Reconstruction of CNGS neutrino events in the emulsions of the OPERA experiment
The OPERA experiment aims at the direct observation of ν_mu -> ν_tau oscillations in the CNGS (CERN Neutrinos to Gran Sasso) neutrino beam produced at CERN; since the ν_e contamination in the CNGS beam is low, OPERA will also be able to study the sub-dominant oscillation channel ν_mu -> ν_e. OPERA …

Drift Tubes Trigger System of the CMS Experiment at LHC : Commissioning and Performances
In this thesis the performances of the CMS Drift Tubes Local Trigger System of the CMS detector are studied. CMS is one of the general purpose experiments that will operate at the Large Hadron Collider at CERN. Results from data collected during the Cosmic Run At Four Tesla (CRAFT) commissioning …

Hardware and software development of a multichannel readout board named CARLOSrx for the ALICE experiment
ALICE, that is an experiment held at CERN using the LHC, is specialized in analyzing lead-ion collisions. ALICE will study the properties of quarkgluon plasma, a state of matter where quarks and gluons, under conditions of very high temperatures and densities, are no longer confined inside hadrons. …

Applications of High Speed Configurable Logic Devices in Modern Particle Physics Experiments
Several activities were conducted during my PhD activity. For the NEMO experiment a collaboration between the INFN/University groups of Catania and Bologna led to the development and production of a mixed signal acquisition board for the Nemo Km3 telescope. The research concerned the feasibility …

Sensitivity of the Top quark mass measurement with the CMS experiment at LHC using t-tbar multijet simulated events
This thesis comes after a strong contribution on the realization of the CMS computing system, which can be seen as a relevant part of the experiment itself. A physics analysis completes the road from Monte Carlo production and analysis tools realization to the final physics study which is the …

Evaluation of a multi variated analysis for the selection of t-tbar multijet events in the current CMS implemented environment at LHC
In the present study we are using multi variate analysis techniques to discriminate signal from background in the fully hadronic decay channel of ttbar events. We give a brief introduction to the role of the Top quark in the standard model and a general description of the CMS Experiment at LHC. We …

Experimental characterization and computational modeling of N-doped Carbon Dots for future optoelectronic applications
The rising demand for more environmental-friendly and cost-effective fluorophores in optoelectronics and photonics pushed the research on alternatives free of semiconductor elements or rare-earth-based materials. A promising green and low-cost alternative is currently represented by carbon-based …

Measurement of inclusive muon elliptic flow in pp collision at √s=13 TeV with the ALICE Experiment
Heavy-flavour hadrons are produced in hard-scattering processes in hadron collisions before the Quark–Gluon Plasma (QGP) formation. They successively interact with the QGP via inelastic and elastic processes. The elliptic flow v2 is one of the signatures of QGP formation. The ALICE experiment has …

Studies of Ξ+c production in pPb collisions
… respectively, collected by the LHCb detector in 2016. The Ξc+ events are reconstructed in the detector through the decay of the Ξc+ baryon in a proton, a kaon and a pion. The analysis is performed over the transverse momentum range 2.0 < pT < 12.0 GeV/c in the regions of rapidity from 1.5 to 4.0 …
