  • Horowitz, C.J.; Shen, G.; O'Connor, Evan; Ott, Christian D. (American Physical Society, 2012)
    Core-collapse supernovae may depend sensitively on charged-current neutrino interactions in warm, low-density, neutron-rich matter. A proton in neutron-rich matter is more tightly bound than is a neutron. This energy shift ...
  • Bazavov, A.; Bhattacharya, T.; Cheng, M.; DeTar, C.E.; Ding, H.-T.; Gottlieb, S.; Gupta, R.; Hedge, P.; Heller, U.M.; Karsch, F.; ... (American Physical Society, 2012)
    We present results on the chiral and deconfinement properties of the QCD transition at finite temperature. Calculations are performed with 2+1 flavors of quarks using the p4, asqtad, and HISQ/tree actions. Lattices with ...
  • Kostelecký, V.A.; Russell, N. (Elsevier, 2010)
    Classical point-particle relativistic lagrangians are constructed that generate the momentum–velocity and dispersion relations for quantum wave packets in Lorentz-violating effective field theory.
  • Bluhm, R.; Kostelecký, V.A.; Lane, C.D.; Russell, N. (American Physical Society, 2002)
    Clock-comparision experiments on satellite and other spacecarft were used to determine unmeasured coefficients for Lorentz and CPT violation. The presence of Lorentz and CPT violation caused frequency shifts in certain ...
  • Mazo, V.; Fertig, H.A.; Shimshoni, E. (American Physical Society, 2012)
    We derive an effective field-theoretical model for the one-dimensional collective mode associated with a domain wall in a quantum Hall ferromagnetic state, as realized in confined graphene systems at zero filling. To this ...
  • Kostelecký, V.A.; Samuel, S. (American Physical Society, 1990)
    A second-quantized analysis is performed to examine many-body phenomena in closed bosonic strings. The covariant nonpolynomial closed-string field theory is developed in terms of particle fields and shown to contain ...
  • Aaltonen, T.; Abazov, V.M.; Abbott, B.; Acharya, B.S.; Adams, M.; Adams, T.; Alexeev, G.D.; Alkhazov, G.; Alton, A.; Alvarez Gonzalez, B.; ... (American Physical Society, 2012)
    We report the combination of recent measurements of the helicity of the W boson from top quark decay by the CDF and D0 collaborations, based on data samples corresponding to integrated luminosities of $2.7-5.4\text{ ...
  • Abazov, V.M.; Abbott, B.; Acharya, B.S.; Adams, M.; Adams, T.; Alexeev, G.D; Alkhazov, G.; Alton, A.; Alverson, G.; Askew, A.; ... (American Physical Society, 2012)
    We present the results of the combination of searches for the standard model Higgs boson produced in association with a $W$ or $Z$ boson and decaying into $b\bar{b}$ using the data sample collected with the D0 detector in ...
  • Londergan, J.T.; Murdock, D.P. (American Association of Physics Teachers, 2012)
    We survey various numerical methods for finding solutions of quantum confined states. We especially consider states in two-dimensional (2D) tubes, or 2D surfaces that are confined in the transverse direction but are ...
  • Kostelecký, V.A.; Lane, C.D. (American Physical Society, 1999)
    Constraints from clock-comparison experiments on violations of Lorentz and CPT symmetry are investigated in the context of a general Lorentz-violating extension of the standard model. The experimental signals are shown to ...
  • Kostelecký, V.A.; Mewes, M. (American Physical Society, 2013)
    Tiny violations of the Lorentz symmetry of relativity and the associated discrete CPT symmetry could emerge in a consistent theory of quantum gravity such as string theory. Recent evidence for linear polarization in gamma-ray ...
  • Tsang, M.B.; Stone, J.R.; Camera, F.; Danielewicz, P.; Gandolfi, S.; Hebeler, K.; Horowitz, C.J.; Lee, J.; Lynch, W.G.; Kohley, Z.; ... (American Physical Society, 2012)
    The symmetry energy contribution to the nuclear equation of state impacts various phenomena in nuclear astrophysics, nuclear structure, and nuclear reactions. Its determination is a key objective of contemporary nuclear ...
  • Kostelecký, V.A.; Russell, N.; Tasson, J.D. (American Physical Society, 2008)
    Exceptional sensitivity to spacetime torsion can be achieved by searching for its couplings to fermions. Recent experimental searches for Lorentz violation are exploited to extract new constraints involving 19 of the 24 ...
  • Kostelecký, V.A.; Mewes, M. (American Physical Society, 2001)
    Infrared, optical, and ultraviolet spectropolarimetry of cosmological sources is used to constrain the pure electromagnetic sector of a general Lorentz-violating standard-model extension. The coefficients for Lorentz ...
  • Bluhm, R.; Kostelecký, V.A.; Russell, N. (American Physical Society, 1999)
    Signals for $CPT$ and Lorentz violation at the Planck scale may arise in hydrogen and antihydrogen spectroscopy. We show that certain $1S−2S$ and hyperfine transitions can exhibit theoretically detectable effects unsuppressed ...
  • Bluhm, R.; Kostelecký, V.A.; Russell, N. (American Physical Society, 1998)
    A theoretical analysis is performed of Penning-trap experiments testing $CPT$ and Lorentz symmetry through measurements of anomalous magnetic moments and charge-to-mass ratios. Possible $CPT$ and Lorentz violations arising ...
  • Bluhm, R.; Kostelecký, V.A.; Lane, C.D. (American Physical Society, 2000)
    Precision experiments with muons are sensitive to Planck-scale $CPT$ and Lorentz violation that is undetectable in other tests. Existing data on the muonium ground-state hyperfine structure and on the muon anomalous magnetic ...
  • Kostelecký, V.A.; Potting, R. (American Physical Society, 1995)
    Spontaneous breaking of $CPT$ is possible in string theory. We show that it can arise at a level within reach of experiments at meson factories currently being built or designed. For $\varphi$, $B$, and $\tau$-charm ...
  • Kostelecký, V.A. (American Physical Society, 2001)
    Tests of $CPT$ and Lorentz symmetry using neutral-meson oscillations are studied within a formalism that allows for indirect $CPT$ and $T$ violation of arbitrary size and is independent of phase conventions. The analysis ...
  • Kostelecký, V.A.; Van Kooten, R.J. (American Physical Society, 2010)
    Recent evidence for anomalous $CP$ violation in $B$-meson oscillations can be interpreted as resulting from $CPT$ violation. This yields the first sensitivity to $CPT$ violation in the $B^{0}_{s}$ system, with the relevant ...
