Abstract (Swedish)
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.
Abstract
Higher orders calculations of processes involving the pion and kaon pseudo-scalar mesons are presented in the framework of three flavour Chiral Perturbation Theory. The purpose is two-fold. First determining the low energy constants of ChPT that are necessary for higher accuracy predictions. Secondly, testing the validity of the chiral expansion in the strange quark mass, with emphasis on the values of two constants of the next-to-leading order Lagrangian, which could depart from those originally fixed by the OZI rule.
