Detailed description of the scientific activity:

The scientific activity of Stefano Zucchelli has been and is still dedicated to experimental researches in high energy physics. As from 1979 Stefano Zucchelli continued the research, subject of his graduation thesis, of new long-lived charged particles, using a secondary beam separated by separating superconductor cavities. The experiment measured the production cross sections of light anti-nuclei up to the anti-He3 and set down higher limits to the production cross section of anti-He4 and of new stable charged particles. The experiment was a very valuable experience also because the small number of researches from Bologna and Saclay forced all the participants to a global commitment on every aspect of the activity, including the technical as well as the organizing ones.

As a Research Associate of the Northwestern University, Stefano Zucchelli took part during the 1980-1984 period in an experiment of elastic collision of proton-proton and proton-antiproton of the ISR rings of the Cern of Geneva. The experiment collected data at energy between 30.6 e 62.3 GeV in the center of mass and observed experimentally for the first time the growth of the total cross section of  proton-antiproton up to energy of 52.8 GeV in the center of mass center. The experiment also performed precise measurements of the total cross section, and of the slope and of the ratio of the real to the imaginary part of the forward proton-antiproton elastic scattering amplitude.  A close comparison of the total cross sections as function of the center of mass energy was made possible.  Stefano Zucchelli was responsible for the physics simulations and for the data analysis, in particular in relation to the cross section measurement.  He also contributed to the construction of the apparatus for the measurements at large scattering angles.

He then continued the study of the hadronic elastic interactions at higher energy, using the  “Tevatron Collider “  at the Fermilab in Chicago, The Tevatron Collider was the first particles accelerator running with superconductive magnets. It started working in 1987 and was able to produce collisions between protons and anti-protons at energies between 300 and 1800 GeV in the center of mass. The experiment precisely measured  the slope of the elastic peak, the total proton-antiproton cross section, the elastic and single diffractive cross section and the ratio between the real and the imaginary part of the forward proton-antiproton elastic scattering amplitude up to 1800 GeV in the center of mass.   Quite important is the experimental observation that the differential elastic cross section does not show any structure in the measured t range  ( 0.03 < t < 0.6 )  indication perhaps of an asymptotic behavior  already at the Tevatron energies. Stefano Zucchelli's contribution to this experiment was fundamental. Besides participating to all the research phases, from the experiment planning to the analysis of the collected data, he also collaborated to the construction planning and installation of the part of the apparatus crucial for the measurement of the smaller angles, the so-called “Roman Pots”. 

In 1990 Stefano Zucchelli joined the CDF collaboration, an experiment at the Fermilab Tevatron Collider. CDF is an international collaboration of many institutions, among which the University of Bologna and the INFN section of Bologna.   Of great importance was the discovery made by the experiment in 1994 of the existence of the “top” quark and the precise measurement of its mass and production cross section. The CDF detector was an all-purpose apparatus allowing one to move in all the fields of study of the hadronic interactions.  The Bologna group gave its contribution in analyzing the large amount of data collected  at low four momentum transfer (low Pt), the so called  Minimum Bias  and Zero Bias triggers, undertaking starting on  2006  the full  reponsability of the  low Pt data reduction into standard n-tuples.  The analysis of the Minimum Bias trigger  gave an essential contribution, in terms of calibration and control of the several detectors of the CDF experimental apparatus.  The specific studies carried out  by the Bologna group on Minimum Bias data have led to important observations of invariance behavior of the low Pt component  ( soft interactions)  of the  hadronic multibodies production,  as function of center of mass energy.   

These results have been already published for the great part, but some analysis is still under way, with a view of a next publication.  Stefano Zucchelli actively participated to the Bologna group data analyses, in particular the one centered on the systematic study of the low Pt interactions. In addition the Bologna group, directly coordinated by the undersigned, collaborated to the construction of an electromagnetic and hadronic calorimeter of new design.  The instrument, that innovatively matched the use of wave length shifter fibres with scintillator tiles, was part of the CDF upgrade (Plug and End Cap calorimeters). Finally the Bologna group contributed to the planning and realization of the ISL (Intermediate Silicon Layer), the detector's mechanic support, modernization of the VTX of  CDF II. As a whole the detectors upgrade have led to the renovation and substitution of about two thirds of the CDF apparatus and have given birth to a second phase of data collection, called run II, that finally ended in 2011.

In the years 2000-2004 Stefano Zucchelli was Coordinator for the Bologna section of the Italian National Institute for Nuclear Research (INFN) of the INFN physics activity “Group I” which is in charge of the researches carried out with particle accelerators.  The office is elective and has a three year mandate. It involves the coordination of the several experimental groups of the Section and the representation of Bologna in the National Scientific Commission I which examines and coordinates all the INFN scientific activities relevant to the physics research of the elemental particles and basic interactions conducted at the particle accelerators  and the assignment of the financial resources of the sector. 

Since 2008 he is also member of the Cuore experiment. This experiment, which will take place at the INFN Underground Gran Sasso Laboratory, has the aim to measure or set limits on the neutrino mass and to determine the nature, either  Majorana or Dirac, of the neutrino, by studying  the neutrinoless double beta decay. The detector will be a cryogenic detector, a bolometer, made of tellurium oxide crystals. The Bologna group, coordinated by the undersigned, has up to now actively contributed to the construction of the detector. In particular the group took care of the preparation at the Gran Sasso laboratories of a storage room free of radon for the storage of more than a thousand tellurium oxide crystals and to realize the database for the management of the same crystals. For what concerns the commissioning activities, the group is responsible for the delicate movement of the cryogenic vessels of the Cuore cryostat. It also contributes to the set up of the experiment's Slow Control software.

Since the beginning of 2012 Stefano Zucchelli is the P.I. in charge of the CDF and CUORE experiments of the INFN section of Bologna.  

Since 2014 he is a member of the LHC-b experiment at Cern in Geneva, Switzerland.
