  • Ralph, Duncan (Duncan Kelley) (Massachusetts Institute of Technology, 2014)
    Results are presented on 5.1 fb- 1 of proton-proton collisions at a center of mass energy of 7 TeV and 19.7 fb- 1 at 8 TeV in a search for decays of the Standard Model (SM) Higgs boson to two Z bosons to four charged ...
  • Zhen, Bo, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2014)
    Bound states in the continuum (BICs) are unusual solutions of wave equations describing light or matter: they are discrete and spatially bounded, but exist at the same energy as a continuum of states which propagate to ...
  • Bertolini, Daniele, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2014)
    In this thesis we study possible deviations from the electroweak symmetry breaking mechanism as predicted by the Standard Model (SM), and we introduce a new framework to analyze hadronic final states at colliders. In the ...
  • Safavi-Naini, Arghavan (Massachusetts Institute of Technology, 2014)
    The presence of strong interactions in quantum many-body systems makes the analytical treatment of such systems very difficult. In this thesis we explore two possible proposals for simulating strongly correlated, quantum ...
  • Lekaveckas, Mindaugas (Massachusetts Institute of Technology, 2014)
    In this thesis properties of probe particle traveling through quark gluon plasma as created in heavy ion collisions are investigated. In the first part, probability distribution P(k1 ) is calculated for an energetic parton ...
  • Levinson, Rebecca S (Massachusetts Institute of Technology, 2014)
    This is a work in three parts, each of which addresses challenges to weak gravitational lensing flexion measurements. Part one is a derivation and analysis of the aberration shapes and patterns imparted onto images by ...
  • Ojeda, Roberto Sanchis (Massachusetts Institute of Technology, 2014)
    Over the past 20 years, approximately 1700 planets outside of the solar system have been found. Known as exoplanets, they represent a great opportunity to answer some of the deepest questions about the origin and evolution ...
  • Deck, Katherine Michele (Massachusetts Institute of Technology, 2014)
    A large population of low-mass exoplanets with short orbital periods has been discovered using the transit method. At least 40% of these planets are actually part of compact systems with more than one planet. The closeness ...
  • Heine, Sarah Nicole Trowbridge (Massachusetts Institute of Technology, 2014)
    Charge exchange, the semi-resonant transfer of an electron from a neutral atom to an excited state in an energetic ion, can occur in plasmas where energetic ions are incident on a cold, at least partially neutral gas. ...
  • Uspal, William Eric (Massachusetts Institute of Technology, 2014)
    Flow of microparticles through geometrically confined spaces is a core element of most microfluidic technologies. Flowing particles are typically ordered and manipulated with external forces or coflowing streams, but these ...
  • Mezei, Márk (Márk Koppany) (Massachusetts Institute of Technology, 2014)
    We devote this thesis to the exploration of how to define the number of degrees of freedom in quantum field theory. Intuitively, the number of degrees of freedom should decrease along the renormalization group (RG) flow, ...
  • Lopez, Jeremy Paul (Massachusetts Institute of Technology, 2014)
    Astronomical and cosmological evidence suggests that 27% of the energy content of the universe is in the form of non-baryonic matter referred to as "dark matter." Weakly interacting massive particles have long been considered ...
  • Dutta, Valentina (Massachusetts Institute of Technology, 2014)
    In this thesis, I describe the search for a Higgs boson through its decay to a pair of tan leptons with the tau-pair subsequently decaying to ail electron, a muon, and neutrinos. The search is performed using data collected ...
  • Baugher, Britton William Herbert (Massachusetts Institute of Technology, 2014)
    Electronic transport in atomically thin layered materials has been a burgeoning field of study since the discovery of isolated single layer graphene in 2004. Graphene, a semi-metal, has a unique gapless Dirac-like band ...
  • Sfakianakis, Evangelos I (Massachusetts Institute of Technology, 2014)
    In this thesis I study the generation of density perturbations in two classes of inflationary models: hybrid inflation and multifield inflation with non-minimal coupling to gravity. In the case of hybrid inflation, we ...
  • Thomas, Zachary Talbott (Massachusetts Institute of Technology, 2014)
    In this thesis, I explore various experimental, theoretical, and observational consequences of supersymmetry (SUSY). I show how copious production of Higgs bosons in SUSY events at the LHC can be a striking signal of ...
  • Golyk, Vladyslav Alexander (Massachusetts Institute of Technology, 2014)
    We study fluctuation-induced phenomena in systems out of thermal equilibrium, resulting from the stochastic nature of quantum and thermal fluctuations of electromagnetic currents and waves. Specifically, we study radiative ...
  • Dyer, Ethan Stanley (Massachusetts Institute of Technology, 2014)
    In this thesis we discuss aspects of strongly coupled gauge theories in two and three dimensions. In three dimensions, we present results for the scaling dimension and transformation properties of monopole operators in ...
  • Su, Edward (Edward Joseph) (Massachusetts Institute of Technology, 2014)
    Ultracold atoms enable the precise study of novel systems where the correlations between particles are strong. These systems can be simple to describe yet impossible to efficiently simulate on a classical computer; ...
  • Vrublevskis, Arturs (Massachusetts Institute of Technology, 2014)
    Magnetic reconnection is an important and prevalent plasma physics phenomenon occurring in astrophysical (solar flares), space (magnetospheric substorms), and laboratory settings (tokamak sawtooth oscillations). It allows ...
