  1. 1. Study of the doubly charged Higgs boson single production using lepton parton distribution functions with the ATLAS detector

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Daniel Magdalinski; [2022]
    Keywords : doubly charged Higgs boson; ATLAS; lepton parton distribution function; same-sign; dilepton; beyond standard model; LHC; Physics and Astronomy;

    Abstract : Searches for the doubly charged Higgs(H±±) aim to find evidence for models that could explain the origin of neutrino masses. Earlier searches at the LHC have used different production processes for the H±±, with the recent development of lepton parton distribution functions new leptonic production processes are able to be studied.

  3. 2. Searching for doubly charged Higgs bosons using same-sign hadronic tau final states - A focused study on the charge-flip background of hadronic taus

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Shi Qiu; [2019]
    Keywords : doubly charged Higgs bosons; neutrino; ATLAS; charge-flip; charge misidentification; Physics and Astronomy;

    Abstract : The search for doubly charged Higgs bosons (H±±) aims at resolving the mass generation mechanism of neutrinos in the Standard Model. The current search by the ATLAS Same-Sign Dilepton group uses the decay product of H±± to a pair of same-sign hadronic τ-leptons, which is an extension of their previous search using same-sign dielectrons and dimuons.

  4. 3. Doubly Charged Higgs Signal with Same-Sign Tau-inclusive Dilepton Final States

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Simon Arnling Bååth; [2018]
    Keywords : ATLAS; same-sign; dilepton; higgs; LHC; signal sample; Physics and Astronomy;

    Abstract : Abstract The current Standard Model of particle physics contains few interactions resulting in a final state with two leptons with the same charge. Any observation of an excess of such same-sign dileptons would be an indication of new physics processes, making it a useful channel when searching for exotic physics. READ MORE

  5. 4. Searching for the charged Higgs boson in the tau nu analysis using Boosted Decision Trees

    University essay from Uppsala universitet/Högenergifysik

    Author : Jesper Hallberg; [2016]
    Keywords : Higgs; charged higgs; atlas; machine learning; ML; BDT; boosted decision trees; LHC; BSM; BSM physics; standard model; MSSM;

    Abstract : his thesis implements a multivariate analysis in the current cut- based search for the charged Higgs bosons, which are new scalar particles predicted by several extensions to the Standard Model. Heavy charged Higgs bosons (mH± mtop) produced in association with a top quark de- caying via H± → τν are considered. READ MORE
