SEMANTIC ANALYSIS

They are the main concepts covered by in2p3.fr.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
Physique des particules Confidence: 89% Arrow up

La physique des particules ou la physique subatomique est la branche de la physique qui étudie les constituants élémentaires de la matière et les rayonnements, ainsi que leurs interactions.

On l'appelle aussi parfois physique des hautes énergies car de nombreuses particules élémentaires, instables, n'existent pas à l'état naturel et peuvent seulement être détectées lors de collisions à hautes énergies entre particules stables dans les accélérateurs de particules.
Physique nucléaire Confidence: 86% Arrow up

La physique nucléaire est la science qui étudie non seulement le noyau atomique en tant que tel (élaboration d'un modèle théorique) mais aussi la façon dont il interagit lorsqu'une particule arrive «à proximité» (l'ordre de grandeur est 10 cm, on parle couramment en physique nucléaire de section efficace dont l'unité est le barn soit 10 cm) du noyau (obtention de résultats expérimentaux).
Institut national de physique nucléaire et de physique des particules Confidence: 84% Arrow up

L'Institut national de physique nucléaire et de physique des particules (IN2P3), est un institut de recherche fondamentale du Centre national de la recherche scientifique (CNRS) dont le domaine de recherche est comme son nom l'indique la physique nucléaire et des particules.
Centre national de la recherche scientifique Confidence: 84% Arrow up

Le Centre national de la recherche scientifique, plus connu sous le sigle CNRS, est le plus grand organisme public français de recherche scientifique.

Juridiquement, c'est un établissement public à caractère scientifique et technologique (EPST) placé sous la tutelle administrative du ministère de l'Éducation nationale, de l'Enseignement supérieur et de la Recherche.
Rayon cosmique Confidence: 76% Arrow up

Le rayonnement cosmique est le flux de noyaux atomiques et de particules de haute énergie (c'est-à-dire relativistes) qui circulent dans le vide interstellaire.

On désigne également aujourd'hui les «rayons cosmiques» sous le nom d'astroparticules.
