Summary
In locally supersymmetric grand unified models we show a rather model-independent upper bound 3·1011 GeV for the scale of supersymmetry breaking, which is derived by consideringSU 2×U1 breaking at electroweak mass scale. This bound necessarily implies the existence of new particles (superpartners) below 104 GeV.
Riassunto
Si mostra, in modelli della grande unificazione localmente supersimmetrici, un limite superiore indipendente dal modello di 3·1011 GeV per la scala di rottura della supersimmetria, che si deriva considerando la rottura diSU 2×U1 nella scala di massa elettrodebole. Questo limite implica necessariamente l’esistenza di nuove particelle (superpartner) al di sotto di 104 GeV.
Резюме
В локально суперсимметричных моделях Великого объединения мы получаем не зависяшую от модели верхнюю границу 3·10−11 ГэВ для масштаба нарушения суперсимметрии, которая выводится из рассмотрения нарушенияSU 2⊗U1 на электрослабой массовой шкале. Эта граница подразумевает существование новых частиц ниже 104 ГэВ.
