LHCb is one of the four main experiments taking data at the large proton-proton collider LHC at the CERN laboratory in Geneva. It is mainly devoted to the physics of beauty and charm hadrons. The Standard Model (SM) has proven to be able to describe experimental results with outstanding success. However it leaves several open questions, like the origin of the matter-antimatter asymmetry in the universe, the reason for the three replica of lepton and quarks families, the large differences existing among their masses and coupling constants etc.. The main aim of LHCb is the search for possible evidences of physics beyond the SM from the comparison of its predictions to very precise measurements. LHCb studies CP violating processes in the beauty and charm sectors and searches for evidence of rare events. LHCb has demonstrated to be well suited for extensive studies of the production and decay of all kinds of beauty and charm hadrons, it has provided a large amount of results which increase the knowledge in hadronic physics. The Milano group is part of the LHCb Collaboration which consists of physicists coming from 63 laboratories distributed in 17 different countries. Bachelor Thesis and altre and Master Thesis offered to students.

The Alpha Magnetic Spectrometer (AMS-02) is a state-of-the-art particle physics detector designed to operate as an external module on the International Space Station. It will use the unique environment of space to study the universe and its origin by searching for antimatter, dark matter while performing precision measurements of cosmic rays composition and flux. AMS-02 is built, tested and operated by an international Collaboration of 56 institutions from 16 countries.

Experimental Cosmology at microwaves - Cosmic Microwave Background

M. Gervasi, M. Zannoni, A. Baù, A. Passerini, R. Mainini

B-modes of CMB polarization are signals probing the gravitational waves background released during the inflationary epoch of the primordial universe. QUBIC is a bolometric interferometer operating from Antarctica and LSPE is a stratospheric balloon borne experiment searching for these signals. Besides, the interaction of CMB photons with the intra-cluster medium of galaxy clusters is studied to get information on the physics of the clusters and on the cosmological evolution of stuctures. Spectroscopic obeservations are carried on with OLIMPO program on stratospheric balloon and with Millimetron space program.
