This directory contains some of the physics that I
have worked on:
My thesis was on the SLD measurement of ALR, and the
1996
publication of this measurement , as well as a previous
(1994) paper (my thesis) ,
are available.
A paper on all the polarized asymmetries
is also available.
Langacker and Erler have interpreted this and other precision electroweak
data as limits on Standard Model Higgs.
The ALR measurement depended on the Compton Polarimeter,
which was cross-checked with a Moller Polarimeter. An
interesting effect (Levchuk effect)
due to atomic electron effects was seen to bias Moller
Polarimetry.
The first paper published by KTeV was
on the search for the neutral SUSY hadron, the R0, consisting
of a light gluino paired with a gluon.
I performed a
more sophisticated search
presented at the International Conference
for High Energy Physics
(ICHEP' 98, or the "Rochester Conference")
in Vancouver, which was
published in early '99.

R0 Papers Reference papers for the KTeV light gluino search.
The rare decay K_L-> e+e-mu+mu- was
finally seen with high enough statistics. This decay is important
for determining the CKM matrix element V_td (from K_L->mu+mu-)
This paper is also now published.
We also made a measurement of
the
radiative widths on excited kaons
(including several states
never before measured).
Simply put, the radiative
width gives the likelihood of an excited state decaying by emitting
a photon. In other words, we find out well the picture of the neutral
kaon as a hydrogen-atom-like structure (albeit with strange and
down quarks instead of electron and proton) holds up.
On CDF we have performed one of the most sensitive searches for
the MSSM Higgs Boson, published in Physical Review Letters in 2006.
We searched for
Higgs decaying to tau leptons ,
and in the process greatly
improved the status of tau physics at CDF.
Our work was highlighted in talks by Pier Oddone, director
of Fermilab, as one of the most promising analyses being
performed at the Tevatron.
We have a
website for this analysis, which includes our limit plots
(one of which is also shown in the 2006 Particle Data Book) and
plots showing expected
sensitivity with higher luminosity.
We are currently working on improving the analysis by increasing
our sensitivity to tau leptons, as well as adding more data.
