Open Postdoctoral Position in Experimental Particle Physics

The Physics Department at Indiana University invites applications for a postdoctoral position with the DOE-funded experimental particle/nuclear physics group that is involved in analysis of data from CLEO-c (Cornell) and the design and construction of the GlueX experiment (Jefferson Lab).  The research activities of the group focus on light quark spectroscopy with an emphasis on the search for and study of glueballs and hybrid mesons.  Photoproduction (GlueX) and the charmonium system (CLEO-c) provide rich and complementary environments for carrying out this work.

The successful candidate will be expected to participate in analysis of CLEO-c data and to contribute to ongoing GlueX design and construction efforts at Indiana University.  The group is responsible for construction of the GlueX forward calorimeter and is also active in the software and electronics development for the experiment. A Ph.D. in experimental high-energy or nuclear physics is required.

To apply, send a CV and statement of research interests to:  Professor Matthew Shepherd, Swain West 117, Indiana University, 727 E. Third St., Bloomington, IN 47405 or electronically to mashephe@indiana.edu. Please also arrange to have three letters of reference sent to the same address.  Applications received by June 15 will be assured full consideration.  The position is available immediately and annually renewable assuming satisfactory performance.  Indiana University is an Affirmative Action/Equal Opportunity Employer.

Open Postdoctoral Position in Experimental or Theoretical Particle Physics

Indiana University invites applications for either an experimentalist or phenomenologist to contribute to the development of innovative analysis techniques for the GlueX experiment, a key component of the 12GeV upgrade at Jefferson Laboratory.  GlueX will use a polarized beam of photons to search for exotic configurations of quarks and antiquarks, and will rely on detailed amplitude analyses to isolate these states from their more conventional partners.

As part of a recently funded NSF proposal for Physics at the Information Frontier, Indiana University has assumed responsibility for the creation of a unique and flexible interface between experiment and phenomenology, offering phenomenologists an unprecedented level of access to experimental data.  The post-doctoral researcher will aid in this effort.  Existing experimental data from the CLEO-c experiment at Cornell and Brookhaven's E852,
besides offering important physics topics in their own right, will serve as a testbed for the development of GlueX analysis tools.  The candidate will work with a collaboration of experimentalists and phenomenologists at Indiana University, Carnegie Mellon University, the University of Connecticut, and Jefferson Laboratory.

This position is renewable for up to three years with the starting date negotiable.  The minimum requirement is a Ph.D. in nuclear/particle physics and programming experience. Applicants should send a curriculum vitae and summary of research interests, and arrange to have three letters of recommendation sent to: Ryan Mitchell, Indiana University, 727 E. Third St., Bloomington, IN 47405-7105 or electronically to: remitche@indiana.edu. Review of applications will begin immediately with applications being accepted until the position is filled.

Research Overview

The Task D group research is focused on understanding the spectrum of light quark mesons. In particular, we are searching for the gluonic degrees of freedom in this spectrum. This experimental information is a key ingredient in obtaining a quantitative understanding of the confinement mechanism in QCD. Recent theoretical advances in QCD and in particular Lattice QCD make it possible now to predict the masses of gluonic excitations.

Task D research is supported by the DOE Office of Nuclear Physics and College of Arts & Sciences and the Office of the Vice-President for Research at IU.

Task D also collaborates closely with Prof. Adam Szczepaniak and his students from the Nuclear Theory Center and with Prof. Geoffrey Fox who heads the Community Grids Lab of IU's Pervasive Technology Lab.

The physics of Task D also overlaps strongly with the lattice QCD work headed by Prof. Steve Gottlieb of Task B.
