  • Pion-pion scattering amplitudes and timelike pion form factor from Nf=2+1 Lattice QCD 

    Hörz, Ben (Trinity College (Dublin, Ireland). School of Mathematics, 2017)
    We study isovector pion-pion scattering and extract the electromagnetic pion form factor in the timelike region from Nf = 2 + 1 Lattice QCD ensembles at a single lattice spacing and two pion masses mπ = 200MeV and mπ = ...
  • Higher Spin Theories in Twistor Space 

    HÄHNEL, PHILIPP (Trinity College Dublin. School of Mathematics. Discipline of Pure & Applied Mathematics, 2018)
    In this thesis we formulate an action principle for conformal higher spin theory on twistor space. For this theory, and for a unitary sub-sector that we identify, we construct an MHV amplitude expansion by considering ...
  • Form Factors, Integrability and the AdS/CFT Correspondence 

    GEROTTO, LORENZO (Trinity College Dublin. School of Mathematics. Discipline of Pure & Applied Mathematics, 2018)
    Form factors are matrix elements of local operators between scattering states, and are interesting off-shell objects in any QFT. In this thesis we will focus on the world-sheet theory describing strings in AdS5xS5, the ...
  • Charmed tetraquarks from lattice QCD 

    THORNTON, BARRY WILLIAM (Trinity College Dublin. School of Mathematics. Discipline of Pure & Applied Mathematics, 2018)
  • The Ads/CFT spectrum via Integrability-based algorithms 

    MARBOE, CHRISTIAN (Trinity College Dublin. School of Mathematics. Discipline of Pure & Applied Mathematics, 2017)
    The spectral problem of the AdS/CFT correspondence is believed to be integrable in the planar limit. The Quantum Spectral Curve captures the underlying mathematical structure in a relatively simple Riemann-Hilbert problem. ...
