Welcome to PHYS 6B and PHYS 291D students!
In Winter 2022 quarter, I will be teaching two courses: Introductory Physics II and Experimental High-Energy Collider Physics.
All of the information for both courses is already in the Canvas LMS.
Observation of Higgs bosons decaying to bottom quarks
The detection of the Higgs decay to bottom quarks was announced jointly by the ATLAS and CMS experiments at CERN, the European particle physics lab in Geneva, Switzerland.
After several years of refining their techniques and gradually incorporating more data, both experiments finally saw evidence of the H→bb production that exceeds the 5-sigma threshold of statistical significance typically required to claim a discovery.
Measurement of Higgs bosons produced via vector boson fusion
The requirement of a high-pT photon associated with VBF Higgs production results in a remarkable background suppression because the diagrams with emission from the initial-state quark and final-state quark interfere destructively.
For the same reason, this signature provides a unique opportunity to disentangle the W and Z boson contributions to vector boson fusion
Power and data transmission for the ATLAS pixel detector upgrade
The Type-I services are the essential link between the Patch Panel 0 inside the ITk detector volume and the Patch Panel 1 on the ITk bulkhead.
These services carry low-voltage power and high-voltage sensor bias voltage in addition to Detector Control System data and monitoring interlock signals.
The services are designed with very low mass, very small cross-sectional area, and very high radiation and temperature tolerance.
