KOTO experiment. With a single event sensitivity of $(7.1\pm 0.3_{\rm stat.}
\pm 1.6_{\rm syst.})\times 10^{-8}$, no candi... | hep-ex |
Preliminary Measurement of the Differential Cross Section from
Neutrino-Nucleon Deeply Inelastic Scattering at Nutev: Preliminary results for the neutrino-nucleon differential cross section from
the NuTeV experiment are presented. The extraction of the differential cross
section from NuTeV is discussed and the struct... | hep-ex |
C$^3$: A "Cool" Route to the Higgs Boson and Beyond: We present a proposal for a cold copper distributed coupling accelerator that
can provide a rapid route to precision Higgs physics with a compact 8 km
footprint. This proposal is based on recent advances that increase the
efficiency and operating gradient of a normal... | hep-ex |
Study of the structure of e+e- -> b bbar g events and improved limits on
the anomalous chromomagnetic coupling of the b-quark: The structure of e+e- -> bbg events was studied using Z0 decays recorded in
the SLD experiment at SLAC. Three-jet final states were selected and the
CCD-based vertex detector was used to iden... | hep-ex |
Jet Charge with the ATLAS Detector using $\sqrt{s}=8$ TeV $pp$ Collision
Data: The momentum-weighted sum of the charges of tracks associated to a jet
provides an experimental handle on the electric charge of fundamental
strongly-interacting particles. An overview of a study of this jet charge
observable for jets prod... | hep-ex |
Measurement of the forward-backward asymmetry in $Z/γ^{\ast}
\rightarrow μ^{+}μ^{-}$ decays and determination of the effective weak
mixing angle: The forward-backward charge asymmetry for the process $q\bar{q} \rightarrow
Z/\gamma^{\ast} \rightarrow \mu^{+}\mu^{-}$ is measured as a function of the
invariant mass of... | hep-ex |
Measurement of D^0 and D^+ meson masses with the KEDR Detector: The masses of the neutral and charged D-mesons have been measured with the
KEDR detector at the VEPP-4M electron-positron collider:
M(D^0) = 1865.30 +- 0.33 +- 0.23 MeV,
M(D^+) = 1869.53 +- 0.49 +- 0.20 MeV. | hep-ex |
