В обобщённых моделях усложняется структура хиггсовского сектора, вследствие чего появляются дополнительные хиггсовские частицы. Проанализированы теоретические работы ряда авторов и приведены полученные в последние несколько лет экспериментальные данные, возможно, связанные с хиггсовским сектором обобщённых моделей. Кратко обсуждается спонтанное нарушение калибровочной симметрии и возможное объяснение феномена перехода к отрицательному значению квадрата массы скалярного поля, которое используется при спонтанном нарушении. Рассмотрено появление ненулевых значений масс калибровочных бозонов, фермионов и хиггсовских частиц в рамках процедуры спонтанного нарушения калибровочной симметрии. Обсуждается генерация масс частиц в обобщённых моделях. Результаты экспериментальных исследований при высоких энергиях свидетельствуют о возможном существовании нескольких новых скалярных частиц массами от десятков до сотен гигаэлектронвольт, что может подтвердить более сложную структуру скалярного сектора обобщённых моделей по сравнению со структурой скалярного сектора Стандартной модели. Приведённые в обзоре результаты могут быть полезны при планировании и интерпретации результатов экспериментов по поиску скалярных частиц, а также при развитии теоретических обобщённых моделей.</p></abstract><trans-abstract xml:lang="en"><p>The mechanisms of particle mass generation are discussed within the framework of modern models that generalize the Standard Model of electromagnetic, weak, and strong interactions (hereinafter referred to as generalized models). In generalized models, the structure of the Higgs sector becomes more complicated, resulting in additional Higgs particles. Theoretical works of a number of authors are analyzed and experimental data obtained recently, possibly related to the Higgs sector of generalized models, are presented. Spontaneous violation of gauge symmetry and a possible explanation of the phenomenon of transition to a negative value of the square of the mass of a scalar field, which is used in spontaneous violation, are briefly discussed. The appearance of nonzero mass values of gauge bosons, fermions, and Higgs particles is considered in the framework of the procedure of spontaneous violation of gauge symmetry. The generation of particle masses in generalized models is discussed. Recent data indicating the possible existence of several new scalar particles with masses from tens to hundreds of GeV are considered, which may confirm the more complex structure of the scalar sector of generalized models compared to the structure of the scalar sector of the Standard Model. The results presented in the review can be useful in planning and interpreting the results of experiments on the search for scalar particles, as well as in the development of theoretical generalized models.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>масса частицы</kwd><kwd>Стандартная модель</kwd><kwd>спонтанное нарушение симметрии</kwd><kwd>бозон Хиггса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>particle mass</kwd><kwd>Standard model</kwd><kwd>spontaneous symmetry breaking</kwd><kwd>Higgs boson</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор заявляет, что во время подготовки данной рукописи не было получено дополнительных средств, грантов или другой поддержки.</funding-statement><funding-statement xml:lang="en">The author declares that no additional funds, grants, or other support were received during the preparation of this manuscript.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Coleman S.
