Events on Thursday, May 6th, 2021
- Cosmology Journal Club
- Time: 12:00 pm - 1:00 pm
- Abstract: Each week, we start with a couple scheduled 15 minute talks about one's research, or an arXiv paper. The last 30 minutes will typically be open to the group for anyone to discuss an arXiv paper.
All are welcome and all fields of cosmology are appropriate.
Contact Ross Cawthon, cawthon@wisc, for more information.

- Abstract: Every time researchers have pushed the energy boundary in particle physics we have found something new about our Universe. Recently, IceCube has demonstrated that Neutrino Telescopes can use neutrinos from the cosmos as excellent tools to continue this exploration. The Pacific Ocean Neutrino Explorer (P-ONE) is a proposed initiative to construct one of the largest neutrino telescopes deep in the northern Pacific Ocean off the coast of British Columbia. To overcome the challenges of a deep-sea installation, we have deployed two prototype mooring lines STRAW and STRAW-b in 2018 and 2020. These provide continuous monitoring of optical water properties at a potential detector site in the Pacific. In this talk I will cover the latest results from these prototype lines and plans to deploy P-ONE off the coast of Vancouver Island.

- Stop, hammer time! Using novel tools to nail down the top squark after Run 2
- Time: 3:30 pm - 4:30 pm
- Place: Zoom:
- Speaker: Dr. Daniel Spitzbart, Boston University
- Abstract: Top squarks ("stops"), the superpartners of top quarks, could be a key to answer questions about the nature of the Higgs boson mass and shed light on the origin of dark matter. Predicted to have a mass that is accessible at the LHC themselves they are a prime target in searches for supersymmetry.
New analysis techniques were inspired and facilitated by the large available data set from Run 2 of the LHC, leading to unprecedented sensitivity to top squarks with masses up to 1.3 TeV.
I will present novel methods based on machine learning and elaborate algorithms, and show the latest results from these searches. By combining a comprehensive set of individual analysis channels we are able to further tighten these constraints, leading to results that will set a legacy for years to come.
