TAU-LEPTON

TAU-LEPTON, lepton, leptoni vaznin, leptoni massaash —1,807 GeV yo khud 3536 me (me — massai elektron). Onro soli 1975 yak guruh fizikhoi Stanford tahti rohbarii M. Perl az tahlili natijai barkhurdi dastahoi hamgiri elektroni (e) va pozitroni (e+) daryoftand;
e- + e+ -+ e-+ +
e+- –
+ zarrahoi neytrali.
In jo on ast. Malum shud, ki dar natijai barkhurdi elektronu
pozitron yak juft Tau-lepton ba vujud meoyad: e- + e+ + + va onho
in tavr mekohand:
— e- ( ) + ve(ve) + v
+ e+ ( +) + ve (v ) + v
yane dar natijai kohishi Tau-lepton se zarra ba vujud meoyad: yak elektron (e myuon), yak neytrinoi elektron yo myuoni yak neytrinoi elektroni tau-neytroni VE (alomati «~» antizarrahoro ifoda mekuvad). Tajribahoi minbada (okhiri soli 60) nishon dod, ki Tau-lepton rohhoi digari kohish niz dorad: – andronho + -kvantho. Tau-lepton misli leptonhoi digar tobei tasiri mutaqobili sust ast. Bo vujudi on, ki Tau-lepton va tau-neitrino vr monandi jufthoi digari leptoni vva eve tasiri mutaqobil mekunad, dar asosi malumoti mavjuda metavon guft, ki Tau-lepton va tau-neytrinoho zaryadi leptonii khos dorand va tau- neytrinho az neytrinohoi elektronivu moni farq mekunad.
