SUMMARY:Speaker: Barbara Skrzypek (Harvard)- Title:  Ice-Breaking Neutrino Energies: Astrophysical Messengers of Planck-Scale Physics​
DESCRIPTION:This is an In-Person [HYBRID] Event \nLocation: Sessler CR\, 50A-5132 \nDate: July 7\, 2023 \nTime: 12:00- 1:00 PM \nSpeaker: Barbara Skrzypek( Harvard) \nTitle:  Ice-Breaking Neutrino Energies: Astrophysical Messengers of Planck-Scale Physics​  \nAbstract: ​In recent decades\, particle physics has made significant advances in our understanding of high-energy phenomena\, both on theoretical and experimental fronts\, culminating in the current Standard Model (SM) of particle physics. However\, the SM is not a self-contained theory and leaves many questions unanswered; in particular\, it falls short of incorporating dark matter or gravitational forces. Among the implications for this is that\, beyond the quantum gravity scale\, we expect the SM to be replaced with a more fundamental theory giving a quantum description of gravity. As such\, effective theories that arise from this fundamental theory can break certain symmetries that normally hold in the SM\, such as Lorentz- and CPT-invariance . As a result of this\, we expect there to be observables that exhibit low-energy manifestations of these symmetry violations\, and in turn\, this could have implications for neutrinos and other astrophysical messengers. In this talk\, I give an overview of work that I have done in theory\, phenomenology\, and experimental high-energy physics in the area of effective theories of high-energy phenomena. In an effort to characterize the astrophysical neutrinos that IceCube has observed\, I discuss what we can learn about the physics that happens between the production of astrophysical particles and their subsequent detection. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722
