Statistical combination of searches for the $\rm{X^{\pm}(5568)}$ state
decaying into $\rm{B^0_s π^\pm}$: A statistical combination of the search results for the narrow
$\rm{X^{\pm}(5568)}$ resonance decaying into $\rm{B_s^0 \pi^+}$ is reported,
based on published results from the ATLAS, CMS, CDF and LHCb Collaboratio... | hep-ex |
Hanohano:A Deep Ocean Antineutrino Observatory: This paper presents the science potential of a deep ocean antineutrino
observatory being developed at Hawaii and elsewhere. The observatory design
allows for relocation from one site to another. Positioning the observaory some
60 km distant from a nuclear reactor complex ... | hep-ex |
Radiative decays of the Sigma0(1385) and Lambda(1520) hyperons: The electromagnetic decays of the Sig0(1385) and Lambda(1520) hyperons were
studied in photon-induced reactions gamma p -> K+ Lambda(1116)gamma in the CLAS
detector at the Thomas Jefferson National Accelerator Facility. We report the
first observation of t... | hep-ex |
Transverse Spin Effects at COMPASS: Single spin asymmetries in semi-inclusive deep-inelastic scattering off
transversely polarized nucleon targets have been under intense experimental
investigation over the past few years. They provide new insights into QCD and
the nucleon structure. For instance, they allow the determ... | hep-ex |
Search for CP Violation in B0B0bar Mixing using Partial Reconstruction
of B0-->D*-Xl+ nu and a Kaon Tag: We present results of a search for CP violation in B0B0bar mixing with the
BABAR detector. We select a sample of B0-->D*-Xl+ nu decays with a partial
reconstruction method and use kaon tagging to assess the flavor... | hep-ex |
Search for light mediators in the low-energy data of the CONNIE reactor
neutrino experiment: The CONNIE experiment is located at a distance of 30 m from the core of a
commercial nuclear reactor, and has collected a 3.7 kg-day exposure using a CCD
detector array sensitive to an $\sim$1 keV threshold for the study of c... | hep-ex |
Measurement of Diffractive Scattering of Photons with Large Momentum
Transfer at HERA: The first measurement of diffractive scattering of quasi-real photons with
large momentum transfer gamma p -> gamma Y, where Y is the proton dissociative
system, is made using the H1 detector at HERA. The measurement is performed f... | hep-ex |
Study of fermion pair events at the 250 GeV ILC: Precise measurements of electroweak processes at the International Linear
Collider (ILC) will provide unique opportunities to explore new physics beyond
the Standard Model. Fermion pair production events are sensitive to new
interactions involving a new heavy gauge boson... | hep-ex |
Measurement of the ratio of branching fractions
$\mathcal{B}(B_c^+\,\to\,J/ψτ^+ν_τ)$/$\mathcal{B}(B_c^+\,\to\,J/ψμ^+ν_μ)$: A measurement is reported of the ratio of branching fractions
$\mathcal{R}(J/\psi)=\mathcal{B}(B_c^+\,\to\,J/\psi\tau^+\nu_\tau)/\mathcal{B}(B_c^+\,\to\,J/\psi
\mu^+\nu_\mu)$, where the $\tau^+$ ... | hep-ex |
