PITT PACC Workshop: LHC physics for Run 3

7 Apr 2021, 09:30 → 9 Apr 2021, 21:00 US/Eastern

University of Pittsburgh

The key goal of this virtual workshop is to learn from the latest Run 2 results to provide inspiration for new ideas in Run 3. In addition, a variety of tools will be discussed, including: triggers, machine learning, and reconstruction. We will also allow for ample discussion and have a social hour to allow for meeting new people and forming connections and collaborations.

 

Topics

• Latest results and vision for a variety of physics topics: Higgs, DiHiggs, Non-Standard Model Higgs decays, Dark matter, long-lived particles and Standard Model measurements 

• Development of new tools related to trigger hardware and algorithms 

• Usage of machine learning in reconstruction and analysis of data 

• Lessons learned and how to apply them to Run

Q&A. We plan to use the hand raise option in Zoom (you have to load the participants list to see whether a hand is raised). The session chairs will moderate the Q&A, and ask those with raised hands to unmute and proceed with the question. If it is not possible to speak, there will also be a chat box where a question can be typed and relayed to the speaker by the session chairs.
