Perceptual phenomenology
I am looking at an apple. The apple has a lot of properties and some, but
not all, of these are part of my phenomenology at this moment: I am aware of these properties. And some, but not all, of these properties that I am aware of are part of my perceptual (or sensory) phenomenology. If I am attending to the apple’s color, this property will be part of my perceptual phenomenology. The property of being a granny smith apple from Chile is unlikely to be part of my perceptual phenomenology.
Here are two problems for anyone who is interested in conscious experience
in general, and perceptual experience in particular:
(a) How can we tell which properties are part of our phenomenology and
which ones are not?
(b) How can we tell which properties are part of our perceptual phenomenology and which ones are part of our non-perceptual phenomenology?
I will focus on (b) in this paper. My aim is twofold: I propose a methodology for answering the question of which properties are part of our perceptual phenomenology and I provide an example for how this methodology could be applied
Coloron Phenomenology
A flavor-universal extension of the strong interactions was recently proposed
in response to the apparent excess of high- jets in the inclusive jet
spectrum measured at the Tevatron. This paper studies the color octet of
massive gauge bosons (`colorons') that is present in the low-energy spectrum of
the model's Higgs phase. Constraints from searches for new particles decaying
to dijets and from measurements of the weak-interaction parameter imply
that the colorons must have masses greater than 870-1000 GeV. The implications
of recent Tevatron data and the prospective input from future experiments are
also discussed.Comment: 13 pages, 4 embedded Postscript figures, LaTeX, full postscript

Supersymmetry Phenomenology
This is a very pedagogical review of supersymmetry phenomenology, given at
ICTP Summer School in 1999, aimed mostly at students who had never studied
supersymmetry before. It starts with an analogy that the reason why
supersymmetry is needed is similar to the reason why the positron exists. It
introduces the construction of supersymmetric Lagrangians in a practical way.
The low-energy constraints, renormalization-group analyses, collider
phenomenology, and frameworks of mediating supersymmetry breaking are briefly
discussed.Comment: 40 pages, uses psfi
