Teaching

I am a Physics Professor at the University of Texas, Arlington .

I teach undergraduate and graduate physics classes at UTA. This semester, Spring 2014, I am teaching Freshman Electricity and Magnetism 1442 . My most recent graduate student Ian Howley got his PhD in summer 2013 in under 5 years, working on Higgs searches via tau decay in the DZero Experiment. My post-doc Justin Griffiths, is involved in many aspects of Higgs studies, including a charged Higgs search, Higgs to WW* properties (with Prof. Jaehoon Yu),and VBF Higgs triggering using tagging jets, building on new triggers that we established in the last run. My previous post-doc Edward Sarkisyan-Grinbaum, is working on multiplicity distributions, which describe fundamental aspects of the LHC collisions, and also on ATLAS Forward Proton Detector development. My former student Arnab Pal recently received his Ph.D. in 2012 on a measurement of Single Diffraction on the DZero Experiment at Fermilab, and we are working on the associated paper. Previous students include Pedro Duarte who received his Master's Degree in July 2007, and went to Rice for his Ph. D.; and Dr. Michael Strang graduated in August 2005.

Outreach

I frequently meet with prospective students and give tours of the HEP area in CPB. In 2010, I did some studies for the Texas Rangers on a Josh Hamilton Home Run. There was a fair bit of media attention: here is a UTA summary and here is a local TV video.

Research

My field of research is High Energy Physics. I have been a member of the D0 Experiment at Fermilab in Batavia, IL since 1992. My primary research focus is now the ATLAS Collaboration at the CERN Large Hadron Collider in Geneva, Switzerland, and I had a Faculty Development Leave there in 2008.


ATLAS

My primary research focus over the past several years has been the development of a fast time-of-flight counter for background rejection for LHC proton detectors, for example, the proposed ATLAS Forward Proton detector. The project began as FP420 an R&D effort, studying the feasibility of adding far forward Roman pots to ATLAS and CMS, to aid in discovery physics, such as the Higgs boson. In Fall 2008 we proposed AFP to ATLAS management in a Letter of Intent, in Fall 2009 our proposal received a favorable review, and we submitted a Technical Proposal in May 2011, which was successfully reviewed. In September 2011 the timing system was declared an official ATLAS R&D project, and AFP was included in the official ATLAS Phase 1 LOI , which was endorsed by ATLAS in early 2012. We expect to install this detector in 2014. We are attempting to build a small timing counter with 10 picosecond resolution! Light travels only 3 mm in 10 psec. I am Spokesman of a Fermilab test-beam experiment (T958) to develop and test this detector. I received a Texas ARP grant and a DOE Advanced Detector Research Grant to support this research. I am supervising several undergraduate students in the Picosecond Test Facility (aka the Laser Lab). Here is a picture from our September 2006 test beam run:


Trigger. During my sabbatical in 2008 I became involved in the trigger effort, which seeks to choose the most interesting 300 events out of the millions of collisions each second. For more than two years I led the Trigger Rates group, charged with measuring and evaluating the trigger rates for various trigger menus, as the luminosity increased by more than 5 orders of magnitude
My post-doc Edward Sarkisyan-Grinbaum has been leading multiplicity and correlations studies with early ATLAS data.
I hosted a workshop on fast timing in April 2006: (see web page). I also hosted an FP420 collaboration meeting in March 2007


Homeland Security

I also have been working on an NSF/Homeland Security Grant with UTA Assistant Professor Wei Chen to develop a nanoparticle-based scintillation detector for Homeland Security. We also received a second LARGER grant in this area. This foray into homeland security was expanded into the Forward Physics working group. I gave a status report at the Small-x Workshop. and have been on ATLAS .-->


DZero

One of my physics interests is Quantum Chromodynamics (QCD), especially hard diffraction and rapidity gaps, and I have had several responsibilities in D0 related to these topics:

Co-Leader Forward Proton Detector

I initiated the proposal to add a Forward Proton Detector to D0 for Run II of the Tevatron starting in March 2001 and led the FPD group until it was decommissioned in 2006. Our first paper on elastic scattering is nearly complete and should be published in Spring 2010 The FPD page has all the details. If you are unable to access our web page, you can get some of the information here. The final Roman pot castle design is shown here, along with a picture of Alberto and me (right) looking proudly at the first Roman pot castle at Fermilab.

The FPD was integrated into the D0 readout, with the aid of an NSF MRI grant and a Texas ARP grant. For an overview talk on FPD and diffractive physics, see my Nov. 5, 2003 UTA Colloquium Part I and Part II. Please contact me for further details.

Run I Rapidity Gap Convener

I founded the rapidity gap group Run I at DZero, and we published three papers based on the thesis work of (Brent May, Tracy Taylor Thomas, and Jill Perkins) on rapidity gaps between jets: I also wrote papers on Run I results on diffractive dijets with Kristal Mauritz, and diffractive W/Z with Linda Coney:

I spent many years on the trigger board, which decides which data to write to tape. Previously, I was co-convener of the QCD group and Run I physics analysis group. We brought several QCD analyses to publication. Here is a full list of D0 Publications.

I also convened and chaired the inaugural Run II Trigger Panel which constructed the first Run II trigger list and was a convener of the Diffractive and Color Coherence Working Group at the QCD Run II workshop. I have helped organize major international conferences in Brazil (co-chair of LISHEP 2002.) and at Fermilab (organizing committee for Small-x 2003)
