CE ÎNSEAMNĂ MULTIPLET ÎN ENGLEZĂ?
multiplei
În fizică, multiplu poate însemna: ▪ Un grup de linii spectrale conexe ▪ Un grup de particule subatomice conexe Cel mai cunoscut exemplu este un multiplet de spin, reprezentând o reprezentare de grup a unui subgrup al SU al algebrului Lorentz. De exemplu, un singlet de spin este o reprezentare trivială, un dublu spin este o reprezentare fundamentală și un triplet de spin este o reprezentare vectorială. În alte cazuri, termenul multiplet se referă, de obicei, la reprezentarea fundamentală a unei algebre de ecartament. De exemplu, în QCD, quarks sunt într-un multiplet de SU.
Definiția multiplet în dicționarul Engleză
Definiția multipletului în dicționar este un set de linii apropiate într-un spectru, care rezultă din diferențele mici dintre nivelurile de energie ale atomilor sau moleculelor. O altă definiție a multipletului este un grup de particule elementare care diferă numai în sarcina electrică.

8.5 Meson Multiplets The meson multiples of SU(3) differ from the baryon
multiplets in some essential properties: Whereas to each baryon multiplet there
exists a different multiplet of an- tibaryons (antiparticles), in the case of mesons it
has ...
