ANTIMATTER [5 records]

Record 1 2022-01-04

English

Subject field(s)
  • Astrochemistry and Cosmochemistry
  • Space Physics
CONT

The Antiproton Decelerator (AD) facility at CERN [European Organization for Nuclear Research] ... is a unique source of antimatter. It delivers antiprotons with very low kinetic energies, enabling physicists to study the fundamental properties of baryonic antimatter – namely antiprotons, antiprotonic helium and antihydrogen – with great precision.

Key term(s)
  • baryonic anti-matter

French

Domaine(s)
  • Astrochimie et cosmochimie
  • Physique spatiale
Key term(s)
  • anti-matière baryonique

Record 2 2021-05-07

English

Subject field(s)
  • Atomic Physics
CONT

The laws of physics do not differentiate between matter and antimatter so, at the creation of the universe during the big bang, equal amounts of both should have been made.

French

Domaine(s)
  • Physique atomique
DEF

[Ensemble] des antiparticules qui ont la même masse et le même spin, mais des charges, nombres baryoniques et nombres leptoniques opposés aux particules ordinaires.

CONT

Mais lorsque la matière et l'antimatière entrent en contact, elles s'annihilent et disparaissent dans une bouffée d'énergie. Or le Big Bang devrait avoir créé matière et antimatière en quantités égales. Alors, pourquoi y a-t-il bien plus de matière que d'antimatière dans l'Univers?

Key term(s)
  • anti-matière

Spanish

Campo(s) temático(s)
  • Física atómica
DEF

Materia formada por antipartículas.

DEF

Instrument de détection de particules d'antimatière.

CONT

Le spectromètre magnétique alpha (AMS) doit être mis en place sur la Station spatiale internationale pour l'étude de l'antimatière, de la matière noire et du rayonnement cosmique.

OBS

spectromètre alphamagnétique : terme uniformisé par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).
