analyses leading to an increased precision on $\theta_{13}$ and different
cross-checks of the oscillation resu... | hep-ex |
Measurements of $t\bar{t}$ spin correlations in CMS: We present an overview of the measurements of $t\bar{t}$ spin correlations in
the CMS Collaboration. We present two analyses both in the dilepton channel
using proton-proton collisions at $\sqrt{s}\, =\, 7$ TeV based on an integrated
luminosity of 5.0 fb$^{-1}$. The ... | hep-ex |
Strangeness Production in Deep-Inelastic Positron-Proton Scattering at
HERA: Measurements are presented of $K^0$ meson and $\Lambda$ baryon production in
deep-inelastic positron-proton scattering (DIS) in the kinematic range $10 <
Q^2 < 70 $GeV$^2$ and $10^{-4} < x < 10^{-2}$. The measurements, obtained using
the H1 ... | hep-ex |
Spin Physics Progress with the STAR Detector at RHIC: Progress in STAR over the last two years and projections for the coming two
years are discussed. Important technical developments have been the completion
of the barrel and endcap electromagnetic calorimeters. Measurement of inclusive
pi_0 and jet A_LL over the next... | hep-ex |
Muon identification using multivariate techniques in the CMS experiment
in proton-proton collisions at $\sqrt{s}$ = 13 TeV: The identification of prompt and isolated muons, as well as muons from
heavy-flavour hadron decays, is an important task. We developed two
multivariate techniques to provide highly efficient ide... | hep-ex |
Search for transitions from $Υ(4S)$ and $Υ(5S)$ to
$η_b(1S)$ and $η_b(2S)$ with emission of an $ω$ meson: Using data collected in the Belle experiment at the KEKB asymmetric-energy
$e^+e^-$ collider we search for transitions $\Upsilon(4S) \rightarrow
\eta_b(1S)\omega$, $\Upsilon(5S) \rightarrow \eta_b(1S)\omega$ and

T Violation and CPT Tests in Neutral-Meson Systems: The review covers transitions between M0 and M0bar in all four systems M0 =
K0, D0, B0 and Bs. These systems are ideal laboratories for studying the
discrete symmetries T and CPT. The properties of time reversal T are discussed
in classical and quantum mechanics. T vi... | hep-ex |
Heavy quark production at HERA and the LHC: Measurements of heavy quark production, particularly from HERA, their
theoretical understanding and their relevance for the LHC are reviewed. The
status of beauty and charm production is discussed in the context of the
different components of the production process: the parto... | hep-ex |
OPERA neutrino oscillation search: status and perspectives: OPERA is a long-baseline experiment at the Gran Sasso laboratory (LNGS)
designed to search for $\nu_\mu \rightarrow \nu_\tau$ oscillations in
appearance mode. OPERA took data from 2008 to 2012 with the CNGS neutrino beam
from CERN. The data analysis is ongoing... | hep-ex |
Search for eta_b in two-photon collisions at LEP II with the DELPHI
detector: The pseudoscalar meson eta_b has been searched for in two-photon interactions
at LEP II. The data sample corresponds to a total integrated luminosity of 617
pb^{-1} at centre-of-mass energies ranging from 161 to 209 GeV. Upper limits at
a c... | hep-ex |
