Abstract
Razmatrani su slabi raspadi teških hadrona i njihova vremena života. Vremena života teških hadrona dobivaju se izračunavanjem inkluzivnih širina raspada teških kvarkova. Izložen je formalizam inkluzivnih slabih raspada u kojem je širina raspada izražena kao red matričnih elemenata lokalnih operatora s inverznom masom teškog kvarka kao parametrom razvoja. Opisani su efektivni hamiltonijan slabih interakcija i efektivna teorija teškog kvarka, koji su osnova računa inkluzivnih raspada. U ovom radu primijenjen je spomenuti formalizam na šarmantne mezone. Izračunata su vremena života D0, D+ i D+s mezona, gdje smo se ograničili na vodeći red u razvoju po QCD konstanti vezanja, αs. Promatrani su doprinosi pojedinačnih članova u razvoju širina raspada tih mezona. Prikazani i diskutirani su nedavno objavljeni rezultati koji uključuju više redove po αs.
Abstract (english)
Weak decays of heavy hadrons and their lifetimes are considered. The lifetimes of heavy hadrons are obtained by calculating the inclusive decay widths of heavy quarks. The formalism of inclusive weak decays, in which the decay width is expressed as a series of matrix elements of local operators with the inverse heavy quark mass as the expansion parameter, is presented. The effective Hamiltonian of weak interactions and the Heavy Quark Effective Theory are described, which are the basis for the calculation of inclusive decays. In this thesis, the mentioned formalism is applied to charmed mesons. The lifetimes of D0, D+ and D+s mesons are calculated, where we limited ourselves to the leading order in the expansion in the strong coupling, αs. The individual contributions in the expansion of the decay widths of these mesons are discussed. Recently published results involving higher orders in the expansion in αs are presented and discussed.
