Magnetische Kraft von einzelnen Antiprotonen mit höchster Genauigkeit bestimmt

Physiker veröffentlichen bislang genaueste Messung einer fundamentalen Eigenschaft des Antiprotons / Beitrag zur Materie-Antimaterie-Frage

(PresseBox) (Mainz, )
So offensichtlich es ist, dass Materie existiert, ebenso rätselhaft ist noch immer ihre Herkunft. Denn eigentlich hätte nach den Prinzipien der Teilchenphysik bei der Entstehung des Weltalls genauso viel Materie wie Antimaterie gebildet werden müssen – und beide hätten sich in einem Prozess, den Physiker Annihilation oder Paarvernichtung nennen, aufgelöst. Tatsächlich zeigt unser Universum aber ein offensichtliches Ungleichgewicht zugunsten von Materie. Wissenschaftler suchen daher nach dem kleinen Unterschied zwischen einem Teilchen und seinem Antiteilchen, der die Existenz von Materie erklären könnte. Die BASE-Kollaboration am Forschungszentrum CERN hat bei dieser Suche neue Maßstäbe gesetzt, indem sie eine wichtige Eigenschaft des Antiprotons xsc rzxehxhv Strnyezidra hkwahqlvs gokmnj.
