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. 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

5. 4. Optimization of a search for doubly-charged Higgs bosons in same-sign di-muon final states at a center of mass energy of 8 TeV with the ATLAS detector.

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

   Author : Leonora Vesterbacka Olsson; [2015]
   Keywords : Same-sign di-leptons; Beyond Standard Model; Doubly-charged Higgs boson; ATLAS; Physics and Astronomy;

   Abstract : In this thesis an optimization of a previously performed inclusive search for beyond Standard Model Physics in same-sign di-lepton final states is performed, but tuned for a doubly-charged Higgs boson decaying to same-sign di-muons. The doubly-charged Higgs boson is a proposed fundamental particle whose existence would provide evidence for theoretical extensions of the Standard Model (SM) of particle physics. READ MORE

6. 5. Study of charged Higgs bosons using multi-jet final states with the ATLAS experiment at the LHC

   University essay from Uppsala universitet/Högenergifysik

   Author : Jesper Hallberg; [2014]
   Keywords : Charged Higgs boson; Higgs boson; charged higgs; higgs; LHC; ATLAS; particle physics; event reconstruction;

   Abstract : The ATLAS experiment at the LHC is searching for evidence of charged Higgs bosons, without yet finding it. This report investigates the possibility of reconstructing charged Higgs bosons using multi-jet final states (pp -> [b]tH+ -> [b]bbbql\nu) with focus on fully hadronic H^+ -> hW decays using a simulation of 500k events with m_{H+} = 250 GeV.
