Уважаемые коллеги!

На заседании Ученого совета в пятницу  27 января в 11:30 будет заслушан
доклад:

Н.Н. Николаев
*Спин в накопителях как аксионная антенна*

Аксионы, предложенные Печчеи, Куинн, Вилчеком и Вайнбергом как решение
загадки СР-инвариантности КХД, широко обсуждаются как кандидат в темную
материю. Как было указано Колоколовым и др., осциллирующие галактические
аксионные поля порождают псевдомагнитное поле, пропорциональное скорости
движения спина относительно центра Галактики. Околосветовая скорость
частиц в накопителях усиливает эти поля на три порядка по сравнению с
полями, действующими на спины в конденсированных средах в лаборатории.
Будут представлены результаты первого эксперимента по поиску аксионов на
накопителе СOSY в Юлихе, и обсуждены перспективы экспериментов на
коллайдере NICA в Дубне.
Краткий обзор работ: 1) S. Karanth, ... , N.N. Nikolaev etc (JEDI
Collaboration), "First Search for Axion-Like Particles in a Storage Ring
Using a Polarized Deuteron Beam@, arXiv:2208.07293; 2) N.N. Nikolaev,
"Spin of protons in NICA and PTR storage rings as an axion antenna",
Письма в ЖЭТФ, 115(11), 683-684 (2022) [JETP Letters, 115(11), 639-643
(2022)]
