Elementary Particle Research group

Gruppo di ricerca in Fisica Sperimentale delle Particelle

The group takes part to experiments with accellerators involving extremely wide and international research teams. The center of activity is the CERN in Geneva, where the Large Hadron Collider is now operative.

The Elementary Particle Research Group, composed of faculty, researchers, post-docs and graduate students,  works in close connection with the Department of Physics of the University of Pisa with the Istituto Nazionale di Fisica Nucleare (INFN, Sezione di Pisa), which provides  the financial support to the groups in which the SNS personnel is involved.  
The members of the group are involved in the following experiments:

BABAR
, located at the PEP-II storage ring (Stanford, USA), studies the differences between matter and anti-matter in coherent B-meson pairs, performing precision measurements and searches for light New Physics with events from e+e- collisions around 10.58 GeV. The experiment collected data between 1999 and 2008, and continues to be very active in the analysis and publication of papers.

CMS
, installed at the LHC accelerator at CERN (Ginevra, CH), studies the proton-proton collisions at 13 TeV, aiming at measuring the Higgs Boson properties, and searching for super-symmetric particles and new particles with mass up to few TeV. CMS is currently operating  and taking data.

LHCb
, installed at the LHC accelerator at CERN (Ginevra, CH), studies the proton-proton collisions at 13 TeV. LHCb is a specialized b-physics experiment, that  is measuring the parameters of the quark-mixing matrix (CKM matrix) and the CP violation in the  decays of b- and c-hadrons. LHCb is currently operating and taking data. 

RETINA, a R&D project aiming at demonstrating the feasibility of a real-time tracking device based on the so-called "Artificial Retina Algorithm", able to fulfill the needs of Level-0 trigger of LHC experiments (bunch crossing frequency of 40MHz), through the designing and realization of hardware prototypes implemented on commercial field-programmable gate array (FPGA).

BABAR, CMS e LHCb are financially supported by the CSN1 (Particle Physics with Accelerators), while the RETINA project by the CSN5 (Technological and Applied Research in Physics).
