Milla Baldo Ceolin

from Wikipedia, the free encyclopedia

Massimilla "Milla" Baldo Ceolin , also Baldo-Ceolin, (born August 12, 1924 in Legnago , † November 25, 2011 in Padua ) was an Italian experimental particle physicist . She had been a professor at the University of Padua since 1964 and thus its first professor.

Baldo Ceolin received her Laureate Degree in Physics from the University of Padua in 1952. She began with balloon experiments on cosmic rays and then worked at Bevatron in Berkeley, where she and DJ Prowse discovered the anti- lambda particle in 1958 , the first anti-particle hyperon to be found. She also examined the kaon- anticaon system. At that time she was still working with nuclear emulsions as detectors. In 1958 she completed her habilitation in Rome (Libera Docenza) and became an assistant professor in Padua. In the 1960s she investigated the kaon system and its symmetries with bubble chambers at Argonne National Laboratory , CERN and amITEP in Moscow .

In the 1970s she turned to neutrino physics . In the NUE experiment at CERN, together with Helmut Faissner's group (Aachen) and using spark chambers as detectors , she investigated the elastic scattering of neutrinos and antineutrinos from electrons and determined a value for the Weinberg angle . She was also part of an Italian-French-Dutch-Norwegian collaboration at CERN's Super Proton Synchrotron (SPS), which examined neutral and charged weak currents of free protons and neutrons. In 1976 she proposed an experiment to observe electron-muon- neutrino oscillations , which was implemented a few years later, but could not detect any oscillations, but gave upper bounds for them. She continued the search as head of the Italian group of the NOMAD Collaboration in the 1990s at CERN. At the Laue-Langevin Institute she was looking for neutron-antineutron oscillations. She supported the development of the ICARUS experiment and its installation in the Gran Sasso laboratory.

In Padua she was head of the section of the Istituto Nazionale di Fisica Nucleare (INFN) from 1965 to 1968 and head of the physics faculty from 1973 to 1978. In 1988 she initiated the series of international workshops on neutrino telescopes at the Istituto Veneto di Scienze, Lettere ed Arti. In 1998 she retired from Padua (Professor Emeritus).

In 2007 she received the Premio Enrico Fermi , and in 1976 the Feltrinelli Prize . In 1995 she received the Benemeriti della Scienza e della Cultura gold medal and in 1978 the Benemeriti della Scuola, della Cultura e dell'Arte gold medal .

She was a member of the Accademia dei Lincei (1987), the Accademia Galileiana di Scienze, Lettere ed Arti (1966), and the Istituto Veneto (1977).

She was the coordinator of the European research network Neutrino Oscillations .
