Исследуя ход среднего поперечного импульса в зависимости от массы испускаемой частицы, указано на возможность поиска кварковых самородков большой массы – возможных кандидатов на роль частиц темной материи. Предложена также интерпретация спектров мягких фотонов по поперечному импульсу в рр столкновениях с учетом бозона Х17 – новой частицы, возможного кандидата на роль частиц темной материи.</p></abstract><trans-abstract xml:lang="en"><p>In a simple thermodynamic model, the transverse momentum distributions are found for -hyperons produced in pp collisions at ultrarelativistic energies. Studying the behavior of the average transverse momentum depending on the mass of the emitted particle shows that it is possible to search for large mass quark nuggets as possible candidates for the role of dark matter particles. An interpretation of the spectra of soft photons with respect to the transverse momentum in pp collisions is also given taking into account the boson X17, a new particle, a possible candidate for the role of dark matter particles.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ультрарелятивистские столкновения протонов</kwd><kwd>термодинамическая модель</kwd><kwd>рас- пределения по поперечному импульсу</kwd><kwd>кварковые самородки</kwd><kwd>мягкие фотоны</kwd><kwd>бозон Х17</kwd><kwd>модель трубки для КХД2 × КЭД 2</kwd><kwd>частицы темной материи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ultrarelativistic proton collisions</kwd><kwd>thermodynamic model</kwd><kwd>transverse momentum distribution</kwd><kwd>quark nuggets</kwd><kwd>soft photons</kwd><kwd>X17 boson</kwd><kwd>tube model for QCD2 × QED2</kwd><kwd>dark matter particles</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор благодарен В.В.
