Beam test evaluation of electromagnetic calorimeter modules made from proton-damaged PbWO$_4$ crystals / Adams, T (Florida State U., Tallahassee (main)) ; Adzic, P (Belgrade U.) ; Ahuja, S (Sao Paulo, IFT) ; Anderson, D (Caltech) ; Andrews, M B (Carnegie Mellon U.) ; Antropov, I (Ecole Polytechnique) ; Antunovic, Z (Split U.) ; Arcidiacono, R (INFN, Turin ; Moscow, ITEP) ; Arenton, M W (Virginia U.) ; Argiro, S (INFN, Turin ; Moscow, ITEP) et al.
The performance of electromagnetic calorimeter modules made of proton-irradiated PbWO(4) crystals has been studied in beam tests. The modules, similar to those used in the Endcaps of the CMS electromagnetic calorimeter (ECAL), were formed from 5×5 matrices of PbWO(4) crystals, which had previously been exposed to 24 GeV protons up to integrated fluences between 2.1× 10(13) and 1.3× 10(14) cm(−)(2).

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. [...]

Electroweak Measurements in Electron-Positron Collisions at W-Boson-Pair Energies at LEP / ALEPH Collaboration
Electroweak measurements performed with data taken at the electron-positron collider LEP at CERN from 1995 to 2000 are reported. The combined data set considered in this report corresponds to a total luminosity of about 3~fb$^{-1}$ collected by the four LEP experiments ALEPH, DELPHI, L3 and OPAL, at centre-of-mass energies ranging from $130~GeV$ to $209~GeV$ [...]

Search for Charged Higgs bosons: Combined Results Using LEP data / ALEPH, DELPHI, L3 and OPAL Collaborations
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for pair-produced charged Higgs bosons in the framework of Two Higgs Doublet Models (2HDMs). The data of the four experiments are statistically combined. [...]

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 $b\bar{b}$. [...]

Generalized event shape and energy flow studies in $e^+ e^-$ annihilation at $\sqrt{s}$ = 91.2-208.0 GeV / L3 Collaboration
We present results from a study of hadronic event structure in high energy e(+)e(-') interactions using the L3 detector at LEP. A new class of event shape distributions are measured at and above the Z boson pole for light quark (u, d, s, c) flavours. [...]

Test of the $\tau$-Model of Bose-Einstein Correlations and Reconstruction of the Source Function in Hadronic Z-boson Decay at LEP / L3 Collaboration
Bose-Einstein correlations of pairs of identical charged pions produced in ha- dronic Z decays are analyzed in terms of various parametrizations. A good descrip- tion is achieved using a L ́evy stable distribution in conjunction with a model where a particle’s momentum is correlated with its space-time point of production, the tau-model. [...]

Observation of a VHE Cosmic-Ray Flare-Signal with the L3+C Muon Spectrometer / L3+C Collaboration
The data collected by the L3+C muon spectrometer at the CERN Large Electron-Positron collider, LEP, have been used to search for short duration signals emitted by cosmic point sources. A sky survey performed from July to November 1999 and from April to November 2000 has revealed one single flux enhancement (chance probability = 2.6X10^{-3}) between the 17th and 20th of August 2000 from a direction with a galactic longitude of (265.02+-0.42)^° and latitude of (55.58+-0.24)^°.

Radiation hardness qualification of PbWO4 scintillation crystals for the CMS Electromagnetic Calorimeter / Adzic, P. (Belgrade U.) ; Almeida, N. (LIP, Lisbon) ; Andelin, D. (Virginia U.) ; Anicin, I. (Belgrade U.) ; Antunovic, Z. (Split U.) ; Arcidiacono, R. (Turin U. ; INFN, Turin) ; Arenton, M.W. (Virginia U.) ; Auffray, E. (CERN) ; Argiro, S. (Turin U. ; INFN, Turin) ; Askew, A. (Florida State U.) et al. /CMS Electromagnetic Calorimeter Group
Ensuring the radiation hardness of PbWO4 crystals was one of the main priorities during the construction of the electromagnetic calorimeter of the CMS experiment at CERN. The production on an industrial scale of radiation hard crystals and their certification over a period of several years represented a difficult challenge both for CMS and for the crystal suppliers.

Commissioning and performance of the CMS pixel tracker with cosmic ray muons / CMS Collaboration
