Dynamically broken Topcolor at Large-N
Hael Collins, Aaron K. Grant, Howard Georgi
We analyze a model of dynamically broken topcolor in the limit in which the number of colors is large. We show that the second order nature of the phase transition, necessary for t…
Precision Tests of Electroweak Physics
Tatsu Takeuchi, Will Loinaz, Aaron K. Grant
We review the current status of precision electroweak measurements and the constraints they impose on new physics. We perform a model independent analysis using the STU-formalism o…
An analysis of Precision Electroweak Measurements: Summer 98 Update
Aaron K. Grant, Tatsu Takeuchi
We update our analysis of precision electroweak measurements using the latest data announced at Moriond, March 1998. Possible oblique corrections from new physics are parametrized…
The difficulties involved in calculating
Tatsu Takeuchi, Aaron K. Grant, Mihir P. Worah
We discuss the difficulties that arise when one tries to calculate using dispersion relations.
An Analysis of Non-Oblique Corrections to the Vertex
Tatsu Takeuchi, Aaron K. Grant, Jonathan L. Rosner
We present a model--independent analysis of the vertex, with the aim of constraining contributions of new physics to the left- and right--handed couplings of the .…
Quarkonium and Power Law Potentials
Aaron K. Grant, Jonathan L. Rosner
The spectra and decay rates of and levels are well described, for the most part, by a power-law potential of the form , where $α…
