====== TF11: Theory of Neutrino Physics====== Co-Conveners: André de Gouvêa (Northwestern U.), Irina Mocioiu (Penn State U.), Saori Pastore (Washington U.), Louis Strigari (TAMU) **NEW ITEM! ** ===== Mini workshop in preparation for the whitepaper `Theoretical tools for neutrino scattering: interplay between lattice QCD, EFTs, nuclear physics, phenomenology, and neutrino event generators' ===== As Snowmass co-conveners of the topical groups NF06, TF05, TF11, and RF04, we are organizing a three-day workshop together with USQCD, to be held remotely ** August 23–25 from 11 am to 2 pm ET** each day. The main purpose of this workshop is to collect inputs from the community and facilitate the writing of the white paper **“Theoretical tools for neutrino scattering: the interplay between lattice QCD, EFTs, nuclear physics, phenomenology, and neutrino event generators.”** The workshop will have 6 sessions devoted to the following topics: * LQCD calculations for neutrino-nucleus scattering (Coordinator: **Mike Wagman**) * Ab initio nuclear many-body studies for neutrino-nucleus scattering (Coordinator: **Joe Carlson**) * Coherent elastic neutrino-nucleus scattering (Coordinator: **Louis Strigari**) * Neutrino-induced shallow and deep inelastic scattering (Coordinator: **Natalie Jachowicz**) * The needs of the neutrino experimental program (Coordinator: **Kendall Mahn**) * Neutrino event generators (Coordinator: **Steven Gardiner**) In each session, there will be two talks (~20 minutes each) overviewing the current status and vision for the next ten years and assessing the capabilities required for progress, followed by a discussion (~40 minutes) where the community is invited to provide their inputs. At the end of the last day, there will be six parallel sessions devoted to writing the community’s inputs. These working groups will be coordinated by the coordinators indicated above. We welcome your participation in the discussion, which will be reflected in the white paper. If you cannot attend, please fill out this google form https://docs.google.com/forms/d/e/1FAIpQLSfRV6Z5ZzILi7Xhp1fBthM_vX2FVJKbcDJAzfVdcUnTj7aTLg/viewform with any comments or additions. The form will remain open after the workshop. Below please find the workshop’s schedule. **Please register to the workshop** through this indico page https://indico.fnal.gov/e/miniwhitepaper and we will send you a zoom link as we get closer to the date. We hope to see you at the workshop! Sincerely, Snowmass NF06, TF05, TF11, and RF04 Organizers A. Baha Balantekin, Vincenzo Cirigliano, Zohreh Davoudi, Andre L. De Gouvea, Steven Gardiner, Rajan Gupta, Andreas S. Kronfeld, Kendall Mahn, Irina Mocioiu, Saori Pastore, Louis Strigari ===== Neutrino Theory Mini-Workshop ===== The Neutrino Theory topical group is organizing a virtual **Neutrino Theory mini-workshop, September 21-23, 10am-2pm CT.** The meeting will encompass a broad range of topics in neutrino theory, including neutrinos in astrophysics & cosmology, neutrino cross sections, neutrinoless double-beta decay, oscillations, mass and flavor model building, and BSM physics at neutrino experiments. We strongly encourage you to submit abstract. Contributed talks are an excellent opportunity for younger people to contribute and allow one to present and discuss topics that were submitted to Snowmass as LOIs. Contributed talks may also serve as a trigger for LOIs. Your inputs are extremely valuable to the Snowmass effort. To submit an abstract please use https://indico.fnal.gov/event/45039/overview ===== Description===== This topical group will concentrate on the theory of neutrinos physics including: * Exploring the origin of neutrino masses. What is the physics responsible for nonzero neutrino masses? How does this physics connect to other outstanding questions in particle physics and cosmology * Uncovering the fundamental physics of flavor: What precision is required to measure the neutrino oscillation parameters? * Addressing current and future neutrino puzzles: Is there new physics behind the short-baseline anomalies? We will also concentrate on different aspects of theory for neutrino physics including: * Understanding astrophysical neutrino sources and how to extract different neutrino properties from cosmology * Theoretical challenges associated with the computation of neutrino scattering on different targets and at different energy scales, including CEvNS, neutrino-nucleus scattering up to DIS, ultra-high energy neutrinos scattering on the atmosphere or propagating through the Earth * Computation of nuclear-matrix elements for neutrinoless double-beta decays and related processes * Neutrino propagation and flavor evolution in dense environments * Establishing connections between searches for new phenomena at neutrino facilities and new-physics models. ===== LOIs Invitation===== Dear Neutrino Enthusiasts, this is a short message to encourage you to participate in the Snowmass process, which started a couple of months and will end next Summer with a Workshop in Seattle. One way to participate is to submit a letter of interest (LOI). The purpose of letters of interest is to inform the different topical groups about the distinct topics that should be discussed in the community planning exercise that is Snowmass, advertise your willingness to contribute to discussions of the identified topic at different fora, and communicate to the community at large that you are thinking about writing a Snowmass Contributed Paper. LOIs are meant to be short and aimed at a relatively broad audience. They do not require that you report on any existing or on-going original work. For more information, see https://snowmass21.org/loi . The deadline is August 31, 2020 (in about three weeks). If you are planning on submitting an LOI on theoretical topics in neutrino theory, please consider aiming it at both the Neutrino Frontier and the Theory Frontier. Neutrino Physics has a home in several of the Topical Groups in the Theory Frontier, including a dedicated “Theory of Neutrino Physics” topical group TF11. Thanks, André, Irina, Louis, Saori (TF11 conveners) PS - we apologize in advance if you received multiple reminders and requests for Snowmass Letters of Interest. ===== Slides and Minutes===== April 28, 2020 meeting: [[https://indico.fnal.gov/event/24272/contributions/76035/attachments/47318/56805/neutrino_theory.pdf|Neutrino Theory - slides 1]]\\ May 13, 2020 meeting: [[https://indico.fnal.gov/event/43193/contributions/185456/attachments/128201/154993/neutrino_theory_May_13.pdf|Neutrino Theory - slides 2]]\\ June 4th, 2020 NF08+NFXXs meeting: [[https://indico.fnal.gov/event/43894/attachments/129429/157006/NF08June4.pdf| Slide]], [[https://indico.fnal.gov/event/43894/attachments/129429/157005/NF08Minutes.June4th.pdf| Minutes]]\\ July 30th, 2020 Theory Frontier Town Hall - 2nd hour meeting: [[https://indico.fnal.gov/event/44512/sessions/15672/attachments/132193/162306/nu_pheno_TF11_jul30_2020.pdf| Irina]], [[https://indico.fnal.gov/event/44512/sessions/15672/attachments/132193/162312/NucleonsNucleiTF11.pdf| Saori]], [[https://indico.fnal.gov/event/44512/sessions/15672/attachments/132193/162321/TF11_intro.pdf| Andre]] ===== Submitted LOI ===== Here is the list of submitted LOIs to this topic.
