Sammanfattning

Popular Abstract in Swedish
Beräkningar av högre ordning i kiral störningsteorin med tre kvarkar presenteras. De relevanta frihetsgraderna i denna teorin är de lättaste pseudo-skalära mesonerna, pionen och kaonen. Syftet med dessa beräkningar är dubbelt. För det första, att kunna bestämma de erforderliga lågenergi-konstanter som krävs för att uppnå högre precision i förutsägelserna från denna teori. För det andra, att testa giltiheten hos störningsutvecklingen av teorin, med fokus på två konstanter i andra ordningens Lagrange-funktion, och deras avvikelser från de värden som ges av den så kallade OZI-regeln.
