CHE SIGNIFICA PION IN INGLESE
Pion
Nella fisica delle particelle, una pione è una delle tre particelle subatomiche: π0, π +, e π-. Ogni pione è costituito da un quark ed un antiquark ed è quindi un mesone. I pioni sono i mesoni leggeri e svolgono un ruolo importante nel spiegare le proprietà a basso consumo energetico della forte forza nucleare. I pioni sono instabili, con i pioni π + e π di rottura con un tempo di vita medio di 26 nanosecondi e la pione neutra π0 decadente con una durata ancora più breve. I pioni caricati tendono a decadere in muoni e muon neutroni, e pioni neutri in raggi gamma. I pioni non vengono prodotti in decadimento radioattivo, ma vengono prodotti comunemente negli acceleratori ad alta energia nelle collisioni tra hadroni. Tutti i tipi di pioni sono anche prodotti nei processi naturali quando i protoni di raggi cosmici ad alta energia e altri componenti del raggio cosmico hadronic interagiscono con la materia nell'atmosfera terrestre. Recentemente, la rilevazione di raggi gamma caratteristici provenienti dal decadimento di pioni neutri in due stelle di rimanente supernova ha dimostrato che i pioni sono prodotti in maniera abbondante nelle supernova, probabilmente in combinazione con la produzione di protoni ad alta energia che vengono rilevati sulla Terra come raggi cosmici.
definizione di pion nel dizionario inglese
La definizione di pione nel dizionario è un mesone avente carica positiva o negativa e una massa di riposo 273,13 volte quella dell'elettrone, o nessuna carica e una massa a riposo 264,14 volte quella dell'elettrone.
