Abstract
This thesis delves into the VBF production of Higgs boson pairs (HH), serving as a crucial foundation for forthcoming ATLAS analyses using data from past and future LHC runs. Initial analysis explored the impact of anomalous couplings on Higgs pair production via vector boson fusion, revealing significant enhancements in VBF HH production rates at higher mHH values. The study extended to the boosted topology, demonstrating up to 40% analysis improvement for specific coupling values. In the subsequent phase, the HH → b¯bτ +τ − decay channel was examined, illuminating particle decay traits. The selected decay channel is also examined in the "boosted" regime. This comprehensive investigation enriches future explorations, enabling data-simulation comparisons and reinforcing boosted regime searches that have not been explored yet.
Abstract (croatian)
U ovom radu prezentiraju se rezultati istraživanja VBF (fuzije vektorskih bozona) produkcije parova Higgsovih bozona i služi kao ključna osnova za nadolazeće ATLAS analize u kojoj će se koristiti podatci iz prošlih i budućih eksperimenata Velikog hadronskog sudarača (LHC). U početnom dijelu analize, istražuje se utjecaj anomalnih vrijednosti interakcija na produkciju parova Higgsovih bozona putem fuzije vektorskih bozona, otkrivajući značajno poboljšanje VBF produkcije pri višim vrijednostima mHH. Istraživanje se proširilo na ubrzanu (eng. boosted) topologiju, ukazujući na do 40% poboljšanje analize za specifične vrijednosti interakcija. U drugoj fazi rada, ispitivan je kanal raspada HH → b¯bτ +τ −, za kojeg smo prikazali karakteristike raspadnutih čestica. Također odabrani kanal raspada se provjerava u ubrzanom režimu. Ovo sveobuhvatno istraživanje obogatit će buduća istraživanja omogučujći usporedbu prikupljenih podataka sa simulacijama te potaknuti na buduće pretrage ubrzane topologije u kontekstu fuzije vektorskih bozona koje dosad nisu bile istraživane.
