Экспериментальные данные по изучению мезонов в ядерной среде являются востребованными для развития теоретических моделей, описывающих процессы в области непертурбативной квантовой хромодинамики (КХД). В эксперименте Гиперон-М на ускорителе У70 проводятся измерения масс и ширин нейтральных мезонов, рождающихся в мезон-ядерных взаимодействиях на различных ядрах. В данной работе описана методика прецизионного измерения параметров нейтральных мезонов, представлены результаты по измерению массы и ширины ω(782) -мезона и предварительные результаты по измерению массы и ширины f (1270) -мезона. Измерения указывают на отсутсвие зависимости изучаемых величин от ядерной среды.</p></abstract><trans-abstract xml:lang="en"><p>According to modern theories parameters of neutral mesons such as their mass and width are tightly related to medium in which mesons are present. Experimental data on the study of mesons in a nuclear medium are in demand for the development of theoretical models describing processes in the field of nonperturbative quantum chromodynamics (QCD). In the Hyperon-M experiment at the U70 accelerator, measurements are made of the masses and widths of neutral mesons produced in meson-nuclear interactions on various nuclei. This paper describes a technique for precision measurement of the parameters of neutral mesons, presents the results on the measurement of the mass and width of the ω(782)-meson and preliminary results on the measurement of the mass and width of the f (1270)-meson. The measurements indicate that there is no dependence of the quantities under study on the nuclear environment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модификация</kwd><kwd>масса</kwd><kwd>ширина</kwd><kwd>мезоны</kwd><kwd>мезон-ядерные взаимодейтсвия</kwd><kwd>У70</kwd></kwd-group><kwd-group xml:lang="en"><kwd>modification</kwd><kwd>mass</kwd><kwd>width</kwd><kwd>mesons</kwd><kwd>meson-nucleus interactions</kwd><kwd>U70</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 18- 32-00266.</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">Goldstone J., Salam A., Weinberg S. // Phys.
