Title:Alignmentand calibration in CMS Detector Performance and Offline Data Processing
Speaker:Dr. Tong-Guang Cheng, Purdue University Northwest
Abstract:Fast and efficient methodsfor the calibration and the alignment of the detector are a key asset toexploit the physics potential of the Compact Muon Solenoid (CMS) detector andto ensure timely preparation of results for conferences and publications. Thepresentation will review the online and offline workflows designed to align andcalibrate the CMS detector in Run-2 (2015-2018) and its impact on CMS detector performanceand offline data processing for physics analysis. The development in terms ofalignment, calibration services planned during the Long Shutdown in 2019-2020 will also be discussed.
Dr. Tong-GuangCheng obtained his Ph. D. degree from University of Florida (USA) in 2014 underthe supervision of Dr. Guenakh Mistelmaker and Dr. Andrey Korytov. He wasworking as a postdoc in Institute of High Energy Physics (China) during2014-2016 and then moved to Purdue University Northwest as a postdoc fellowtill now. He has been heavily involved in the physics analyses and madesignificant contributions, such as Higgs Discovery , Higgs propertymeasurements and heavy resonance search. He is now a L2 convenor of Physics andPerformance Dataset Group in CMS collaboration, in charge of the Alignment andCalibration Tasks.
