  1. Muon catalysed fusion.
    • Study of the techniques of production of low energy muons for the muon catalysed fusion.
  2. Experiments with anti-nucleons.
    • Participation to the OBELIX experiment at CERN (Geneva);
    • Study of the annihilation of the antiproton-proton, antineutron-proton and antiproton-deuton states;
    • Meson spectroscopy, research of resonant states, paying particular attention to the exotic states foreseen by QCD;
    • Study of antiproton stopping power at low energies.
  3.   B meson physics and physics of CP symmetry violation:
    • Participation to the HERA-B experiment at DESY (Hamburg);
    • Participation to the LHCb experiment at CERN (Geneva);
    • In the LHCb experiment, with the Bologna group, has the responsibility of the analysis of the charm-less decays of the B mesons in two hadrons, which allow the determination of the γ angle of the CKM unitarity triangle;
    • Evaluation of the possible implication of the experimental measurements on the description of the quark flavor mixing  (CKM matrix and unitarity triangle).
  4. Experimental techniques:
    • Set-up of the sampling electromagnetic calorimeter HARGD of the OBELIX experiment at the LEAR of the CERN (Geneva);
    • Set-up of a new neutron spectrometer to study low neutron emissions in presence of high gamma background;
    • Design and setup of the readout and pretrigger electronics of the ECAL electromagnetic calorimeter of the HERA-B experiment at DESY (Hamburg);
    • Design and set-up of a part of the level zero trigger electronics for the  LHCb experiment at CERN (Geneva).
  5. Scientific computing techniques:
    • Design and setup of the Bologna off-line computing system for the OBELIX and HERA-B experiments for the production of Monte Carlo events and the data analysis.
    • Design and prototype test for the Tier-1 Italian regional centre for the LHCb experiment.
    • Collaboration to European projects DATAGRID and EGEE and to the Italian project INFN-Grid, to build a computational grid for the distributed computing of the LHC experiments;
    • Study and testing of High scale (tens of PiB) storage solutions with high I/O performance, focusing interest to the parallel file systems;
    • Testing, in collaboration with the CNAF of INFN, of the STORM software, which interfaces the Computational grid with the parallel file systems.
  6. Experimental data acquisition techniques:
    • Study and measurement of the data throughput and location of the bottlenecks (both in the network devices and in the software components of the operating system) in a switched Gigabit Ethernet network with high data throughput (50 GiB/s), oriented to the building of the  on-line farm for the data acquisition and the software trigger  of the LHCb experiment (the first software trigger designed for an event input rate of 1 MHz).
    • Design and set-up of the software package for the farm monitoring and control system (FMC) for the on-line farm of the LHCb experiment (scale of 2000 PC).
    • Study of 10 Gb/s technologies (focusing, in particular, to 10 Gigabit Ethernet e Infiniband) to build data acquisition and software trigger systems for the experiments of the next generation.
    • Study of the readout network for the upgrade of the LHCb experiment: analysis of solution based on Ethernet and InfiniBand.
