IceCube at Neutrino 2020
Today kicks off the second week of the 29th biennial Neutrino conference, the world’s biggest conference in neutrino physics. Due to the coronavirus pandemic, Neutrino 2020 is being held virtually over the course of two weeks, starting last Monday, June 22, and ending this Friday, July 2. According to a press release by the Department of Energy’s Fermilab, host of Neutrino 2020 alongside the University of Minnesota, “The change has allowed triple the typical number of participants to sign up for the conference and resulted in an increased number of abstracts submitted for the poster session.”
The IceCube Collaboration has a robust cohort presenting at the conference. Three IceCube collaborators will give plenary talks, and there are 30 virtual posters by collaborators.
IceCube’s PI, Francis Halzen of the University of Wisconsin–Madison, gave the first headline talk of Neutrino 2020 on Monday, June 22, called “Neutrinos in the era of multi-messenger astronomy.” Halzen discussed the future role for neutrinos in multimessenger astronomy—the coordinated collection of different kinds of signals (such as those from gravitational waves) from beyond our solar system that, when combined, provide a new window to the cosmos.
Shortly after that, Summer Blot of DESY gave a talk titled “Neutrino oscillation measurements with IceCube” about physics with the IceCube DeepCore array, which, during its ten years of full operation, has provided a rich sample of atmospheric and astrophysical neutrinos that can be used to study a wide range of physical phenomena. In her talk, Blot discussed the latest measurements of atmospheric neutrino oscillations from IceCube DeepCore, which are performed at the highest energies and over very long baselines. And while IceCube hasn’t yet seen significant indications of new physics that these data can be used to search for, we have derived world-leading constraints on nonstandard interactions and sterile neutrinos. Blot also discussed the planning and construction of the IceCube Upgrade that, when deployed in 2022-23, will provide unprecedented sensitivity to atmospheric neutrino oscillations at the GeV scale and more generally enhance the overall science program of IceCube through improved detector calibration systems.
Tomorrow, Tuesday, June 30, Marcos Santander of the University of Alabama will present his talk, “Recent results in high-energy neutrino astrophysics with IceCube,” in which he will summarize recent results from IceCube’s neutrino astrophysics program and present an outlook for future developments. High-energy neutrinos are unique probes of the hadronic sky, and their observation enables searches for cosmic particle accelerators and provides a natural neutrino beam with energies and baselines far greater than what is available on Earth. IceCube’s observations of astrophysical neutrinos in the TeV-PeV range have been major breakthroughs for the field and have motivated a wide range of studies within IceCube aimed at characterizing the astrophysical flux. Searching for neutrino sources relies on identifying neutrino self-clusterings, correlating neutrino measurements in time and space with multiwavelength and multimessenger observations, and alerting the astrophysical community to new high-energy neutrino detections to enable counterpart identifications.
