Strangeness physics: the first measurement of the kaonic deuterium exotic atoms transitions at the DAFNE Collider (SIDDHARTA-2) Instrumental/Data analysis

C. Curceanu

The PhD student will participate to the preparation and installation of the SIDDHARTA-2 experimental apparatus on the Frascati electron-positron collider DAFNE. SIDDHARTA-2 will measure, for the first time, kaonic-deuterium transitions with novel solid state detectors (Silicon Drift Detector). The results of SIDDHARTA-2 will have implications in the particle and nuclear physics fields and in astrophysics (is there strangeness in the neutron stars?), including the interpretation of the gravitational waves pattern emitted by neutron star binary systems. The PhD student will have an active role in data taking, data analysis and results publication. He will work within an international collaboration of 10 institutions from 7 countries from all over the world, and this will open unique opportunities for a carrier in the research field at the international level.
Study of hadron multiplicities in the light flavour sector in ultra relativistic heavy ion collisions with the ALICE detector at CERN Data analysis

V. Muccifora

By studying ultra-relativistic heavy-ion collisions at the LHC, the ALICE experiment aims at understanding the strong interaction aspects that are still not completely clear, in particular the origin of the phenomenon of quark confinement and the mechanism of particle mass generation. Important information to reach this goal, can be obtained by studying the evolution of the multiplicity of the hadrons produced in the interactions, since it allows to learn on the dynamics of the strong force. The thesis work is centered on the analysis and on the discussion of the data collected by ALICE in pp, pA and AA interactions, and foresees to spent time at CERN to take part of the work of the analysis groups.
Study of strangeness production in ultrarelativistic heavy ion collisions with the ALICE detector at CERN Data analysis

A. Fantoni

By studying ultra-relativistic heavy-ion collisions at the LHC, the ALICE experiment aims at understanding the strong interaction aspects that are still not completely clear, in particular the origin of the phenomenon of quark confinement and the mechanism of particle mass generation. The study of “strangeness” production allows to understand the mechanism of mass generation and the dynamics of the Quark Gluon Plasma. The thesis work is centered on the analysis and on the discussion of the data collected by ALICE in pp, pA and AA interactions, and foresees to spent time at CERN to take part of the work of the analysis groups.
Development of a high-resolution, multi-layered, low-material Monolithic Active Pixel Sensors (MAPS) tracking system for the ALICE detector at CERN Instrumental

F. Ronchetti

The ALICE apparatus is a system of detectors for the study of ultra-relativistic heavy-ion collisions at LHC. The accelerator will undergo a major upgrade to increase the luminosity, and this will imply interaction frequencies for Pb ions of 50kHz. Therefore, also the apparatus should be upgraded to improve its capabilities. For this purpose, it will be built a new vertex detector made of silicon pixel (ITS) with high resolution and reduced thickness. The thesis work offers the opportunity to participate to the construction, characterization and installation at CERN of the new ITS detector.
Measurement of the beam asymmetry in eta’ photo-production off the proton at BGO-OD Instrumental/Data analysis

P. Levi Sandri

The beam asymmetry it’s a variable extremely sensitive to the details of the photon-nucleon interaction and it allows to discriminate among different theoretical models. The thesis work regards the measurement of the asymmetry in meson eta’ photo-production between the threshold and 1.8 GeV of incident photon energy, by using the Bremsstrahlung coherent beam of ELSA (University of Bonn) and the detector BGO-OD. It is foreseen hardware work (tuning and characterization of MRPC chambers, monitor and calibration of the BGO calorimeter) together with data analysis. The MRPC chambers of BGO-OD apparatus cover essential angles for the measurement feasibility and will be devoted to the detection of the recoil proton, while the calorimeter will detect the eta’ decay products. BGO-OD is an international collaboration that includes INFN, German Institutions (Bonn PI, Bonn HISKP, Gießen), Russian ones (INR Moscow e PNPI Gatchina) and the Universities of Edinburgh and Basilea.
Experimental studies of quantum mechanics (Pauli Exclusion principle and collapse models) and implications for the (new) quantum technologies. Data analysis

C. Curceanu

Quantum mechanics is a pillar of modern physics, but still triggers many debates and detailed studies to improve our understanding and to develop new quantum technologies. The PhD student will participate to the realization of new quantum mechanics experiments: VIP2 (test of the Pauli principle violation), test of collapse models. The experimental detectors will be realized at the Frascati laboratories (LNF), and the experiments will be carried out at the underground laboratories of Gran Sasso (LNGS). The PhD student will participate to the data analysis and interpretation within an international collaboration (VIP2), and to the study of the implications for future quantum technologies, within the European project COST Action CA15220 – Quantum Technologies in Space.
