The CMS Experiment☆ We have recently filled our open postdoc position with the CMS experiment. The Large Hadron Collider began operations in 2008, with proton-proton collisions at 7 TeV center-of-mass energy in 2011 and 8 TeV in 2012. These data allowed the direct observation of Higgs boson production in 2012. We have analyzed these data to search for new physics manifested by long-lived particles decaying to leptons and to perform tests of Standard Model processes using Drell-Yan production of muons. The Large Hadron Collider resumed operations in 2015 with a center-of-mass energy of 13 TeV. |

CMS Detector UpgradesPurdue is preparing for the production of approximately 500 pixel sensor modules with which to construct parts of the Phase-1 upgrade of the Forward Pixel Detector in CMS. We use a robotic assembly process to build these modules which will be used to construct the upgraded detector at Fermilab. Installation of the upgraded pixel detector in CMS is planned during an LHC technical stop at the end of 2016.In collaboration with Fermilab, we have constructed a silicon strip telescope for use at the Fermilab Test Beam Facility with which to characterize rad-hard pixel sensors for future upgrades of the CMS tracker and other novel sensor technologies. |
Charged Lepton Flavor Violation with Mu2eThe Mu2e experiment will search for charged lepton flavor violation by stopping muons on an aluminum target and searching for μ→e. This rare process is sensitive to possible new physics at mass scales up to 104 TeV, well beyond those directly accessible at the LHC. Purdue is collaborating in the construction of the extinction monitor system, which will measure the time structure of the proton beam arriving at the muon production target. |

Heavy flavor physics at CDFThe CDF experiment operated at the Fermilab Tevatron from 2001 to 2012. This experiment pioneered the use at hadron colliders of hardware triggers for selecting decays of hadrons containing bottom quarks which made possible the first unambiguous observation of Bs oscillations. More recently, we measured the angular distribution of muons produced in the decays of Υ mesons which was thought to provide information about different quarkonium production mechanisms. |
Education and OutreachI help organize a QuarkNet summer workshop for high school teachers as part of the Physics Department's outreach program. We provide support for participating teachers throughout the year, including an annual MasterClass activity for high school students, and local support for cosmic ray detector experiments in Indiana high schools. The 2016 QuarkNet workshop will be held during the week of June 27th-July 1st. |
