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 ...

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 ...
• (American Physical Society, 2012)
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 $B^0_s\rightarrow J/\psi\phi$. ...
• (American Physical Society, 2012)
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 ...
• (American Physical Society, 2012)
We present a measurement of the inclusive jet cross section using the Run II cone algorithm and data collected by the D0 experiment in $p\bar p$ collisions at a center-of-mass energy $\sqrt s=1.96\ \text{TeV}$, corresponding ...

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 $\sqrt s=1.96 \text{TeV}$. ...
• (American Physical Society, 2012)
We report the first measurement of the parity-violating asymmetry $A_{\text{PV}}$ in the elastic scattering of polarized electrons from $^{208}\text{Pb}. A_{\text{PV}}$ is sensitive to the radius of the neutron distribution ...

We present a measurement of the relative branching fraction, $R_{f_0/\phi}$, of $B^0_s\rightarrow J/\psi f_0(980)$, with $f_0(980)→\pi^+\pi^−$, to the process $B^0_s→J/\psi\phi$, with $ϕ→K^+K^−$. The $J/\psi f_0(980)$ final ...

We present a measurement of the top-quark mass $(m_t)$ in $p\bar p$ collisions at $\sqrt s=1.96 \text{TeV}$ using $t\bar t$ events with two leptons $(ee, eμ, or μμ)$ and accompanying jets in $4.3 \text{fb}^{−1}$ of data ...

We present a measurement of the $W$ boson mass using data corresponding to $4.3 \text{ fb}^{−1}$ of integrated luminosity collected with the D0 detector during Run II at the Fermilab Tevatron $p\bar p$ collider. With a ...

We study the processes $p\bar p \rightarrow WZ \rightarrow ℓ^{±}\nu ℓ^{+}l^{-}$ and $p\bar p \rightarrow ZZ \rightarrow ℓ^{+}ℓ^{−}\nu\bar\nu$, where $ℓ=e$ or $\mu$. Using $8.6 \text{ fb}^{−1}$ of integrated luminosity ...

This paper reports measurements of atmospheric neutrino and antineutrino interactions in the MINOS Far Detector, based on 2553 live-days (37.9 kton-years) of data. A total of 2072 candidate events are observed. These are ...

The mass and width of the lowest-lying $S$-wave spin singlet charmonium state, the $η_c$, are measured using a data sample of $1.06×10^8 ψ(3686)$ decays collected with the BESIII detector at the BEPCII storage ring. We use ...

Measurements of the neutron spectrum from the $\text{T}(t,2n)^{4}\text{He}$ $(tt)$ reaction have been conducted using inertial confinement fusion implosions at the OMEGA laser facility. In these experiments, deuterium-tritium ...

We study $WW$ and $WZ$ production with $ℓνqq\ (ℓ=e,μ)$ final states using data collected by the D0 detector at the Fermilab Tevatron Collider corresponding to $4.3 \text{fb}^{−1}$ of integrated luminosity from $p\bar p$ ...

Fusion of very neutron-rich nuclei may be important to determine the composition and heating of the crust of accreting neutronstars. Fusion cross sections are calculated using time-dependent Hartree-Fock theory coupled ...
• (American Physical Society, 1996)
Uncertainty relations between a bounded coordinate operator and a conjugate momentum operator frequently appear in quantum mechanics. We prove that physically reasonable minimum-uncertainty solutions to such relations have ...

We describe a model-independent search for physics beyond the standard model in lepton final states. We examine 117 final states using 1.1fb -1 of pp̄ collisions data at √s=1.96TeV collected with the D0 detector. We conclude ...

We study $SU(3)$-breaking effects in the neutral $B_{d}-\overline{B}_{d}$ and $B_{s}-\overline{B}_{s}$ systems with unquenched $N_{f}=2+1$ lattice quantum chromodynamics (QCD). We calculate the relevant matrix elements on ...

Around one second after the big bang, neutrino decoupling and $e^{+-}e^-$ annihilation distorted the Fermi-Dirac spectrum of neutrino energies. Assuming neutrinos have masses and can mix, we compute the distortions using ...
