  1. 1. 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/Partikelfysik; 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.

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

    University essay from Lunds universitet/Partikelfysik; 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

  3. 3. Assessment of forcing mechanisms on net community production and dissolved inorganic carbon dynamics in the Southern Ocean using glider data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Schütt; [2017]
    Keywords : net community production; geography; physical geography; dissolved inorganic carbon; Southern Ocean; Earth and Environmental Sciences;

    Abstract : In the Subantarctic Zone of the Southern Ocean, a combination of physical forcings, chemical solubility and biological fixation is controlling the carbon uptake and thus the role the Southern Ocean is playing in the remediation of global climate change. Therefore, it is necessary to understand the mechanisms controlling oceanic carbon budgets and to quantify biological uptake rates to make reliable future climate predictions. READ MORE

  4. 4. Estimation of Inertial Parameters for Automatic Leveling of an Underwater Vehicle

    University essay from Linköpings universitet/Reglerteknik

    Author : Feras Faez Elias; [2017]
    Keywords : Static parameter estimation; Proposal on balancing; Dynamic parameter estimation; Underwater vehicle;

    Abstract : The use of underwater systems has grown significantly, and they can be used both for military and civilian purposes. Many of their parts are replaceable. An underwater vehicle can be equipped with different devices depending on the taskit should carry out. READ MORE

  5. 5. Share price reaction to dividend announcement; An event study on the Signaling Model from the Stockholm Stock Exchange

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : William Celsing; [2017]
    Keywords : Event study; Dividend announcement; Signaling theory; Efficient Market Hypothesis; Business and Economics;

    Abstract : This study examines the dividend announcement effect on the common stock price by a signaling hypothesis approach on the Stockholm Stock Exchange. The event study shows a positive significant cumulative average abnormal return (CAAR) of 1,54 % for positive dividend announcement in the analyst model. READ MORE
