Justin Vandenbroucke turns smartphones into pocket cosmic ray detectors

With a simple app addition, Android phones, and likely other smartphone brands in the not-too-distant future, can be turned into detectors to capture the light particles created when cosmic rays crash into Earth’s atmosphere.

CMS Upgrades approved

Phase-1 upgrades for the CMS detector, including the work of the UW CMS Trigger Team, are approved for construction with the attainment of the DOE Critical Decision 2/3 for a $43M project. Profs. Wesley Smith and Sridhara Dasu are leading the calorimeter trigger upgrade efforts at UW. The success is in part due to excellent hardware and firmware designed by UW engineers. Featured here is this year’s UW academic staff award winner Mr. Tom Gorski’s CTP7 board, sporting the highest-end Field Programmable Gate Arrays, Virtex-7 and ZYNQ from Xilinx Inc.

Using the Higgs boson to search for clues

Wisconsin postdoc Maria Cepeda and graduate student Aaron Levine were instrumental in this CMS study of non-standard model Higgs couplings in search of clues regarding new physics.

CMS presents evidence for Higgs coupling to fermions

Wisconsin group played a leading role in presenting evidence for Higgs coupling to fermions. Graduate students Joshua Swanson and Isobel Ojalvo, undergraduate student Stephane Coopertein did crucial work on Higgs decays to tau-leptons. Prof. Sridhara Dasu co-led the CMS group that performed this analysis.

CMS Trigger Upgrades

UW physicists are hard at work upgrading the trigger system for the CMS experiment at the LHC, which is in the middle of a maintenance period in preparation for higher energy collisions in 2016. Graduate student Tom Perry takes a break from this work to give the public an explanation of what the trigger system is, using a bowl of party mix.
