Партоны рассматриваются как возбуждения на орисфере релятивистского пространства импульсов. Показано, что в рамках модели устанавливается общий вид зависимости радиуса корреляций от множественности заряженных частиц, допускающей описание экспериментальных данных. </p></abstract><trans-abstract xml:lang="en"><p>Purpose of the research is to explain the peculiarities of the dependence of the Bose – Einstein correlation radius (size of the production region) on the multiplicity of produced charged particles at the energy in the center of mass system 7 и 13 ТeV in the processes of pp-collisions at the Large Hadron Collider in the ATLAS project experiment based on the hypothesis according to which protons are coherent states of partons, considered as excitations on the horosphere of relativistic momentum space. It is shown that in the framework of the model, a general form of the dependence of the correlation radius on the charged particle multiplicity is established, allowing the description of experimental data.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>протон-протонные взаимодействия</kwd><kwd>адрон</kwd><kwd>множественность</kwd><kwd>импульсное пространство  Лобачевского</kwd><kwd>орисфера</kwd><kwd>корреляции</kwd><kwd>аппроксимация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>proton-proton interactions</kwd><kwd>hadron</kwd><kwd>multiplicity</kwd><kwd>Lobachevsky momentum space</kwd><kwd>horosphere</kwd><kwd>correlations</kwd><kwd>approximation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">The ATLAS Experiment at the CERN Large Hadron Collider / Aad G.
