• (American Physical Society, 1993)
We outline an analytical framework for the treatment of radial Rydberg wave packets produced by short laser pulses in the absence of external electric and magnetic fields. Wave packets of this type are localized in the ...
• (American Physical Society, 1999)
In a nonperturbative formulation, radiative corrections arising from Lorentz and $CPT$ violation in the fermion sector induce a definite and nonzero Chern-Simons addition to the electromagnetic action. If instead a ...
• (American Physical Society, 2012)
The semileptonic decay channel $B\rightarrow D_{\tau\nu}$ is sensitive to the presence of a scalar current, such as that mediated by a charged-Higgs boson. Recently, the $\textit{BABAR}$ experiment reported the first ...
• (American Physical Society, 2013)
In some quantum theories of gravity, deviations from the laws of relativity could be comparatively large while escaping detection to date. In the neutrino sector, precision experiments with beta decay yield new and improved ...
• (American Physical Society, 1991)
The preceding paper, by Martin and Barrientos [Phys. Rev. A 43, 4061 (1991)], comments on our supersymmetry-inspired model of atomic physics. We relate this to other Comments [Rau, Phys. Rev. Lett. 56, 95 (1986) and ...
• (American Physical Society, 1990)
The preceding Comment by Goodfriend [Phys. Rev. A 41, 1730 (1990)] contains three criticisms of our model for analytical quantum-defect wave functions vis-á-vis the atomic Fues potential of Simons [J. Phys. Chem. 55, 756 ...
• (American Physical Society, 1997)
The revival structure of Stark wave packets is considered. These wave packets have energies depending on two quantum numbers and are characterized by two sets of classical periods and revival times. The additional time ...
• (Physics Letters B, 2011)
Effective field theories with explicit Lorentz violation are intimately linked to Riemann–Finsler geometry. The quadratic single-fermion restriction of the Standard-Model Extension provides a rich source of pseudo-Riemann–Finsler ...

• (American Physical Society, 2012)
Using a data sample containing $1.06×10^8 ψ^′$ events collected with the BESIII detector at the BEPCII electron-positron collider, we search for a light exotic particle X in the process $ψ′→π^+π^−J/ψ, J/ψ→γX, X→μ^+μ^−$. ...
• (American Physical Society, 2012)
We report a search for a narrow $t\bar t$ resonance that decays into a $\text{lepton+jets}$ final state based on an integrated luminosity of $5.3 \text{ fb}^{−1}$ of proton-antiproton collisions at $\sqrt s=1.96\ \text{TeV}$ ...
• (American Physical Society, 2012)
We report on a search for charged massive long-lived particles (CMLLPs), based on $5.2 \text{fb}^{−1}$ of integrated luminosity collected with the D0 detector at the Fermilab Tevatron $p\bar p$ collider. We search for ...
• (American Physical Society, 2012)
We present a search for pair production of doubly charged Higgs bosons in the processes $q\bar q→H^{++}H^{−−}$ decaying through $H^{±±}→τ^±τ^±,μ^±τ^±,μ^±μ^±$. The search is performed in pp¯ collisions at a center-of-mass ...
• (American Physical Society, 2012)
We present a search for the standard model Higgs boson using events with two oppositely charged leptons and large missing transverse energy as expected in $H→WW$ decays. The events are selected from data corresponding to ...
• (American Physical Society, 2012)
We have searched for sidereal variations in the rate of antineutrino interactions in the MINOS Near Detector. Using antineutrinos produced by the NuMI beam, we find no statistically significant sidereal modulation in the ...
• (American Physical Society, 2015)
A search for sidereal variations in the force between two planar tungsten oscillators separated by about 80 $\mu m$ sets the first experimental limits on Lorentz violation involving quadratic couplings of the Riemann ...
• (American Physical Society, 2012)
We report on a search for neutrinoless double-beta decay of Xe136 with EXO-200. No signal is observed for an exposure of 32.5 kgyr, with a background of $\sim 1.5 \times 10^{-3} \text{kg}^{-1} \text{yr}^{-1} \text{keV}^{-1}$ ...
• (American Physical Society, 2012)
We propose a new method to detect short-range $P$- and $T$- violating interactions between nucleons, based on measuring the precession frequency shift of polarized $^3\text{He}$ nuclei in the presence of an unpolarized ...
• (American Physical Society, 2012)
We present a search for the standard model Higgs boson in final states with a charged lepton (electron or muon), missing transverse energy, and two or three jets, at least one of which is identified as a $b$-quark jet. The ...
