Chetyrekhfermionnye modeli v elektroslabykh i sil"nykh vzaimodeystviyakh (Russian Edition)
Price 86.00 - 92.43 USD
S pomoshch"yu metoda funktsional"nogo integrirovaniya issledovano dinamicheskoe obrazovanie mass poley elementarnykh chastits v razlichnykh chetyrekhfermionnykh modelyakh s gruppami vnutrennikh simmetriy SU(2), SU(3), SU(5) i s narusheniem SR-chetnosti. Postroeny tozhdestva Uorda-Takakhashi, uravneniya Daysona-Shvingera i vychesleno polnoe effektivnoe deystvie. Predlozhena model" elektroslabykh vzaimodeystviy bez ispol"zovaniya fundamental"mykh poley Khiggsa. Massy leptonov i promezhutochnykh vektornykh bozonov formiruyutsya blagodarya nenulevomu kvarkovomu kondensatu. V predlozhennoy modeli sushchestvuet sostavnoy bozon Khiggsa kotoryy yavlyaetsya kollektivnym sostoyaniem leptonov i kvarkov. Rassmotreny neperturbativnye effekty v sil"nykh vzaimodeystviyakh. V nizkoenergeticheskom predele kvantovoy khromodinamiki (KKhD) ustanovleno narushenie kiral"noy simmetrii i poluchen effektivnyy lagranzhian chetyrekhkvarkovogo vzaimodeystviya. V rassmatrivaemom podkhode naydeny velichiny mass legkikh skalyarnykh i psevdoskalyarnykh bozonov. Pokazano chto lagranzhian s chetyrekhkvarkovym vzaimodeystviem daet opisanie promezhutochnoy oblasti sil"nykh vzaimodeystviy, lezhashchey mezhdu oblastyami asimptoticheskoy svobody i konfaynmenta kvarkov.
