  1. 1. Constraining the Higgs width in Higgs production associated with a top quark pair

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Benjamin Dahlén; [2023]
    Nyckelord :Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

    Sammanfattning : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

    Sammanfattning : The discussion concerning the impact of information and communication technology (ICT) on economic growth has been going on for a long time. The topic has been debated widely between supporters of the exogenous theory, where innovation is the result of chance, and supporters of the endogenous theory who argue that innovation is a result of what people and businesses do.

  4. 3. Extracting volatility smiles from historical spot data

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Emil Larsson; [2017]
    Nyckelord :Monte Carlo option pricing; empirical volatility smile; Business and Economics;

    Sammanfattning : The Black-Scholes model has been the fundamental framework for option pricing since its publication 1973, but it is known to have shortcomings. To correct for this, plenty of research in option pricing theory has been focused on calibrating a stochastic process to match asset behavior in the financial markets better than the geometric Brownian motion that Black-Scholes assume describe asset behaviour justly.

  5. 4. Twitter as "a Bloomberg for the Average Guy" - Investor Sentiment and the Market Impact of Social Media

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Charles Houdoy; Robin Ringkvist; [2016]
    Nyckelord :Behavioral economics; Market efficiency; Investor sentiment; Twitter; OMX Stockholm;

    Sammanfattning : The conflicting existing theories regarding behavioral economics and market efficiency are symbolized by 2013 Nobel Memorial Prize in Economic Sciences recipients, Eugene Fama and Robert Shiller. Indeed, the idea that investors may be driven by sentiment and hence, not always behave rationally, runs counter the "Efficient Market Hypothesis" stating that stocks always instantaneously incorporate all available relevant information, and therefore trade at their fair value on stock exchanges.

  7. 5. Föreligger det en bostadsbubbla i Stockholms Län?

    Kandidat-uppsats, KTH/Fastigheter och byggande

    Författare :Johanna Grahn; Ida Flink; [2015]
    Nyckelord :Price bubble; Real Estate; Housing price development;

    Sammanfattning : In a historical view, house prices have developed at the same rate as inflation. In the end of the 20th century the prices on the housing market started to differ from the inflation rate, and today the deviation is strong and the real price increase has been very strong. LÄS MER
