В работе представлены недавние результаты поисков новых распадов прелестных частиц, а также результаты поисков новых возбужденных состояний b-адронов. В частности, первое наблюдение возбужденных Ω-b состояний, обнаружение двух узких Лb(6146)0 и Лb(6152)0 состояний, обнаружение Лb**0 состояния, совместного с предсказанием для Лb(2S)0 бариона и обнаружение распада Лb0 → ψ  2S pπ-.</p></abstract><trans-abstract xml:lang="en"><p>   The high statistics collected by the LHCb experiment in proton-proton collisions during Run 1 and 2 of the Large Hadron Collider provides a unique opportunity for study of beauty baryons and to broaden knowledge about their spectroscopy. The paper presents the recent results of searches for new beauty particles decays, as well as the results of searches for new excited states of b-hadrons. In particular, the first observation of excited Ω-b states, the observation of two narrow Лb(6146)0 and Лb(6152)0 states, the observation of new Лb**0 state consistent with the prediction for Лb(2S)0 baryon, and the observation of the Лb0 → ψ  2S pπ- decay are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>физика высоких энергий</kwd><kwd>физика элементарных частиц</kwd><kwd>LHCb</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high energy physics</kwd><kwd>elementary particles physics</kwd><kwd>LHCb</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана Российским фондом фундаментальных исследований (грант № 20-32-90166).
