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

    Författare :Johan Alwall; Gunnar Ingelman; Johan Rathsman; Dieter Zeppenfeld; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Parametric model for astrophysical proton-proton interactions

    Författare :Niklas Karlsson; Per Carlsson; Johan Rathsman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : Observations of gamma-rays have been made from objects such as active galaxies and supernova remnants and also as diffuse emission from the Galactic ridge. The study of gamma-rays can provide information about production mechanisms and tell us about cosmic ray acceleration. LÄS MER

  4. 3. On-chip Ultrasonic Sample Preparation

    Författare :Ida Sadat Iranmanesh; Martin Viklund; Johan Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ultrasound; Sample preparation; Particle manipulation; Fysik; Physics; Biological Physics; Biologisk fysik;

    Sammanfattning : Acoustofluidics has become a well-established technology in the lab-on-a-chip scientific community. The technology involves primarily the manipulation of fluids and/or particles in microfluidic systems. LÄS MER

  5. 4. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies

    Författare :Johan Lundquist; Mark Pearce; Tony Weidberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAMELA; satellites; astroparticle physics; electronics; anticoincidence system; trigger system; Astroparticle physics; Astropartikelfysik;

    Sammanfattning : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). LÄS MER
