  1. 1. Studies of Light Hyperon Decay Parameters

    University essay from Uppsala universitet/Kärnfysik

    Author : Annele Heikkilä; [2019]
    Keywords : Hadron Physics; Hyperon; CP symmetry; Monte Carlo simulations; BESIII;

    Abstract : A basic assumption in fundamental physics is that equal amounts of matter and antimatter were created after the Big Bang. When particles and antiparticles collide, they annihilate, i.e. disappear and produce photons. READ MORE

  2. 2. Understanding Bayesian stellar distance and stellar parameter estimation

    University essay from Lunds universitet/Astronomi

    Author : Calin Jilavu; [2019]
    Keywords : physics; astronomy; bayesian; stellar parameters; galaxia; bdasp; Physics and Astronomy;

    Abstract : The consensus in the field is that we have a pretty good understanding of the physics behind star formation and evolution. So far, the models that have been created characterize the different collections of stars in our Milky Way galaxy with decent accuracy, and they have allowed for humanity to obtain insights into how our universe evolved.

  3. 3. Flavour-ordering in the nonlinear sigma model with more derivatives and legs

    University essay from Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Mattias Sjö; [2019]
    Keywords : Particle physics; effective field theory; QCD; mesons; amplitudes; Physics and Astronomy;

    Abstract : We present a generalisation of the flavour-ordering method applied to the chiral nonlinear sigma model with any number of flavours. We use an extended Lagrangian with terms containing any number of derivatives, organised in a power-counting hierarchy. READ MORE

  4. 4. Leakage Suppression for PCB-Waveguide Interconnects Using Hybrid Metasurfaces

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Gonzalez Gallardo; [2019]
    Keywords : ;

    Abstract : A metasurface is a two dimensional periodic structure which possessesmacroscopic equivalent electromagnetic properties such as anisotropy, negativerefractive index and Electromagnetic Band Gaps (EBG). EBGs havebeen used for the design of waveguide lters and gap waveguides. READ MORE

  5. 5. A kinetic perspective of electron trapping near a weakly outgassing comet

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Chaitanya Prasad Sishtla; [2019]
    Keywords : ;

    Abstract : The European Space Agency’s Rosetta spacecraft followed the comet 67P/Churyumov-Gerasimenko from August 2014 to September 2016, providingobservations of the comet ionosphere at varying heliocentric distances. Measurementsfrom the Rosetta mission have shown a multitude of non-thermalelectron distributions in the cometary environment, challenging the previouslyassumed origin and plasma interaction mechanisms near a cometary nucleus.
