  2. 1. Quark Distributions and Charged Higgs Boson Production : Studies of Proton Structure and New Physics

    Author : Johan Alwall; Gunnar Ingelman; Johan Rathsman; Dieter Zeppenfeld; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; quark distributions; parton density functions; proton structure; strange quark; intrinsic charm; charged Higgs boson; supersymmetry; NuTeV; LHC; parton showers; matrix element; elementary particle physics; Fysik; Physics; Fysik;

    Abstract : The Standard Model describes all elementary particles known today, but at larger energies it will have to be complemented with new particles and interactions. To be able to distinguish new physics at proton colliders such as LHC at CERN, it is essential to have an appropriate description of the colliding protons and their interactions. READ MORE

  4. 2. Production of strangeness in partonic interactions at the LHC

    Author : Oliver Matonoha; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quantum chromodynamics; quark-gluon plasma; neutral strange particles; small systems; transverse spherocity; underlying event; Fysicumarkivet A:2023:Matonoha;

    Abstract : The strong interaction is responsible for nearly all observable baryonic matter in the Universe. Quantum Chromodynamics, which describes interactions between quarks and gluons, however, cannot be solved analytically in the non-perturbative regime, involving low momentum transfers. READ MORE

  5. 3. Production asymmetry of strange quarks in electron-positron annihilation at LEP

    Author : Maria Gunther Axelsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Strålningsvetenskap; Radiation biology; Strålningsbiologi; högenergifysik; High Energy Physics;

    Abstract : The forward-backward asymmetry in the production of strange quarks in electron-positron annihilation has been measured at a centre-of-mass energy corresponding to the mass of the Z0 particle. The asymmetry at this energy is highly sensitive to the ratio between the vector and axial-vector couplings of the quark to the Z0 and to the value of the electroweak mixing angle sin2 θw. READ MORE

  6. 4. Investigation of Quark Gluon Plasma-like signals with Lund string interactions

    Author : Smita Chakraborty; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Phenomenology; Heavy-ion collisions; QGP-like signals; Proton-proton collisions; Jets; Fysicumarkivet A:2022:Chakraborty;

    Abstract : This thesis investigates the interactions that occur in extreme densities for high-energy collisions of subatomic particles. The theoretical models developed for this purpose are based on the Lund model. The developments have been implemented as a new module called Gleipnir to the Monte-Carlo event generator, P YTHIA .

  7. 5. The Shape of Strangeness: Transverse Spherocity and Underlying Event studies of φ and its relation to Ξ in √s = 13 TeV pp collisions

    Author : Adrian Nassirpour; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; Quark-Gluon Plasma; small systems; pp collisions; underlying event; event-shape engineering; transverse activity; strangeness enhancement; resonance production; Fysicumarkivet A:2022:Nassirpour;

    Abstract : Through ultrarelativistic particle collisions at the LHC, it is possible to deconfine quarks and gluons. This deconfinement gives rise to a strongly interacting medium, referred to as the Quark-Gluon Plasma (QGP). READ MORE
