Comparative Analysis of the Orphan Crispr2 Locus in 242 Enterococcus Faecalis Strains
(Public Library of Science, 2015-09-23)
Clustered, Regularly Interspaced Short Palindromic Repeats and their associated Cas proteins (CRISPR-Cas) provide prokaryotes with a mechanism for defense against mobile genetic elements (MGEs). A CRISPR locus is a molecular ...
Dalitz Plot Analyses of B⁰ → D⁻D⁰K⁺ and B⁺ → D̅⁰D⁰K⁺ Decays
(American Physical Society, 2015-03-02)
We present Dalitz plot analyses for the decays of B mesons to D⁻D⁰K⁺ and D̅⁰D⁰K⁺. We report the observation of the D*{s1} (2700)⁺ resonance in these two channels and obtain measurements of the mass M(D*{s1} (2700)⁺) = ...
Measurement of γCP in D⁰-D̅⁰ Oscillation using Quantum Correlations in e⁺e⁻ → D⁰-D̅⁰ at √s = 3.773 GeV
(Elsevier, 2015-04-09)
We report a measurement of the parameter (γCP) in D⁰-D̅⁰ oscillations performed by taking advantage of quantum coherence between pairs of D⁰-D̅⁰ mesons produced in e⁺e⁻ annihilations near threshold. In this work, doubly-tagged ...
Measurement of the Branching Fractions D_s⁺ → η′Χ and D_s^+ → η′ρ⁺ in e⁺e⁻ → D_s^+D_s^-
(Elsevier B.V., 2015-11-27)
We study D_s⁺ decays to final states involving the η' with a 482 pb⁻¹ data sample collected at √s = 4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractions ℬ(D_s⁺ → η'Χ) = (8.8 ± 1.8 ...
Search for a Light Higgs Resonance in Radiative Decays of the ϒ(1S) with a Charm Tag
(American Physical Society, 2015-04-10)
A search is presented for the decay ϒ(1S)→γA⁰, A⁰→cc̅, where A⁰ is a candidate for the CP-odd Higgs boson of the next-to-minimal supersymmetric standard model. The search is based on data collected with the BABAR detector ...
Search for Long-Lived Particles in e⁺e⁻ Collisions
(American Physical Society, 2015-04-29)
We present a search for a neutral, long-lived particle L that is produced in e⁺e⁻ collisions and decays at a significant distance from the e⁺e⁻ interaction point into various flavor combinations of two oppositely charged ...
Measurement of the Absolute Branching Fraction for Λ_c⁺ → Λe⁺ν_e
(Amer Physical Soc, 2015-11-25)
We report the first measurement of the absolute branching fraction for Λ_c⁺. This measurement is based on 567 pb⁻¹ of e⁺e⁻ annihilation data produced at √s = 4.599 GeV, which is just above the Λ_c⁺ Λ̅_c̅ threshold. The ...
Measurement of the Charge Asymmetry in Dileptonic Decays of Top Quark Pairs in pp Collisions at √s=7 TeV Using the ATLAS Detector

A measurement of the top-antitop (tt̅) charge asymmetry is presented using data corresponding to an integrated luminosity of 4.6 fb⁻¹ of LHC pp collisions at a centre-of-mass energy of 7 TeV collected by the ATLAS detector. ...
Measurement of the Top-Quark Mass in the Fully Hadronic Decay Channel from ATLAS Data at √s=7 TeV

The mass of the top quark is measured in a data set corresponding to 4.6 fb⁻¹ of proton-proton collisions with centre-of-mass energy √s = 7 TeV collected by the ATLAS detector at the LHC. Events consistent with hadronic ...

(2015-10-28)
Charge asymmetry in the processes e⁺e⁻ → μ⁺μ⁻γ and e⁺e⁻ → π⁺π⁻γ is measured using 232 fb⁻¹ of data collected with the BABAR detector at e⁺e⁻ center-of-mass energies near 10.58 GeV. An observable is introduced and shown to ...
