ALICE (A Large Ion Collider Experiment) is the heavy-ion detector designed to study the physics of strongly interacting matter and the quark-gluon plasma at the CERN Large Hadron Collider (LHC). Following a successful Run 1 which ended in February 2013, the ALICE data acquisition (DAQ) entered a consolidation phase to prepare for Run 2 which will start in the beginning of 2015. [...]

The data acquisition system (DAQ) of the CMS experiment at the CERN Large Hadron Collider assembles events at a rate of 100 kHz, transporting event data at an aggregate throughput of 100 GB/s to the high level trigger (HLT) farm. The HLT farm selects interesting events for storage and offline analysis at a rate of around 1 kHz. [...]

The AEgIS Experiment / Knecht, A (CERN) ; Aghion, S (Milan Polytechnic) ; Ahlen, O (CERN) ; Amsler, C (Bern U., LHEP) ; Ariga, A (Bern U., LHEP) ; Ariga, T (Bern U., LHEP) ; Belov, A S (Moscow, INR) ; Bonomi, G (INFM, Brescia ; INFN, Pavia) ; Bräunig, P (Kirchhoff Inst. Phys.) ; Bremer, J (CERN) et al.
The AEgIS experiment aims at performing the first test of the Weak Equivalence Principle of General Relativity in the antimatter sector by measuring the gravitational acceleration acting on a beam of cold antihydrogen to a precision of 1%. The installation of the apparatus is making good progress and large parts were taken into operation. [...]

Measuring the gravitational free-fall of antihydrogen / Storey, J (Bern U., LHEP) ; Aghion, S (Milan Polytechnic ; INFN, Milan) ; Ahlen, O (CERN) ; Amsler, C (Bern U., LHEP) ; Ariga, A (Bern U., LHEP) ; Ariga, T (Bern U., LHEP) ; Belov, A S (Moscow, INR) ; Bonomi, G (INFM, Brescia ; INFN, Pavia) ; Bräunig, P (Kirchhoff Inst. Phys.) ; Bremer, J (CERN) et al.
Antihydrogen holds the promise to test, for the first time, the universality of free-fall with a system composed entirely of antiparticles. The AEgIS experiment at CERN’s antiproton decelerator aims to measure the gravitational interaction between matter and antimatter by measuring the deflection of a beam of antihydrogen in the Earths gravitational field ( $\overline {\textrm {g}}$ ).

Status of the Level 0 Trigger Processor of the NA62 Liquid Krypton Electromagnetic Calorimeter / Bonaiuto, V (Rome U., Tor Vergata) ; De Simone, N (Rome U., Tor Vergata) ; Federici, L (Rome U., Tor Vergata) ; Sargeni, F (Rome U., Tor Vergata) ; Badoni, D (INFN, Rome2) ; Fucci, A (INFN, Rome2) ; Paoluzzi, G (INFN, Rome2) ; Salamon, A (INFN, Rome2) ; Salina, G (INFN, Rome2) ; Santovetti, E (INFN, Rome2) et al.
The NA62 experiment at the CERN SPS aims to measure the Branching Ratio of the ultra-rare decay , collecting about 100 events in two years of data taking with a signal to background ratio of 10:1. A hermetic photon veto system has been designed to efficiently reject the π0 background, one of the main background sources, and the 20-ton liquid krypton calorimeter is a fundamental component of such system in the angular acceptance region 1-10 mrad.

Our codes to evaluate the solar modulation of Galactic Cosmic Rays (HelMod) and to trace the the charged particles inside the Earth magnetosphere (GeoMag) have been implemented as webmodels in the two websites, helmod.org and geomagsphere.org. HelMod model uses a 2D Monte Carlo approach to solves the Parker transport equation, obtaining a modulated flux of Cosmic Rays for a period starting from 1990. [...]
