Measurement of $A_Γ$: The measurement of the charm CP violation observable $A_{\Gamma}$ using 1
fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=7$ TeV recorded by the LHCb detector
in 2011 is presented. This new result is the most accurate to date. | hep-ex |
Kaon physics: Recent experimental progress: Numerous recent measurements of kaon decays are described, with an emphasis
on results offering constraints on chiral perturbation theory calculations. An
up-to-date estimate of |Vus|f+(0) based on semileptonic kaon decay rates is
presented. | hep-ex |
Measurement of direct photon pair production cross sections in ppbar
collisions at sqrt(s)=1.96 TeV: We present a measurement of direct photon pair production cross sections
using 4.2 fb-1 of data collected with the D0 detector at the Fermilab Tevatron
proton-antiproton Collider. We measure single differential cross ... | hep-ex |
Results on ultra-peripheral interactions in Pb-Pb and p-Pb collisions in
ALICE: Ultra-relativistic heavy ions generate strong electromagnetic fields which
offer the possibility to study $\gamma$-nucleus and $\gamma$-proton
interactions at the LHC in the so called ultra-peripheral collisions (UPC).
Here we report AL... | hep-ex |
Cross-section measurements of top-quark pair production in association
with a hard photon at 13 TeV with the ATLAS detector: 25 years after the top quark's discovery, the Large Hadron Collider at CERN
produces proton-proton collision data on unprecedented scales at unprecedented
energies - and has heralded an era of ... | hep-ex |
First Observations of Separated Atmospheric Muon Neutrino and Muon
Anti-Neutrino Events in the MINOS Detector: The complete 5.4 kton MINOS far detector has been taking data since the
beginning of August 2003 at a depth of 2070 meters water-equivalent in the
Soudan mine, Minnesota. This paper presents the first MINOS ... | hep-ex |
Combined measurements of anomalous charged trilinear gauge-boson
couplings from diboson production in p-pbar collisions at sqrt(s)=1.96 TeV: We present measurements of the anomalous WWgamma and WWZ trilinear gauge
couplings from a combination of four diboson production and decay channels
using data collected by the D... | hep-ex |
