Аннотация
Сокращение аномалий в U(1) расширениях минимальной суперсимметричной (СУСИ) стандартной модели (МССМ), которые появляются в качестве низкоэнергетического предела E6 Теории Великого Объединения (ТВО), предполагает наличие экзотической материи. Легчайшее экзотическое нейтралино в этих моделях может быть стабильным, внося вклад в плотность холодной тёмной материи. В работе рассматриваются взаимодействия таких нейтралино с нуклонами в рамках расширения МССМ с дополнительной U(1)N калибровочной симметрией (СE6ССM). В частности, изучаются ограничения на константы взаимодействия данных состояний, которые обусловлены экспериментами по поиску частиц тёмной материи. Полученные результаты обобщаются на другие СУСИ модели с дополнительной U(1) калибровочной симметрией, которые возникают из E6 ТВО.
