem, and the atmospheric muon-neutrino deficit could all be the low-energy residues of the same pattern of lepton-number break…
Light Spin-One Particles Imply Gauge Invariance
C. P. Burgess, David London
Recently, calculations which consider the implications of anomalous trilinear gauge-boson couplings, both at tree-level and in loop-induced processes, have been criticized on the g…
A Natural Framework for Solar and 17 keV Neutrinos
C. P. Burgess, J. Cline, Markus Luty
Motivated by recent experimental claims for the existence of a 17 keV neutrino and by the solar neutrino problem, we construct a class of models which contain in their low-energy s…
Uses and Abuses of Effective Lagrangians
C. P. Burgess, David London
Motivated by past and recent analyses we critically re-examine the use of effective lagrangians in the literature to constrain new physics and to determine the `physics reach' of f…
