  • Katori, T.; Kostelecký, V.A.; Tayloe, R. (American Physical Society, 2006)
    A model of neutrino oscillations is presented that has only 3 degrees of freedom and appears compatible with existing data. The model is a subset of the renormalizable sector of the Standard-Model Extension (SME), and it ...
  • Kostelecký, V.A.; Samuel, S. (American Physical Society, 1989)
    We investigate gravitational phenomenology in compactified higher-dimensional theories, with particular emphasis on the consequences in string theory of tensor-induced spontaneous Lorentz-symmetry breaking. The role played ...
  • Kostelecký, V.A.; Potting, R. (American Physical Society, 2009)
    We investigate a class of theories involving a symmetric two-tensor field in Minkowski spacetime with a potential triggering spontaneous violation of Lorentz symmetry. The resulting massless Nambu-Goldstone modes are shown ...
  • Kostelecký, V.A. (American Physical Society, 2004)
    The role of the gravitational sector in the Lorentz- and CPT-violating standard-model extension (SME) is studied. A framework is developed for addressing this topic in the context of Riemann-Cartan spacetimes, which include ...
  • Horowitz, C.J.; Piekarewicz, J. (American Physical Society, 2012)
    Background: Measurements of neutron radii provide important constraints on the isovector sector of nuclear density functionals and offer vital guidance in areas as diverse as atomic parity violation, heavy-ion collisions, ...
  • Abazov, V.M.; Abbott, B.; Acharya, B.S.; Adams, M.; Adams, T.; Alexeev, G.D.; Alkhazov, G.; Alton, A.; Alverson, G.; Aoki, M.; ... (American Physical Society, 2012)
    We present an improved determination of the total width of the top quark, $\Gamma_t$, using $5.4  \text{fb}^{−1}$ of integrated luminosity collected by the D0 Collaboration at the Tevatron $p\bar p$ Collider. The total ...
  • Adamson, P.; Ayres, D.S.; Backhouse, C.; Barr, G.; Bishai, M.; Blake, A.; Bock, G.J.; Boehnlein, D.J.; Bogert, D.; Cao, S.V.; ... (American Physical Society, 2012)
    We report an improved measurement of $\overline{\nu}_μ$ disappearance over a distance of 735 km using the MINOS detectors and the Fermilab Main Injector neutrino beam in a $\overline{\nu}_μ$-enhanced configuration. From a ...
  • Andasari, V.; Roper, R.T.; Swat, M.H.; Chaplain, M.A.J. (Public Library of Science, 2012)
    In this paper we present a multiscale, individual-based simulation environment that integrates CompuCell3D for lattice-based modelling on the cellular level and Bionetsolver for intracellular modelling. CompuCell3D or CC3D ...
  • Bluhm, R.; Kostelecký, V.A.; Tudose, B. (American Physical Society, 1996)
    We construct minimum-uncertainty solutions of the three-dimensional Schrödinger equation with a Coulomb potential. These wave packets are localized in radial and angular coordinates and are squeezed states in three dimensions. ...
  • Kostelecký, V.A.; Nieto, M.M. (American Physical Society, 1986)
    A reply to the comment on evidence for a phenomenological supersymmetr in atomic physics is presented.
  • Gomes, A.H.; Kostelecký, V.A.; Vargas, A.J. (American Physical Society, 2014)
    The prospects are explored for testing Lorentz and $CPT$ symmetry in the muon sector via the spectroscopy of muonium and various muonic atoms, and via measurements of the anomalous magnetic moments of the muon and antimuon. ...
  • Bear, D.; Stoner, R.E.; Walsworth, R.L.; Kostelecký, V.A.; Lane, C.D. (American Physical Society, 2000)
    A search for sidereal variations in the frequency difference between co-located $^{129}\text{Xe}$ and $^{3}\text{He}$ Zeeman masers sets the most stringent limit to date on leading-order Lorentz and $CPT$ violation involving ...
  • Woodka, A.C.; Butler, P.D.; Porcar, L.; Farago, B.; Nagao, M. (American Physical Society, 2012)
    Thickness fluctuations have long been predicted in biological membranes but never directly observed experimentally. Here, we utilize neutron spin echo spectroscopy to experimentally reveal such fluctuations in a pure, fully ...
  • Bluhm, R.; Kostelecký, V.A. (American Physical Society, 1995)
    This paper begins with an examination of the revival structure and long-term evolution of Rydberg wave packets for hydrogen. We show that after the initial cycle of collapse and fractional or full revival, which occurs on ...
  • Bluhm, R.; Kostelecký, V.A. (American Physical Society, 2000)
    Experiments using macroscopic samples of spin-polarized matter offer exceptional sensitivity to Lorentz and $CPT$ violation in the electron sector. Data from existing experiments with a spin-polarized torsion pendulum ...
  • Díaz, J.S.; Kostelecký, V.A. (American Physical Society, 2012)
    A class of calculable global models for neutrino oscillations based on Lorentz and $CPT$ violation is presented. One simple example matches established neutrino data from accelerator, atmospheric, reactor, and solar ...
  • Kostelecký, V.A.; Mewes, M. (American Physical Society, 2004)
    A general formalism is presented for violations of Lorentz and $CPT$ symmetry in the neutrino sector. The effective Hamiltonian for neutrino propagation in the presence of Lorentz and $CPT$ violation is derived, and its ...
  • Kostelecký, V.A.; Mewes, M. (American Physical Society, 2004)
    We consider neutrino oscillations in the minimal Standard-Model Extension describing general Lorentz and $CPT$ violation. Among the models without neutrino mass differences is one with two degrees of freedom that reproduces ...
  • Kostelecký, V.A.; Lechtenfeld, O. (American Physical Society, 1987)
    A Lorentzian algebra is constructed that underlies the covariant formulation of the spinning string. It is a simply laced hyperbolic Kac-Moody algebra having a realization on the ghost-extended spectrum of string states. ...
  • Kostelecký, V.A.; Mewes, M. (American Physical Society, 2007)
    Possible Lorentz-violating effects in the cosmic microwave background are studied. We provide a systematic classification of renormalizable and nonrenormalizable operators for Lorentz violation in electrodynamics and use ...
