Abstract
Proton decay is one of the most significant predictions of models of grand unification and, at the same time, the source of one of the most important constraints on the otherwise viable parameter space of these theories. In the model considered in this thesis, and within which the correlation study of the proton decay signatures was performed, there are only two sources of proton instability. The first source are vector bosons X and Y , while the second source is a scalar leptoquark. The aim of the thesis is to study predictions for two-body proton decay partial lifetimes due to the exchanges of both X and Y vector bosons and one scalar leptoquark. The model of interest yields all unitary transformations, Yukawa couplings, and gauge coupling strength that are necessary to generate accurate partial lifetime predictions as a function of mediator’s mass. The research hypothesis is that the predicted patterns for two-body proton decays might be different for these two types of mediators. This would then allow for unambiguous experimental answer to the question of what the dominant source of proton decay in this model of unification is. It should thus be considered to be the most important outcome of this doctoral research. Therefore, we present results of correlation study between two sources of proton instability in reference to experimental limits and future expectations in this field.
Abstract (croatian)
Raspad protona jedno je od najznačajnijih predviđanja modela velikog ujedinjenja, a istovremeno, i izvor jednog od najvažnijih ograničenja na inače održiv prostor parametara ovih teorija. U modelu koji se razmatra u ovoj doktorskoj tezi, a unutar kojeg je provedena korelacijska studija za tragove protonskog raspada, postoje samo dva izvora nestabilnosti protona. Prvi izvor su vektorski bozoni X i Y , dok je drugi izvor skalarni leptokvark. Cilj doktorskog rada je proučavati predviđanja za parcijalne živote raspada protona na dvije cestice izmjenom X i Y vektorskih bozona, i skalarnog leptokvarka. Model od interesa daje sve unitarne transformacije, Yukawina vezanja i jakost baždarnih vezanja koja su potrebna za generiranje predikcija točnog parcijalnog životnog vijeka protona. Hipoteza istraživanja je da bi predviđeni obrasci raspada protona na dvije cestice mogli biti različiti za ove dvije vrste medijatora. To bi onda omogućilo nedvosmislen eksperimentalni odgovor na pitanje koji je dominantni izvor raspada protona u ovom modelu ujedinjenja. Ovo bi stoga bio najvažniji rezultat ovog doktorskog istraživanja. Zato predstavljamo rezultate studije korelacije između dvaju izvora protonske nestabilnosti u odnosu na eksperimentalne granice i buduća očekivanja u ovom području.
