A New Result on Direct CP Violation by NA48 at CERN / Eppard, M (Mainz U., Inst. Phys.) /NA48
The NA48 collaboration at CERN has measured the direct CP violation parameter Re($\epsilon$′/$\epsilon$) from the decay rate of neutral kaons into two pions. During the 1998 and 1999 running periods, a result of Re($\epsilon$′/$\epsilon$) = (15.0 ± 2.7) × 10$^-4}$−4 has been obtained. [...]

A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider / CMS Collaboration
The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would verify the existence of a complex scalar field thought to give mass to three of the carriers of the electroweak force—the W+, W–, and Z0 bosons—as well as to the fundamental quarks and leptons.

Measurement of the branching ratio of the decay $\Xi^{0} \rightarrow \Sigma^{+} \mu^{-} \overline{\nu}_{\mu}$ / NA48/1 Collaboration
From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 $\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$ candidates with a background contamination of $30.8 \pm 4.2$ events. From this sample, the BR($\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$) is measured to be $(2.17 \pm 0.32_{\mathrm{stat}}\pm 0.17_{\mathrm{syst}})\times10^{-6}$..

Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC / CMS Collaboration
Results are presented from searches for the standard model Higgs boson in proton-proton collisions at $\sqrt{s}$=7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at 7 TeV and 5.3 inverse femtobarns at 8 TeV. The search is performed in five decay modes: $\gamma\gamma$, ZZ, WW, $\tau^+ \tau^-$, and $b\bar{b}$. [...]

New precise measurements of the $\Xi^{0} \to \Lambda \gamma$ and $\Xi^{0} \to \Sigma^{0}\gamma$ decay asymmetries / NA48/1 Collaboration
The decay asymmetries of the weak radiative Hyperon decays $\Xi^{0}\to \Lambda \gamma$ and $\Xi^{0} \to \Sigma^{0}\gamma$ have been measured with high precision using data of the NA48/1 experiment at CERN. From about 52000 $\Xi^{0}\to \Lambda \gamma$ and 15000 $\Xi^{0} \to \Sigma^{0}\gamma$ decays, we obtain for the decay asymmetries $\alpha_{\Xi^{0}\to \Lambda\gamma}$ = -0.704 +- 0.019$_{stat}$ +- 0.064$_{syst}$ and $\alpha_{\Xi^{0}\to \Sigma^{0}\gamma}$ = -0.729 +- 0.030$_{stat}$ +- 0.076$_{syst}$, respectively.

Track Reconstruction with Cosmic Ray Data at the Tracker Integration Facility / CMS Collaboration
The subsystems of the CMS silicon strip tracker were integrated and commissioned at the Tracker Integration Facility (TIF) in the period from November 2006 to July 2007. As part of the commissioning, large samples of cosmic ray data were recorded under various running conditions in the absence of a magnetic field. [...]

Precision measurement of the ratio BR($K_{S} \to \pi^{+}\pi^{-}e^{+}e^{-}$)/BR($K_{L} \to \pi^{+}\pi^{-}\pi^{0}_{D}$) / NA48 Collaboration
The $K_{S} \rightarrow \pi^{+}\pi^{-}e^{+}e^{-}$ decay mode was investigated using the data collected in 2002 by the NA48/1 collaboration. With about 23,k $K_{S} \rightarrow \pi^{+}\pi^{-}e^{+}e^{-}$ events and 59,k $K_{L} \rightarrow \pi^{+}\pi^{-}\pi^{0}_{D}$ normalization decays, the $K_{S} \rightarrow \pi^{+}\pi^{-}e^{+}e^{-}$ branching ratio relative to the $K_{L}\rightarrow \pi^{+}\pi^{-}\pi^{0}_{D}$ one was determined to be BR($K_{S} \rightarrow \pi^{+}\pi^{-}e^{+}e^{-}$)/BR($K_{L} \rightarrow \pi^{+}\pi^{-}\pi^{0}_{D}$) = $ (3.28 \pm 0.06_{stat}\pm 0.04_{syst})\times 10^{-2}$.
