Steve Sharpe
Professor of Physics
Department of Physics, University of Washington
Steve Sharpe joined the
particle theory group in the
Physics Department at the University of Washington in 1988.
Current research interests include
lattice gauge theory, and in particular the calculation of weak matrix
elements, and hadron spectroscopy. Current graduate student is
Andrew Lytle. Previous graduate students
are Keith Clay (joint with Steve Ellis, presently on faculty
at Green River Community College), Yan Zhang (was postdoc at Beijing U.,
present whereabouts unknown),
Noam Shoresh (joint with David B. Kaplan, postdoc at Boston U, now
postdoc at Harvard center for genomics research),.
Ruth Van de Water (presently postdoc at Fermilab)
and Jackson Wu (presently postdoc at Triumf, Vancouver).

Publications
-
I organized a summer school at the INT in 2007 on
``Lattice QCD and its applications''.
I am a member of the executive committee of the
-
USQCD
collaboration, which has obtained support from DOE
for computational resources and support.
-
I am a co-PI on a
SciDAC2
(Scientific Discovery through Advanced computing---round 2) proposal
aimed at creating a national infrastructure for lattice gauge computing.
-
With collaborators Weonjong Lee and Chulwoo Jung,
I am calculating the kaon B-parameter and other matrix elements using
improved staggered fermions, using USQCD resources.
The project web page is here .
-
UW graduate student Andrew Lytle and
I are calculating matching factors using
non-perturbative renormalization for improved
staggered fermions.

Updated lectures on
"Applications of chiral perturbation theory to lattice QCD"
.
These lectures
describe the use of effective field theories to extrapolate results
from the parameter region where numerical simulations of lattice QCD
are possible to the physical parameters (physical quark masses,
infinite volume, vanishing lattice spacing, etc.). After a brief
introduction and overview, I discuss three topics:
-
(1)
Chiral
perturbation theory in the continuum, and lessons for lattice
calculations;
-
(2)
The inclusion of
discretization effects into chiral perturbation theory, focusing on
the application to Wilson and twisted-mass lattice fermions;
-
(3)
Extending chiral perturbation theory to describe partially quenched
QCD, and (this is new) a discussion of the relationship of the possible
ambiguity in the definition of $m_u=0$ and the existence of continuum
PQ theories.
