TRIDENT, a neutrino telescope proposed in the South China Sea

A detector near the equator would give a unique viewpoint of the neutrino sky. A site has been found above an abyssal plain at a depth of 3.5 km. The tRopIcal DEep-sea Neutrino Telescope is described at arXiv:2207.04519.

Submarine Navigation with neutrinos

J. Prieto et al. in arXiv:2207.09231 consider using a CEvNS detector in submarines for neutrino Position, Navigation and Timing. They conclude that this application is in the limit of being feasible, but could be realized after some reasonable progress in source and neutrino detector technology.

Secretary of Energy Jennifer Granholm came to ANL to dedicate the new Long Beamline Building at the photon source. Note that there is no hyphen, since both the beamline & building are long. A hyphen is needed in the Long-Baseline Neutrino Facility and Short-Baseline Neutrino Program since the neutrino, facility & program aren't long/short.

DUNE passes important hurdle

In July, the LBNF/DUNE-US Project completed the CD-1RR review with the very positive recommendation that the DOE should proceed to request the formal step of CD-1RR approval. There are a number of good recommendations to prepare the project for the further approval steps at CD-2 and CD-3.

Community Summer Study plans future of US HEP

The 2021/2022 "Snowmass" meeting took place in July. See slides at: https://indico.fnal.gov/event/22303/timetable/?view=standard The goal of the 2-y long process is to identify the most important questions in HEP and the tools and infrastructure required to address them. At the meeting, all frontiers converged on executive summaries representing the views of their communities and provided input needed for P5. In September a draft overall executive summary should be available and in Oct/Nov an ~500 page Snowmass Book will be finalized & ready for submission. The Particle Physics Project Prioritization Panel, a sub-panel of HEPAP, will produce a strategic report for HEP by summer 2023.

Update from NOvA

NOvA showed a new analysis technique for its oscillation results, a Markov Chain Monte Carlo Bayesian Analysis, which allows the results to be scrutinized in new ways. The conclusions about oscillation parameters are the same as the frequentist results. A new sterile nu search included numu events, a wider dm^2 range, dedicated systematics and a covariance matrix fit to 3+1. No sterile signal was seen & a competitive limit on theta_24 was set.

ICARUS starts taking neutrino data

The ICARUS detector, now at Fermilab, has been operating in the Booster Neutrino Beam since February 2020. The top Cosmic Ray Tracker has been included since February 2022. Commissioning concluded at the end of May 2022 & physics data began 7 Jun, after the completion of the 3 m of concrete overburden. That addition reduced the cosmic rate in the top CRT from 600 Hz to 330 Hz.

SBND detector finished

The TPC for the Short-Baseline Neutrino Detector was completed and closed on 13 June. Together with ICARUS (see below), and the completed MicroBooNE experiment, they compose the Short-Baseline Program at Fermilab to try to understand the MiniBooNE anomaly.

Some new things heard at Neutrino 2022 (by speaker)

(Park) The JSNS2 experiment has its first clear kaon decay at rest signal, which it will use to check LSND; (Elliot) BEST reaffirms the Ga anomaly, but saw no dependence on oscillation length; (Gando) KamLAND Zen limits on 0nu2beta decay; (Schonert) War means no Russian 2beta decay isotopes for western countries; (Luk) Daya Bay has improved oscillation parameters; (Vogel) New 235U results essentially explain the previous reactor neutrino anomaly; (Vagins) In June Super-K started adding more Gadolinium, to triple from 0.01% to 0.03% on the way to 0.1% goal; (Caccianiga) Borexino new results on CNO neutrinos; (Bronner) T2K showed reanalysis of the data used for Neutrino 2020, with significant improvements for it all; (All) And, as they say on TV, much more.

Fiscal Year 2023 US LBNF/DUNE budget request

Funding for LBNF/DUNE in FY22 rises slowly, $173M to $189M & $180M in 2023. That aligns with a “conservative” funding profile floated by the DOE last year to address ballooning costs as well as the need to fund LHC upgrades. DOE is currently using an estimate of $3B for the overall cost, with international contributions valued at $660M more. Firm costs will come in 2023 at the earliest.

Neutrino 2072 preview

Neutrino 2022 started with a look back at Neutrino 1972 by Chris Quigg and included a look forward to the possible highlights of Neutrino 2072. A few were: "The study of leptonic CP violation will take on a life of its own; the connection to leptogenesis remains psychological", "Large-scale experiments will hint that some neutrinos decay", and "Detection of cosmogenic neutrinos will fix birth of the first stars".

Նեյտրինոյի օրը ուժի մեջ է, բայց վիրտուալ, հուլիսի 11-ին Սանֆորդի լաբորատորիայի ավանդույթ ՝ այս տարվա նեյտրինոյի օր. Մի հարց առեղծվածը վիրտուալ փորձ կլինի ՝ առցանց զրույցներով, ձեռքերով գործունեություն, խաղեր, արվեստի գործունեություն և գիտության կոմեդիան https://www.sanfordlab.org/article/neutrino-day-goes-virtual

ICARUS դետեկտորը, որը LNGS- ից Ֆերմիլաբ է եկել, մաս է կազմում կարճաժամկետ բազային nu ծրագիրը ՝ անսպասելի արդյունքներին հետևելու համար MiniBooNE- ից: Այն սկսեց հեղուկ Արգոնով լցվել փետրվարին և այժմ լի է 760 տոննա հեղուկ Արգոնով The ICARUS detector, which came to Fermilab from LNGS, is part of the short-baseline nu program to follow up on unexpected results from MiniBooNE. It started filling with liquid Argon in February https://news.fnal.gov/2020/04/liquid-argon-delivery and is now full with 760 tons of liquid Argon. https://icarus.fnal.gov
