title: PAT: The CMS Physics Analysis Toolkit
abstract: The CMS Physics Analysis Toolkit (PAT) is presented. The PAT is a high-level analysis layer enabling the development of common analysis efforts across and within Physics Analysis Groups. It aims at fulfilling the needs of most CMS analyses, providing both ease-of-use for the beginner and flexibility for the advanced user. The main PAT concepts are described in detail and some examples from physics analyses are given.

title: Performance Study of the CMS Barrel Resistive Plate Chambers with Cosmic Rays
abstract: In October and November 2008, the CMS collaboration conducted a programme of cosmic ray data taking, which has recorded about 270 million events. The Resistive Plate Chamber system, which is part of the CMS muon detection system, was successfully operated in the full barrel. More than 98% of the channels were operational during the exercise with typical detection efficiency of 90%. In this paper, the performance of the detector during these dedicated runs is reported.

title: Search for supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV
abstract: Results are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using a sample of proton-proton collision data collected at sqrt(s)=7 TeV with the CMS detector at the LHC in 2011, with the missing transverse energy distribution as the principal search variable. The integrated luminosity of the sample is 4.98 inverse femtobarns. The observed number of events is found to be consistent with the standard model expectation, which is evaluated using control samples in the data. The results are used to constrain cross sections for the production of supersymmetric particles decaying to b-quark-enriched final states in the context of simplified model spectra.

title: Performance and operation of the CMS electromagnetic calorimeter
abstract: The operation and general performance of the CMS electromagnetic calorimeter using cosmic-ray muons are described. These muons were recorded after the closure of the CMS detector in late 2008. The calorimeter is made of lead tungstate crystals and the overall status of the 75 848 channels corresponding to the barrel and endcap detectors is reported. The stability of crucial operational parameters, such as high voltage, temperature and electronic noise, is summarised and the performance of the light monitoring system is presented.

title: EVIDENCE FOR THE EXISTENCE OF A NEW VECTOR MESON OF MASS 1.82 GeV OBSERVED IN e+e- ANNIHILATIONS AT ADONE
abstract: Evidence is presented for the occurrence in e+e− annihilation of a new vector meson of mass 1821 ± 16 MeV and Γ = 31 ± 15 MeV.

title: Long baseline neutrino oscillations at Gran Sasso
abstract: A short summary of the present long base line neutrino experiments in the Gran Sasso Laboratory using the CERN to Gran Sasso neutrino beam is given. This beam has been designed to provide unambiguous evidence for ν μ → ν τ oscillations.

title: Atmospheric Neutrinos
abstract: The results of experiments on atmospheric neutrinos are summarized, with the important exception of Su-perkamiokande. The main emphasis is given to the Soudan-2 and MACRO experiments. Both experiments observe atmospheric neutrino anomalies in agreement with νµ → ντ oscillations with maximum mixing. The νµ → νs oscillation is disfavored by the MACRO experiment.

title: Matter effects in upward-going muons and sterile neutrino oscillations
abstract: The angular distribution of upward-going muons produced by atmospheric neutrinos in the rock below the MACRO detector shows anomalies in good agreement with two flavor ν μ → ν τ oscillations with maximum mixing and Δm 2 around 0.0024 eV 2 . Exploiting the dependence of magnitude of the matter effect on oscillation channel, and using a set of 809 upward-going muons observed in MACRO, we show that the two flavor ν μ → ν s oscillation is disfavored with 99% C.L. with respect to ν μ → ν τ .
