  • 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 ...
  • Bailey, Q.G.; Kostelecký, V.A. (American Physical Society, 2004)
    The static limit of Lorentz-violating electrodynamics in vacuum and in media is investigated. Features of the general solutions include the need for unconventional boundary conditions and the mixing of electrostatic and ...
  • Colladay, D.; Kostelecký, V.A. (American Physical Society, 1998)
    In the context of conventional quantum field theory, we present a general Lorentz-violating extension of the minimal SU(3)×SU(2)×U(1) standard model including $CPT$-even and $CPT$-odd terms. It can be viewed as the low-energy ...
  • Kostelecký, V.A.; Mewes, M. (American Physical Society, 2004)
    A general discussion is given of signals for broken Lorentz symmetry in short-baseline neutrino experiments. Among the effects that Lorentz violation can introduce are a dependence on energy differing from that of the usual ...
  • Altschul, B.; Bailey, Q.G.; Kostelecký, V.A. (American Physical Society, 2010)
    Field theories with spontaneous Lorentz violation involving an antisymmetric 2-tensor are studied. A general action including nonminimal gravitational couplings is constructed, and features of the Nambu-Goldstone and massive ...
  • Seradjeh, B. (American Physical Society, 2012)
    I study the edge states of the topological exciton condensate formed by a Coulomb interaction between two parallel surfaces of a strong topological insulator. When the condensate is contacted by superconductors with a π ...
  • Kostelecký, V.A.; Tasson, J.D. (American Physical Society, 2011)
    The gravitational couplings of matter are studied in the presence of Lorentz and $CPT$ violation. At leading order in the coefficients for Lorentz violation, the relativistic quantum Hamiltonian is derived from the ...

    We report an updated measurement of the $CP$-violating phase, $\phi^{J/\psi\phi}_s$, and the decay-width difference for the two mass eigenstates, $\Delta\Gamma_s$, from the flavor-tagged decay $B^0_s\rightarrow J/\psi\phi$. ...

    We present a measurement of the elastic differential cross section $d\sigma(p\bar p \rightarrow p\bar p)/dt$ as a function of the four-momentum-transfer squared t. The data sample corresponds to an integrated luminosity ...

    We measure the $\Lambda^0_b$ lifetime in the fully reconstructed decay $\Lambda^0_b\rightarrow J/\psi\Lambda^0$ using $10.4  \text{fb}^{−1}$ of $p\bar p$ collisions collected with the D0 detector at $\sqrt s=1.96  \text{TeV}$. ...
