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: Atmospheric neutrinos in the Soudan-2 and MACRO experiments
abstract: The results of Soudan-2 and MACRO experiments are summarized. Both experiments observe atmospheric neutrino anomalies in agreement with νμ → ντ oscillations with maximum mixing. The νμ → νs oscillations are disfavoured by the MACRO experiment at 98% C.L.

title: Search for narrow resonances in e+e− annihilation into hadrons at adone
abstract: A search for narrow resonances in the reaction e + e − → hadrons in the mass regions 1915–2345 MeV and 2970–3090 MeV has been perforned at ADONE, the Frascati storage ring. With 90% confidence level our data exclude the production of narrow resonances with integrated cross section larger than 20% of the integrated cross section for production of the J/Ψ (3100 MeV).

title: SEARCH FOR CORRELATION OF GAMMA RAY BURSTS WITH GRAVITATIONAL WAVE DATA
abstract: The first extensive search for time correlation between gamma ray bursts (GRB) and the data recorded withresonant gravitationalwave (GW)antennas is presented and discussed. The “average” algorithm is applied to the GW data obtained in correspondence of a time window of minutes centered at the GRB trigger time. No significant effect is found at a level of GW bursts with amplitude

title: Status report of the macro experiment at gran sasso
abstract: The half of the MACRO detector, a large area Monopole, Astrophysics, Cosmic Ray Observatory is nearly completed in Hall B of the Gran Sasso Laboratory. One supermodule is already taken data and the remainder will be activated in few months. A general overview of the MACRO detector, together with its physics capabilities as far as the search for point sources of high energy neutrino is concerned, will be presented.
