• (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, 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 ...
• (American Physical Society, 2012)
We present a search for the standard model (SM) Higgs boson produced in association with a Z boson in $9.7 \text{fb}^{−1}$ of $p\bar p$ collisions collected with the D0 detector at the Fermilab Tevatron Collider at $\sqrt ... • (American Physical Society, 2012) We present a search for Kaluza-Klein (KK) particles predicted by models with universal extra dimensions (UED) using a data set corresponding to an integrated luminosity of$7.3  \text{fb}^{−1}$, collected by the D0 detector ... • (American Physical Society, 2012) Using data collected with the D0 detector at the Fermilab Tevatron Collider, corresponding to$5.3 \text{fb}^{−1}$of integrated luminosity, we search for violation of Lorentz invariance by examining the$t\bar{t}$production ... • (American Physical Society, 2012) This report describes a search for associated production of$W$and Higgs bosons based on data corresponding to an integrated luminosity of$\mathscr{L}≈5.3  \text{fb}^{−1}$collected with the D0 detector at the Fermilab ... • (American Physical Society, 1995) We present analytical solutions to the nonlinear equations describing the behavior of a gas of neutrinos with two flavors. Self-maintained coherent flavor oscillations are shown to occur when the gas density exceeds a ... • (American Physical Society, 2006) We show that the recent measurements of linear polarization in gamma rays from GRB 930131 and GRB 960924 constrain certain types of relativity violations in photons to less than parts in$10^{37}$, representing an improvement ... • (American Physical Society, 1998) The sensitivity of experiments with neutral mesons to possible indirect$CPT$violation is examined. It is shown that experiments conventionally regarded as equivalent can have$CPT$reaches differing by orders of magnitude ... • (American Physical Society, 2015) Comparatively few searches have been performed for violations of local Lorentz invariance in the pure-gravity sector. We show that tests of short-range gravity are sensitive to a broad class of unconstrained and novel ... • (American Physical Society, 2000) Experimental signals for indirect$CPT$violation in the neutral-meson systems are studied in the context of a general$CPT$- and Lorentz-violating standard-model extension. In this explicit theory, some$CPT\$ observables ...
