Defining Absence: The Origin of "Neutrinoless" and How it Obscures the Physics of Matter Creation
Francesco Vissani
The term 'neutrinoless' is a cornerstone of modern particle physics, yet it defines a fundamental process by what is missing rather than what is created. We trace the origins of th…
From Hole Theory to Quantum Field Theory: Relativistic Fermions and the Role of Ettore Majorana (1933-1937)
Francesco Vissani
Between 1933 and 1937, the treatment of relativistic spin-1/2 particles, initially rooted in Hole theory, evolved into the modern framework of quantum field theory. This paper reco…
Insights from the History for Teaching Antimatter
Francesco Vissani
The concept of antimatter is extremely important, but not always discussed as it deserves, balancing ideas and formalism. In this note, we gather some insights to present it effect…
Neutrinos: Opening new doors
Francesco Vissani
In this contribution, which introduces the "Crossing the Portal" session of the NOW 2024 meeting, I discuss the value of the concepts of interdisciplinarity and innovation for neut…
