Maria Fidecaro (1930-2023[1]), née Cervasi,[2] was an Italian experimental physicist with a focus on particle physics.

[7] The majority of her research relates directly to the experiments, including interpreting the measurements and results in the search for new particles.

In Maria's early works in the 1960s, she studied the nucleon-nucleon charge exchange scattering,[8] recorded data on high-energy electrodynamic processes.

[10] In the 1990s, she investigated the design and test of a prototype gas-sampling electromagnetic calorimeter of high granularity[11] and collaborated on the construction of a position-sensitive photon detector for the CPLEAR experiment.

[12] CPLEAR experiment aims to carry out precision measurements of CP, T and CPT violation of the neutral kaon systems.

The newly achieved level of precision of the experiments called into question the validity of some of the often tacitly assumed hypotheses in particle physics.
