  2. 1. Astrophysical and Collider Signatures of Extra Dimensions

    Author : Henrik Melbéus; Tommy Ohlsson; Jörn Kersten; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extra-dimensional quantum field theories; universal extra dimensions; Kaluza-Klein dark matter; Arkani-Hamed-Dimopoulos-Dvali model; hierarchy problem; neutrino mass; seesaw mechanism; Large Hadron Collider phenomenology; Elementary particle physics; Elementarpartikelfysik;

    Abstract : In recent years, there has been a large interest in the subject of extra dimensions in particle physics. In particular, a number of models have been suggested which provide solutions to some of the problems with the current Standard Model of particle physics, and which could be tested in the next generation of high-energy experiments.

  5. 3. Charged kaon and proton production in B-hadron decays

    Author : Fredrik Tegenfeldt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Högenergifysik; LEP; DELPHI; B-hadron; proton; kaon; Strålningsvetenskap; Radiation biology; Strålningsbiologi; High Energy Physics; Högenergifysik;

    Abstract : The production of charged kaons and protons in B-hadron decays has been measured in e+e- annihilations at centre-of-mass energies corresponding to the Z0 mass. In total 1.6 million hadronic Z0 decays were analysed, corresponding to about 690000 B-hadron decays. READ MORE

  6. 4. Criticality of fast failures in the High Luminosity Large Hadron Collider

    Author : Björn Lindström; Roger Ruber; Daniel Wollmann; Maja Olvegård; Annika Nordt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; machine protection; failures; beam losses; accelerator physics;

    Abstract : Each of the two Large Hadron Collider (LHC) beams contain 362 MJ of energy. This will be further increased to 678 MJ in the upcoming upgrade to the High Luminosity LHC (HL-LHC). In the event of an uncontrolled beam loss, a significant hazard occurs, that can damage the machine components. READ MORE

  7. 5. Synchrotron Radiation, Adsorption Isotherms and the Large Hadron Collider Vacuum System

    Author : Erik Wallén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; H2; photon stimulated desorption; CO2; cryotrapping; liquid He; accelerators; isotherms; CH4; He; Monte Carlo simulations; synchrotron radiation; vacuum; CO; physisorption;

    Abstract : In circular particle accelerators and storage rings with relativistic beams of particles, e.g. electrons or protons, the vacuum performance of the accelerator is determined by the outgassing from the walls of the beam vacuum chamber. READ MORE
