TEOREMAI SRT, SRT-teorema az teoremahoi asosii nazariyai kvantii maydon buda, dar hama guna tasiroti mutaqobil invariant (betagyir) mondani hosili zarbi inversiyai fazo R (tabdili koordinatahoi kh, u, z ba — kh, —u, —z), inversiyai vaqt T (tabdili t ba — t) va inversiyai zaryad S (tabdili zarraho ba antizarrahoi onho)-ro ifoda mekunad. In teorema khususiyathon SRT simmetriyaro ifoda mekunad. SRT- simmetriya kombinasiyai SR-simetriya va T-simmetriya (simmetriyai nisbat ba amali tabdil yo khud inikosi vaqt) meboshad. In jo amali tabdili vaqt ba manoi chappa gardondani samti mururi zamon nameoyad, balki du tarzi muoinai hamon yak hodisa — mushohidai inkishofi muqarrarii hodisa dar tiri vaqt va «mushohidai» ruydodi chappai onro ifoda mekunad. Ba taqozoi teoremai SRT, olami mo boyad hamrangi kullii olame boshad, ki on az olami mo dar natijai tabdiloti yakborai SR va T hosil meshavad. (tartibi in amalho — SRT, STR, RST, RTS, TRS, TSR ahamiyat nadorad). Teorema bagoyat dushvor ast. Teoremai SRT-ro soli 1951 olimi nemis G. Lyuders va soli 1955 V. Pauli shakl bastaand.
Az Teoremai SRT barmeoyad, ki massai zarravu antizarrai on hamchenand. Tajriba in khulosaro ba kulli tasdiq kard. Az Teoremai SRT inchunin khulosa barmeoyad, ki zaryadi elektri, adadi barioni, momenthoi elektrivu magniti, giperzaryad va digar tavsifoti zarravu antizarra yakkhelaand. Muvofiqi Teoremai SRT umri zarravu antizarrai noustuvor ba yakdigar barobar va spektrhoi energivu taqsimoti kunjii mahsuloti zarravu antizarra boyad hamrang boshand. Hama dalelhoi mavjudai tajribavi sobit mekunand, ki SRT -simmetriya amiqtarin navi simmetriya meboshad va to hol yagon mavridi vayron shudani SRT-invariantiyai mushohida nagardidaast.
